3 Layer Stranded OPGW Optical Fiber Composite Overhead Ground Wire ACS
The OPGW fiber optical cable's Aluminum tube is surrounded by single or double layers of aluminum clad steelwires(ACS)or mix ACS wires and aluminum alloy wires Aluminum wires / Aluminum alloy wires Optical fibers. Aluminum fiber optical cable's have the dual functions performance functions of phase conductors with communication capabilities.
Application
OPGW optical cable is mainly used on 500KV, 220KV and 110KV voltage level lines. It is mostly used on new lines due to the influence of line power outage and safety.
The applicable characteristics of OPGW are:
(1) The line with high voltage exceeding 110kv has a large gear distance (generally above 250M);
(2) Easy to maintain, easy to solve the problem of line crossing, its mechanical characteristics can meet the large line crossing;
(3) The outer layer of OPGW is metal armor, which has no effect on high voltage electrical corrosion and degradation;
(4) OPGW must be powered off during construction, and the power loss is large, so OPGW should be used in new high-voltage lines above 110kv;
