YOFC Successfully Won The Bid For The 2021 Power Transmission And Transformation Project Of The State Grid Corporation of China
Recently, the eighteenth batch of purchases by the State Grid Corporation of China in 2021 (the second tender purchase of line equipment for power transmission and transformation projects) and the twentieth batch of purchases (the first 35-330 kV material agreement inventory for power transmission and transformation projects Bidding and procurement) The announcement of the successful bidders ended, and YOFC successfully won the bid. This is the first time that YOFC OPGW and other optical cables have won the bid for the centralized procurement project of State Grid Corporation of China, and it is also the unit with the largest amount of money won in the centralized procurement.
In 2021, the new infrastructure is in full swing, and the construction of UHV projects is intensified. Traditional communication lines are difficult to adapt to the development requirements of the new era. In response to the development needs of integrated, broadband, digital, multimedia, and computerized power communications, OPGW optical cables have appeared. OPGW optical cable utilizes the existing tower resources to give full play to the dual role of communication optical cable and ground wire, which not only supports and promotes the development of power communication networks, but also brings significant social and economic benefits.
OPGW is an overhead ground wire containing optical fiber with multiple functions such as overhead ground wire and optical communication. It is mainly used for 35kV, 110kV, 220kV, 500kV, 700kV, 1000kV and communication lines for newly built overhead high-voltage transmission systems. It can also be used to replace old The existing ground wire of the overhead high-voltage power transmission system adds optical communication lines to shunt short-circuit current and provide protection against lightning strikes.
