Center Stainless Steel Tube OPGW Cable

Small diameter and light weight, small short-circuit current capacity

Optical unit forms appropriate primary optical fiber extra length

Characteristics of tension resistance,torsion resistance and side pressure resistance are not good enough

Suitable for matching with GJ-35、GJ-50、GJ-70
