Stranded Stainless Steel Tube OPGW

Application

OPGW cables are used power transmission, communication, and lightning protection. It could replace traditional static / shield / earth wires on overhead transmission lines and add benefit of 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.

Description

The stainless steel tube is stranded by double or three layers of aluminium clad steel wires(ACS) or mix ACS wires and aluminium alloy wires.

Main Characteristics

● Larger cable diameter and much more fiber count.
● Larger tensile strength and fault current capacity to reach a better balance of electrical and mechanical performance.
● The amount of Stainless Steel Tube could be 1, 2 or 3 (max. at present).
● Optimum stranding design to reach a suitable secondary fiber excess length.
● The stranded layers could be double layers or three layers, the stranded wires could be AS wires with/or AA and Al wires.
