OPGW products integrate the functions of a ground wire and an optical communication link. They are primarily used for communication lines in new overhead high-voltage transmission systems (spanning voltage levels from 35kV to 750kV and above) and for retrofitting existing systems by replacing old ground wires to add optical communication capabilities; they also conduct short-circuit currents and provide lightning protection. Our company scientifically designs the optical cable structure based on specific operating conditions—such as tower spacing, sag requirements, ice and wind loads, allowable suspension point tension, communication capacity, and short-circuit current—or we can manufacture cables according to user-specified designs.
