  • Aluminum conductor PVC insulated power cable marked with 1.1KV grade should be applied to several applications in control room
  • For all protection/control/instrumentation purposes, PVC insulated control cables should be used. These cables should be of minimum 2.5 sq.mm in size
  • AC input cable should be of PVC insulated, armoured, stranded copper cable. DC output cables from the battery and charger should be of PVC insulated, stranded copper cable.
  • Separate cable should be applied for AC and DC
  • Sizing of power cables should be done while considering continuous current, voltage drop, and short circuit current. Size of the cable should be correct so that voltage supply can be hurdle free.

Cable insulation considerations

The sheath insulation should have a compound based on one of the following-

  • PVC
  • Ideal co-polymers with major constituent vinyl chloride
  • PVC insulated 1100V grade power

Outer sheath considerations –

Outer sheath should be intended with over armouring. Manufacturers need to apply outer sheath by extrusion, so that it fits closely over armouring.

Outer sheath should have features like fire resistance, high tolerance, water proof, heat resistance, weather resistance, etc.

Inner sheath considerations –

For multicore power cables, manufacturers should use inner sheath made of extruded PVC.

Armouring considerations –

Armouring should be applied over the inner sheath used for multicore power cable. It should be done with galvanized round steel wires.

Guarantee/ warranty considerations –

It is the bidder who ensures electrical characteristics. If materials used for constructing power cables failed to meet guarantee, it will be rejected rightfully. It is the responsibility of the bidder to submit guaranteed technical particulars during detailed engineering along with other documents or drawings.

Submersible Flat Cable India: Properties and Selection

Submersible-Flat-Cables

Today electrical instruments are found in all kinds of terrains — from deep underwater to far in the space. This also means that we need cables that can connect to such instruments. These are cables that can withstand adverse and corrosive environments. One such example is the submersible flat cable that are used in submerged conditions.

Submersible flat cables in India are typically used for submersible pumps in deep wells. They are also used in all kinds of underwater projects. As the name suggests, their speciality is in withstanding the corrosion caused by water. They can be used in both fresh water and seawater. In salt water the cable must be able to survive in even more corrosive environment.

Submersible cables are also used in high moisture environments where there is a high and constant exposure to water, such as irrigation. Even if not completely submerged, the cable attaching to the pump is exposed to constant exposure to water. The cables here Some locations where submersible pumps and submersible cables are found are:

 — Boreholes

— Deep under well

— Sewage treatment plants

— Deep sea projects

— Firefighting

— Offshore drilling rigs

— Irrigation

 What makes submersible cables different?

 A submersible cable comes under a special category of cables because of the environment it is found in. This also demands certain properties in the cable. Some of these are

— Resistance to moisture: Since the cable is submerged in water, it must be able to withstand the corrosive effect of water.

— Resistant to chemicals: In some environments like sewage treatment plants, a cable is exposed to highly corrosive environments with high amount of dissolved chemicals. The cable must remain instant and withstand any corrosion.

— Resistant to abrasions: Water often has tiny abrasive particles, such as rock with ragged edges or other debris. Over time such particles can cut the cable. This can be very dangerous, since water is very conducive to electricity. Hence, submersible flat cables in India have an extremely tough and durable insulating layer and jacket.

— Resistant to grease: Submersible cables are often exposed to high levels of grease and oil since they are often attached to implements like submersible pumps. This means that they must also have resistance to oil and grease.

— Long flex life: This comes from their strong structure. But long flex life is also a necessary requirement in submersible cables. Since underwater cables usually have to maintain free movement underwater, which requires a good flex life.

All submersible cables are not the same. There are many kinds of submersible cables in India. These can be categorized as single or multiple conductor, flat or round. In flat or round, submersible flat cable India are most popular. This is because flat cables have excellent flexibility. However, the type of cable will mostly depend on the function it performs. These usually have PVC insulation and rubber coating.

Choosing the right cable:

Choosing the right cable is important because of the demanding conditions that submersible cables are usually placed in. The task becomes more difficult because of the many types of cables available in India. But a wrong choice means that you reduce the life of the cable and possibly endanger the entire project.

For instance, cables with water pumps at the depth of 500m or more have Rubbe 3 or Rubber4 core. These also have an extra insulation. These cables have high ability to withstand water fluctuations as well as oil and water corrosion. On the other hand, sewer systems typically use PVC3 – PVC4 cables. This is because the cables have a high resistance to acidic and toxic elements. These usually contain three-stranded bare copper conductors. When selecting between round and submersible flat cables in India

The other factor you must see is the certification of the cable. Check for certification such as compliance with ISO standards. Since it is impossible to check for reliability of every cable, certification is the only reliable means of judging quality. You must also select a manufacturer or supplier who can also supply related components.

