  •  Sun Telecom'OPGW cable is a type of cable structure with an optical transmission composite and overhead ground wire for power transmission. It works in power transmission lines both as optical fiber cable and overhead ground wire which can provide protection of lightning strike and short circuit currency conduction.

    The OPGW consists of stainless steel tube optical unit, aluminium cladding steel wire and aluminum alloy wire. It has layer stranding structure. We can design the structure according to different environment conditions and customer’s requirements.
