In this system an all-dielectric optical cable is lashed to an overhead wire or elecrical conductor with a series of clips or a special lashing tape.

Mobile Unit is used to deliver guide rope suspended with existing Overhead Ground Wire (OHGW) by self‐driven machine from one steel tower to the next steel tower using supporting roller system.

Recovery Machine used to recover the guide and pulling rope upon completion of installation of OPGW and retrieving the existing OHGW. It prevents of supporting rollers and tighten the guide rope to prevent touching with live conductor, it has a serving brake when the guide rope is being drawn back by the winch.

Grounding Roller is a two guide wheel block. It is used to protect workers from induction. Install after every 150 meters interval distance supporting rollers or minimum of two (2) pcs Grounding Rollers per span whichever is applicable.

Wire Stretching Roller is designed to smoothly guide and lessen friction during stringing works to prevent damage to the OPGW cable. This tool with 5 rollers can turn up to 90 deg and installed inside the steel tower.

Earthing Roller is designed to protect worker from possible electric induction from the existing live high voltage cable.