Conclusion:

With rising applications of submersible cables, more and more industries and projects now use these for various projects. Fortunately, high specialization in the industry means that we have every kind of cable to select from. However, it is important to understand what we are looking for before we buy the cable.

Solar cable Manufacturers Bring Tips For Making Right Connections For Best System Performance

Solar Cables ManufacturersHow poor-quality and wrongly installed inverter cables and battery affect the solar system? Ever wonder Solar Cable Manufacturers always advice to keep the battery based system in good condition and get installation services from experts only? It is because such bad practices can cause troubles in the function and safety of any battery based system. This is why it is important to select the right cables and install them in right way.

It is a perception of the people that battery and inverter cables are costly and it is a tempting place to cut costs, but getting cheap cables can significantly affect the performance of the inverter and batter based system. It will feel like having old tires on a high performance car. In other words, you save money, but you cannot ensure great performance and safety.

You have facility to purchase preassembled cables or simply get them book at online website. The thing is that you cannot build them yourself until you know how to do it. The details are important to know-
•    Battery cables and their ring terminal connectors carry high power current.
•    Battery cables and their ring terminal connectors are used in harsh environments where they can encounter sulfuric acid, high temperatures, hydrogen gas, and different metals.

For battery and inverter system, the largest conductors in the system are used for connecting all of the batteries and then exiting the battery box in order to connect to the inverter. As manufacturers mainly intend all battery-based inverters in a way that users can operate them at 48 VDC or lower, they need large cables to handle high currents without critical losses. The sizes of these cables are influenced by the voltage of the battery.

To connect the components of solar system, you may need to use right sized wire to ensure low energy loss and to keep away possible damage from overheating and fire.
Once you connect the solar panels to the input terminals, you can use the same sized wire for connecting the charge controller output to the batteries. Such wires will be located closer to the batteries.

Some Safe Work Practice Tips Shared by Power Cable Manufacturers

power-cable

At the unit of power cable manufacturers, there are certain responsibilities shared by people to perform safe work practice with dedication. There is a manager health, safety and environment that is responsible for maintenance and ownership of this standard. Then there is Manager training that train the staff. Others are authorized persons who comply with this standard.

There are certain works that you can perform with high voltage transmission cables i.e. it will be necessary to have the HV cable isolated. The type of work includes-

  • Work on gas or oil cubicles and external pipe work if there is any risk of draining of oil from the cable. Loss of oil will affect the cable insulation integrity.
  • Connection and reading of pressure gauges along a route of cable will be needed during work in order to determine the oil leakage area. The readings are accurate when the cable is in a stable thermal condition that you can obtain with the cable off load.
  • If you are using modern cables, it is suggested that the cable be isolated even for casual movements. Take it as a suggestion only; we are not forcing you to implement it.

What are the work procedures?

Workers who are making maintenance practices for cable follow certain work procedures that are as under-

  • They make request for access with the cable isolated to access form with LV. If quick recall is needed for system reasons, some arrangements should be made to ensure workers will be available.
  • If further work is not required the LV access authority should be void and the cable must be returned to service.
  • It is the responsibility of the controller to check the further work requirements with field workers and make apt arrangements accordingly.

It is critical when developing safe working procedures to precisely make assessments regarding hazardous voltage rises at work site, and where required give a thought to these basic safe working principles-

  • While working on high voltage cable conductor, bonded earth mat working conditions should be employed by the workers. If it is not possible, they should adopt insulated working conditions.
  • One should not introduce remote earths to the local work site mat situation.
  • One should keep the conductors (being worked) as short as possible by disconnecting phase conductors and / or sectionalisation of cable sheath.
  • To maximize the shielding effect, one should maximize the number of continuous and earthed parallel conductors.

These are the considerations followed by power cable manufacturers when they deal with high voltage cables. For more details, you can anytime contact to proficient manufacturing team and ask your questions.

How do the Elevator cables perform?

Elevators make life easy for everyone. And the most popular elevators that have been helping people save time and energy for decades now are the cable-run elevators. The elector cables are to be appreciated here for doing the job right and having us all reach heights or lows in just a matter of seconds.

Cable elevators function on a basic principle where the elevator raises with a traction caused by a cable looped sheave which is in turn linked to an electric motor. As the motor starts turning one side, the elevator raises and when the motors turns the other way, the elevator is lowered. And all these are housed in one machine box that is above the elevator shaft.

