These cables consist of a nucleus containing optical fibres and an armour generally composed of one or more layers of aluminium wire, aluminium-magnesium-silicon alloy wire, steel wire or aluminium-coated steel wire. development of communities. With this in mind, we provide major global organisations in multiple industries with best-in-class products and services, based on installation and operation. In economic terms, that means no unexpected costs due to on-site delays, professional project management. At the top of high-voltage transmission lines, a special optical cable integrating dual functions is silently supporting the stable operation of the energy network – this is the OPGW optical cable (optical fiber composite overhead ground wire). An OPGW cable contains a tubular structure with. An optical fiber composite overhead ground wire (OPGW) is a new type of ground cable used in the high-voltage power transmission system that serves as both a conventional overhead ground cable and a communication optical cable. Application OPGW is mainly applied in communication line of newly constructed high voltage transmit electricity system with 35 KV or above, or replacement of existing ground wire of previous overhead high voltage transmit electricity system.
