OPGW optical ground wire cable with layer stranding stainless steel tube type

OPGW optical ground wire  cable  with layer stranding stainless steel tube type

 Overhead Ground Wire OPGW Cable 

Features and advantage:

1. Replace existing aerial ground wires, upgrading communication lines of power systems.

2. Synchronous plan and design with ground wire when new aerial power lines are to be constructed

3. Provide stainless tube fiber unit with optimal protection

4. Conduct large fault short-circuit current and providing lightning protection

5. Suitable for application in hih fiber count and super high voltage power lines

6. Match with favorable tension-sag of the diffluent grond wire.

Product structure:

1. The stainless steel tube fiber unit is placed inan eccentric position and stranded together with Al-clad steel wires or Al-alloy wires simultaneously.

2. The Al-clad steel wires being placed in the inner layer can avoid rusting, and have high reliability and long life

3. Optimum stranding design makes secondary fiber excess length available

4. Good flexure and crush resistance

5. Provide high mechanical strength and large short-circuit current capacity

6. Obtain the best balance of electric and mechanic perfomance by adjusting AA/AS combination.

OPGW application:

1. Extremely corrosion areas, such as littoral, chemical areas

2. High lightning area, possible to still have relatively small overall diameter when using wires of bigger diameter on the outer layer

OPGW standard compliance:
