Power Cable overview & Its Types

Two or more electrical conductors held with an assembling sheath constitute a Power Cable.  The assembly is used for transmission of electrical power.  Power Cables are basically used for the transmission of electricity.  Generally,  conductors, insulation and a protective jacket are the three major components of a Power Cable.  Power Cables are either installed as permanent wiring in buildings or laid underground.  Sometimes,  Power Cables are exposed and run overhead on streets.

Types of Power Cables:

• Submarine Power Cables: The Submarine Power Cables carry current under water surface.  These cables are used under freshwater as well as salt water.  To facilitate underwater electric transmission, the Submarine Power Cables are made using polypropylene, a thermoplastic polymer. This makes the cables resistant to chemical solvents,  acids and bases present underwater.
• Nonmetallic Variant B Cables: Nonmetallic Variant B Cables are made up of flame resistant nonmetallic sheaths. These cables are resistant to damages caused due to sunlight exposure or moisture. They are laid in attics, under floor and on walls.
• Aerial Cables: Aerial Cables are widely used for telecommunication. These Cables are mostly installed in transmission towers or poles. The Aerial Cables are resistant to ultraviolet rays. Besides, these cables are completely insulated and pose no threats of electrical shocks to users.
• Steel Wired Armored Cables: Steel Wired Armored Cables are damage free and very strong. The armor of these cables is made of steel and the sheath is made of Polyvinyl Chloride. Steel Wired Armored Cables are mostly used for cable ducting and power networks.

Evidently, different types of Power Cables are available for varied power transmission applications. However, buying the requisite Power Cables from reputed Electric Cable Manufacturers is very important to ensure safe transmission of electricity. No compromise on the quality of cables can be afforded as a minor defect can cost lives. One must always be sure about the quality of Electric Cables before using them. And therefore, only the trusted Electric Cables Manufacturers must be relied up to Buy Best Electric Cables or Power Cables.
