Center SST OPGW cable is a kind of overhead grounding wire which take SST optical unit as the center, concentric stranding the ACS wires at outer layer according to certain lay ratio. It is widely used in modern information electric power system.

Structure characteristics and application

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
