Description :
OPGW fiber optic cable manufacturer OPGW power communication fiber optic cable
OPGW optical cable, also known as Optical Fiber Composite Overhead Ground Wire.
Placing optical fibers in the ground wire of overhead high-voltage transmission lines to form an optical fiber communication network on the transmission lines, this structural form combines the dual functions of ground wire and communication, and is generally referred to as OPGW optical cable.

Product Structure:
OPGW optical cables are mainly used on 500KV, 220KV, and 110KV voltage level lines. Due to factors such as power outages and safety, they are often applied on newly built lines.
Product Features:
Small outer diameter, light weight, and no additional load on the tower.
The calculated fracture strength is high and can withstand the test of harsh environments.
Can accommodate 2-72 core single-mode/multi-mode optical fibers or a combination of single-mode and multi-mode optical fibers.
G.652 fiber optic, G.655 fiber optic, or a combination of both can be used.
Reasonable structural design ensures that the optical fiber operates without strain under normal operating conditions.
The applicable characteristics of OPGW are:
(1) Lines with high voltage exceeding 110kV have a large span (usually above 250M);
(2) Easy to maintain, easy to solve for line crossing problems, and its mechanical characteristics can meet the requirements for large line crossings;
(3) The outer layer of OPGW is metal armor, which has no effect on high-voltage corrosion and degradation;
(4) OPGW must be powered off during construction, and the losses caused by power outages are significant. Therefore, OPGW should be used in the construction of new high-voltage lines above 110kV;
(5) In the performance indicators of OPGW, the larger the short-circuit current, the more it is necessary to use good conductors for armor, which correspondingly reduces the tensile strength. However, in the case of a certain tensile strength, the only way to increase the short-circuit current capacity is to increase the metal cross-sectional area.