Elevator cables play an important role in the functioning of the elevators which are more versatile and efficient as compared to the hydraulic ones.

Now, one thing that we should note is that the elevator cables are designed specially to withstand high amounts of mechanical stress and interestingly, they are a part of the world’s fastest and highest elevators.

Most of the elevators function through flat elevator cables which are approximately in between 80 meters to 400 meters long depending upon the height of the building or number of floor the elevator has to reach.

Elevator cable is an important connection that links the elevator and the controller; and in the traditional elevators, the power and signal data in carried through the cable that travels.

All types of lift cables are easy to install and they come with a spectrum of designs to choose and they priced differently based on the materials used.

Most buyers prefer procuring lifts that run on elevator cables for they are durable, reliable and can be manually operated easily during power cuts for people to get off it.

And when it comes to choosing the best design or type of the elevator cable, the whole decision revolves around cost-effectiveness and reliability.

Now according to the market figures, the flat type is relatively lesser than the round cables as the flat ones can form smaller loops than the round ones. And therefore, flat ones are preferred where the loop clearance has minimal space. On the other hand, when it comes to achieving the right number of conductors, flat ones are to be combined several times and the single ones can be combined just by a single round. Therefore, apart from just the cost-effectiveness, the flat cables and the round cables are to be chosen according to the elevator construction position and the space available for the cable loops.

Elevator cables manufacturers in India have grown to be experts in providing exclusive designs to the buyers and the installation has become all the more simple as compared to the earlier times.

Although the manufacturers have a lot of information to bombard the buyer with, it’s important that an elevator contractor naturally has greater knowledge of which material is to be used so as to ensure that the utility of the elevator is at its best.

 

Everything About Control Cables In India And How They Are Different From Power Cables

And the advantage of using these cables is that they are versatile at operation in various weather conditions be it dry or wet or moist environmental scenarios. These cables are comparatively easy at installation front and are definitely reasonable cost wise. Considering their versatility, they are used in air conditioners and other relative electronic appliances which require something within them to withstand any harsh environmental conditions.

Special PVC control cables are different to that of the general PVC control cables. Right from the color to their functioning they are different. Colored in black, these PVC cables are in great demand in different parts of the globe with specific reference to Eastern, South-European and Arabian nations. However, one disadvantage of these cables is that they are not compatible to underwater circumstances.

PUR Control Cables

Just like the multicore cables that are known for reliability and durability, these single core one also are highly flexible and their utility is more in drag chains. This cable has a greater demand and value in the international market as it is exceptionally preferred in the exporting industries, in the designing of robots and other machinery parts that are automated.

 

 

 

Will The Recycling of PVC Cable Waste Benefit Exporters

Recycling of PVC Cable Waste

When we use the word ‘recycling’, sudden thoughts come across – what, how, why. The term recycling is magical and delivers benefits to environment in every way. There is no particular thing for which recycling word is invented. It is meant for everything – be it your book, glasses, laptops and PCs, or wires. PVC cables exporters explain that recycling of pvc cable waste requires energy input. Yes, production of stuff do requires energy and recycling is one of such processes. Saving materials are easy to outline, but you need to work on it and prepare clear report of all the energy used and transformed in each process involved in recycling.

It is true that every step of recycling needs energy to separate or purify a material. To determine the winner in the race of ‘recycling the junk’ and ‘producing the new’, there are some great raft of things to consider.

Take an instance of cable wire. Most of the electric cable wires have a copper wire jacketed with PVC insulation. Recycling of copper definitely makes sense because it is a non-renewable metal found on earth. Mining of copper may involves tons of energy and force that will cost more. With recycling option, you can save energy, time, and money. So, recycling option is a clear winner, indeed. What about PVC? You should know that production of PVC is not done through mining. Resins from which PVC is made are extracted through processing of crude oil and chemically transformed into PVC.

Gathering old cables and forwarding them to recycling department, then washing and melting them requires time investment and loads of energy, since trucks and industrial plants and transformers usually run on fossil fuel. So, what is the best thing to do? Of course it is PVC recycling, and not PVC production process.

Though, the process of recycling seems complex, but technology has made everything so easy and convenient for people. Today, engineers have released programs that make recycling easy to perform. The software swiftly models the process and makes it reliable option for the person.

PVC cables exporters recommend recycling of pvc cable waste to save energy and time. It is the best way to conserve environment and fossil fuel. Do you agree to their perspective? Do you have your perspective to share? We won’t mind if you share it with us.
