Stranding Stainless Steel Tube OPGW Cable

Description:

Big diameter and more optical fiber 

Big tensile strength and short-circuit current capacity, arrive the best balance of machanical and electrical properties

One or more optical unit

Best design of stranding, obtain secondary optical fiber extra length

Strands plies can be two or three, the wire can be ACS wire and/or the combination of aluminium alloy wire and aluminium wire
