Composite Cables / OPGW Composite Optical Cable
Fibre Optic Overhead Group Wire Optical Ground Wire (OPGW) is used in power utility for dual function as a ground or static wire and a path for transmission of voice, video or data signals through optical fibres allowing for fast, reliable and cost effective installations. Fibres are placed in a central stainless steel tube with water-resistant jelly filling; it is inserted into an aluminium pipe which provided added crush protection and increasing the conductivity. Over it one or two layers of aluminium coated steel wire or aluminium wire or aluminium alloy wire are stranded, stranded wires are selected to optimize mechanical and electrical properties of cable. They have high tensile load, long span and high crush resistance. Their small diameter and light weight minimize load to the tower.
