Description

OPGW cable is the short form of Optical Fiber Composite Overhead Ground Wire.

OPGW cable is suit for installation on new power lines with double function of ground wire and communication,

especially for installation on normal voltage and extra high voltage power lines. OPGW can replace

conventional ground wire of old power lines with increasing fiber communications function.

OPGW cables conduct short circuit current and provide lighting resistance.
OPGW cables are usually two structures. The central tube OPGW cable can obtain maximum

optical fiber excess length in a smallest steel tube. The diameter of stainless steel tube is

bigger than that of ACSR wire and aluminum alloy wire. The stainless steel tube is placed in the

center of the stranded structure of the OPGW cable. Stranded OPGW cable can obtain secondary excess length;

the diameter of stainless steel tube is consistent with diameter of aluminum alloy wire.

Application:
the 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.
