Email1.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.
2. Lines with high voltage exceeding 110kv have a larger range (generally above 250M).
3. Easy to maintain, easy to solve the problem of line crossing, and its mechanical characteristics can meet the line of large crossing;
4. The outer layer of OPGW is metal armor, which does not affect high voltage electric corrosion and degradation.
5. 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).
