3-120- [145;73] is Optical Fibre Composite Overhead Ground Wire (Stranded-tube) Optical fibre composite overhead ground wire (OPGW) is an overhead ground wire containing optical fibre. It is mainly used for. OPGW-36B1., Ltd, which locates at Wendeng District, Weihai City, Shandong Province of China, was eatablished in 1985. It has 1500 empolyees and total assets is over 1. It covers an area of 2 million square meters,construction area is 0. 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. The phosphide coating of phosphated steel wire can provide good lubrication and corrosion resistance, which can reduce the friction and wear of steel wire in the process of use, reduce energy loss and prolong the service life.
