Stranding Stainless Steel Tube OPGW Cable

STANDARD:IEC 61232-1993 GB/T 17937-2009 IEC 60104-1987 GB/T 23308-2009 GB/T 3955-2009 IEC 60794-4-10 IEEE 1138-1994 DL/T 832-2003 ITU-T G
VOLTAGE:
CAPACITY:2000 km/month

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
