OPGW 144 Strand Outdoor Fiber Optic Cable Composite Overhead Ground Wire
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.
Characteristics:
. bio-function of ground wire and communication cable, avoid a huge expenditure to re-erect and re-maintain;
. erect on top of power overhead line pole, need not to consider its best hanging point, electro-corrosion, and others.
. in the process of old line transformation, cable’s outer diameter and tension may be matched better than another ground wire;
. big transmission capacity, good and reliable communication;
excellent mechanical and electrical property;
Good security, long lifetime, and invulnerable to gun fire.
