Length 2km 4-288core Optical Power Ground Wire

Optical fibre composite overhead ground wire (OPGW) is an overhead ground wire containing optical fibre. It has multiple functions such as overhead ground wire and optical communication. It is mainly used for communication lines of 110KV, 220KV, 500KV, 750KV and new overhead high-voltage transmission system. It can also be used to replace the existing ground lines of the old overhead high voltage transmission system, add the optical communication line, transmit short time current and provide anti lightning protection. Other structures can be customized on request.

Packing & Shipping

• Standard Cable Drum

• Standard reel length: 2/3km/reel, other length is also available

The OPGW shall be tightly and uniformly wound on a strong wood-iron reel which conforms to ANSI/AA 53-1981 or equal. The reel shall be lagged with stout wood-iron battens so as to prevent the OPGW from damage in ordinary shipping, handling, storage and stringing operations.

According to length of cable, we choose different type reel (D,d,b,w1,w2) for loading cable.
