Chongqing optical cable Wuxi Foshan corrosion-resistant single-mode overhead 36 core OPGW power composite optical cable manufacturer direct sales

Description :

　　OPGW optical cables can adopt aluminum tube type, aluminum skeleton type, and (stainless) steel tube type structures according to user needs. The optical fibers are sheathed in stainless steel sleeves, surrounded by aluminum clad steel wire (AS wire) and wrapped with aluminum alloy wire (AA wire) layers to form cables. OPGW optical cable, as a carrier of power communication, has been widely used in power communication systems both domestically and internationally, and OPGW optical cable technology is constantly innovating. The application of optical fiber composite overhead ground wire (OPGW) in power systems is becoming increasingly widespread, and its quality requirements are also increasing. As a power optical cable, various process controls in the production process of OPGW are becoming increasingly refined. As the core component of OPGW optical cable, the quality of stainless steel tube optical unit will directly determine the performance of OPGW optical cable.

　　feature

　　(1) Lines with high voltage exceeding 110kV have a large span (generally 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, as power outage losses are significant. Therefore, 0PGW should be used in the construction of new high-voltage lines above 110kV.

　　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.
