APPLICATION
OPGW cables are used power transmission, communication, and lightning protection. It could replace traditional static / shield / earth wires on overhead transmission lines with containing optical fibers which can be used for telecommunications purposes. It is suitable for high-voltage/ultra-high-voltage lines in intercity or cross-country projects that need both communication and grounding functions over long distances.
Central Stainless Steel Tube OPGW applies to the transformation of old lines.
DESCRIPTION
The central stainless steel tube is surrounded by single or double layers of aluminium clad steel wires(ACS) or mix ACS wires and aluminium alloy wires.
MAIN CHARACTERISTICS
●Small cable diameter and short-circuit current capacity, light weight.
●The stainless steel tube can form a suitable primary fiber excess length.
●It has slightly worse tensile, torsion and crush resistance performance.
