Fiber Hope optical fiber communication expert & fiber optic cable manufacturer
Stranding stainless steel tube OPGW cable is cable product that produced by way of comprehensive stranding the aluminium clad steel wires and stainless steel tube optical unit which replaced one or some of aluminium clad steel wires of traditional ground wire cable. It realized the function of optical fiber communication and has bigger diameter and more optical fiber compared with center stainless steel tube OPGW.
·Big diameter and more optical fiber
·Big tensile strength and short-circuit current capacity, arrive the best balance of mechanical and electrical properties
·One or more optical units
·Best design of strand, obtain secondary optical fiber extra length
·Two or three layers of stranding wires, the wire can be aluminium clad steel wire or the combination of aluminium alloy wire and aluminium wire

OPGW optical cable is mainly used on 500KV, 220KV, 110KV voltage level lines.
Affected by factors such as power outages and safety of the line, it is mostly used on new lines
