Applications
Overhead Cable Wires is also known as covered line wire AAC(Aluminum Conductor) with XLPE insulation. Its mainly applications are:
● Crossing of telecommunication lines to guard against contact;
● Proximities to telecommunication lines to guard against contact;
● Lines (particularly service lines) accessible from buildings.

Details
The XLPE&HDPE - covered conductors have been developed primarily to give protection to telecommunication lines which are crossed by power lines and to give protection to the public from low voltage lines in case of accidental contact for short periods.The XLPE&HDPE - covered power lines have also been found useful in corrosive atmospheres and for preventing faults due to birds and trees. The conductors are sometimes referred to as”Wheather-Resistant Line Wire” and may consist of a single solid wire, or all aluminum stranded conductors (AAC) over which a covering has been applied.
