Optical fiber composite overhead ground wire(OPGW)

Introduction

OPGW is mainly applied in communication line of newly constructed high voltage transmit electricity system with 35 KV or above, or replacement of existing ground wire of previous overhead high voltage transmit electricity system, adding of communication lines and conduction of short-circuit current or provision of anti-lightning protection.

Advantage

●Diameter of the cable is small with a low additional load to the pole and tower.

●Design of stainless steel tube is reasonable and excess lengths of the fiber is correct.

●Stainless steel tube protects the fiber with powerful tensile strength.

●Optical unit of the stainless steel tube is the interlayer of the cable and it can resist twist and has good lateral pressure performance.

●With good safety performance and strong shooting resistance performance, not easy to be stolen

●Different armor combinations or meeting different combinations of electrical and mechanical property.

●Standard：IEEE 1138

●Packing：Iron wooden drum
