Optical Fiber Composite Optical Ground Wire OPGW Cable (Central Tube Type)

Product introduction

OPGW optical ground wire, also called fiber optic composite overhead ground wire, places optical fibers in the ground wire of overhead high-voltage transmission lines to form a fiber optic communication network on the transmission lines. This structural form has dual functions of spacing between ground wires and communication.

The central tube type OPGW optical cable adopts a design where stainless steel tube fiber units are twisted together with other metal wires. The fiber is placed inside the stainless steel tube to obtain better surplus length, ensuring the electrical performance, mechanical and physical properties, and thermal stability of the optical cable.

Product Feature 

•Adopting advanced stainless steel tube production technology, the tube is filled with water-resistant compounds, which can effectively protect the optical fiber;

•Combining the dual functions of ground wire and communication optical cable, eliminating the huge cost of repeated installation and maintenance;

•Installed on the top of power overhead line towers, without considering factors such as optimal hanging points and electrical corrosion;

•During the renovation process of the old line, the outer diameter and tensile strength of the optical cable are better matched than pulling another ground wire;

•Large transmission capacity, high communication quality, good reliability, and superior mechanical and electrical performance.
