OPGW

Overhead ground wire is a metal wire installed parallel to a leading wire on top of a conductor in order to protect overhead transmission lines from lightning.
OPGW(Optical Fiber Composite Overhead Ground Wire) is made by adding optical fiber to the existing overhead ground wire to have it also be a telecommunication line. It is currently installed on many aerial lines throughout the globe.

Product Features

​

  • Multi-core Cable

       The multi-core (up to 144 cores), which is difficult to achieve in general OPGW, enables large-capacity information         

       transmission.

 

  • Design Variations

       Various specifications such as tensile load, cable weight and ground wire etc. can be custom configured according to

       each application by specifying different structures and materials.

 

  • High Reliability

       With optical fiber built into a flexible stainless steel loose tube (SSLT), this product has excellent tensile strength and is

       very stable against temperature fluctuations. Constructed with both SSLT and Al, the result is a structure that withstands

       external impact better than general OPGW.

 

  • Convenient Installation

       Installation is safe as it requires few rotations. Laid on existing aerial lines, this product is economical as it does not require

       a separate construction process.
