Hebei Qinhuangdao OPGW optical cable power composite ground wire outdoor optical cable overhead OPGW optical cable

Description :

　　Product usage: Due to factors such as power outages and safety concerns, it is commonly used on newly constructed power lines.

　　Product Description: The structure of 24 core OPGW optical cable (Optical Fiber Composite Overhead Ground Wire, also known as Fiber Composite Overhead Ground Wire) generally adopts aluminum tube type, aluminum skeleton type, and (stainless) steel tube type structure. The structure of OPGW optical cable is to put 250 μ m optical fiber into a stainless steel sleeve, wrap aluminum clad steel wire (AS wire) around the sleeve, and wrap aluminum alloy wire (AA wire) layer on the outer layer to form a cable.

　　Product application: 1. Lines with high voltage exceeding 110kV and 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, 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. OPGW optical cables are mainly used on 110KV, 220KV, and 550KV voltage level lines, and are affected by factors such as power outages and safety

　　Sound, mostly applied on newly built lines.

　　Performance characteristics: 1. Good compactness and high tensile strength;

　　2. Short circuit current causes minimal mutual interference between the power grid and communication network;

　　3. The excess length of the optical fiber and the twisted pitch of the cable core ensure that the OPGW optical cable is not subjected to force during operation tension;

　　4. Similar to commonly used ground wire specifications, it is very convenient to install and can directly replace the original ground wire;

　　5. The stainless steel tube production technology used is filled with water-resistant compounds inside the tube, which can effectively protect the optical fiber.
