Long Distance Loose Tube OPGW Cable 24 Core Optical Power Ground Wire Optical Fiber Cable
OPGW optical cable combines optical fiber and copper wire (or other metal wire) together. It can transmit both optical signals and power. OPGW optical cable is suitable for long-distance communication transmission occasions. OPGW optical cable has low fiber transmission loss, which can ensure the stability and reliability of communication signals during long-distance transmission.
The No.T-FC052 fiber optic composite overhead ground wire (OPGW) is a type of overhead ground wire containing optical fibers, which has multiple functions such as overhead ground wire and optical communication. Optical power ground wire is mainly used for communication lines in 110kV, 220kV, 500kV, 750kV, and new overhead high-voltage transmission systems. It can also be used to replace the existing ground wire of old overhead high-voltage transmission systems, add optical communication lines, conduct short-circuit currents, and provide lightning protection. Special structures can be customized according to user needs.
Product Feature
1.Stainless steel tube protects optical fibers with high tensile strength;
2.Small optical fiber composite cable diameter, light weight, and low additional load on the tower;
3.The optical unit forms a suitable excess length of primary optical fiber;
4.Slightly poor performance in terms of tensile resistance, torque resistance, and lateral pressure resistance;
Product Application
1. Communication lines in high-voltage transmission systems;
2. As an overhead ground wire, OPGW has all the functions of a traditional ground wire, including lightning protection, short-circuit current transmission, and mechanical support for the line. It can provide the necessary grounding protection for power lines and ensure the safe and stable operation of the power system.
