Electric power cables are the most intrinsic ones in transmitting and distributing electric power. They make power distribution from transmission systems to the end user appliances, quite easy. A typical power cable is an enclosure of a set of electric wires in a protective sheath.
The design, construction and the material used to make a power cable depend on the environmental conditions, voltage and the power carrying capacity.
A power cable’s components include a stranded copper conductor, a semi-conductive screen layer, an insulator, a filler and tape, a copper tape screen layer, a stainless steel wire armor and a PVR inner sheath.
The advantages of a electric power cables are:
- They maximize the temperature of a conductor, thereby facilitating power transmission
- The electric power cables are resilient to harsh environmental conditions
- Due to their best resistance capacity, these cables can last long
- They need a very less land as per width for installing
- They don’t demand greater maintenance sessions or repair costs
- Most importantly, power cable lessen the transmission losses
Formed with a couple or more electrical conductors that are merged together under a cover, the power cables facilitate power transmission and they are moreover quite reliable and durable.
Power cables are available in varied sizes, different colors and a variety of materials which are specifically made to fulfill certain specific functions either in domestic systems or in commercial systems.
A power cable is a basic composition and combination of a conductor, insulation and a protective sheath.
Mostly power cables are made out of either aluminum or steel. These cables are available in a variety of types as per customer requirement. Be it fire-resistant or heat and moisture resistant, you get power cables with those specifications in the market.
