Central Stainless Steel Loose Tube OPGW Cable
Application
● OPGW optical cables are mainly used on 110KV, 220KV, 550KV voltage level lines, and are mostly used in newly-built lines due to factors such as line power outages and safety.
● Lines with high voltage exceeding 110kv have a larger range (generally above 250M).
● Easy to maintain, easy to solve the problem of line crossing, and its mechanical characteristics can meet the line of large crossing.
● The outer layer of OPGW is metal armor, which does not affect high voltage electric corrosion and degradation.
● OPGW must be powered off during construction, and the power loss is relatively large, so OPGW should be used in newly built high-voltage lines above 110kv.
Main Features
● Small cable diameter, light weight, low additional load to the tower.
● The steel tube locates at the center of the cable, no second mechanical fatigue damage.
● Low resistance to side pressure, torsion and tensile (single layer).
