OPGW(Optical Ground Wire)
Description

Description:
     
OPGW provides ground wire protection for overheadpower lines as well as fiber optic cable for telecommunication network with high performance. By combining these functions inone cable, OPGW considerably reduces loads on the towers and is
optimized for superior mechanical, electrical, and data transmission properties to fulfill all overhead line design requirements
.

Feature / Benefit:
      Up to 144 fibers, 48 fibers
      Laser welded, hermetically sealed stainless steel tubes provide mechanical and thermal protection for optical fiber
      High tensile load, long span, high crush resistance
      Excellent resistance to moisture and hydrogen ingress handling
      Fiber bundles for more than 12 fibers to quick and easy identification
      Minimized additional loads due to small diameter and lightweight with the high strength aramid yarns
      Anti-rotational devices usually not required for installation
      Custom cable designs available
      Meets or exceeds test criteria specified in IEEE 1138, the recognized standard for OPGW
