Optical Fiber Composite Ground Wire 12 Core Single Mode Uni-Tube Aerial Opgw Cable


Description:

OPGW is a type of cable structure with composite of optical transmission and overhead ground wire for power transmission. Its working in power transmission line both as optical fiber cable and overhead ground wire which can provide protection of lightning strike and conducting short circuit currency.The OPGW consist of stainless steel tube optical unit, aluminum cladding steel wire, aluminum alloy wire. It has central stainless steel tube structure and layer stranding structure. We can design the structure according to different environment condition and customers requirements.


Application:

Optical fiber composite ground wire [OPGW] is suitable for installation on new power lines with double function of ground wire and communication. Especially for installation on normal voitage and extra high voltage power lines. OPGW can replace conventional ground wire of old power line with increasing fiber communication function. They conduct short circuit current and provide lightning resistance.


Features:

1. Up to 144 fibers

2. Cable diameter and weight approximate with another ground wire. Less additional load to tower, high tensile strength.

3. Excellent stainless steel tube stranding technology make the fibers have good secondary excess length and allow the fibers free movement in the tube. Which keeps the fiber stress-free while the cable is subjected to longitudinal stress.

4. Optical fibers are protected by stainless steel tubes.

5. Excellent security, good bullet resist performance.

6. ACSW, AAW and SST stranded design provide wide range combination of electrical conductivity and mechanical tensile strength.
