220 kV Xiaochang 4R19 line, Xiaozhou 4R20 line is the most important "lifeline" of Zhoushan Electric Power. Since it was put into operation, it has successively passed through "Plum Blossom", "Sea Anemone" super typhoon and rain and snow freezing disaster, The impact of the big cat mountain tower surface coating oxidation, shedding serious. In order to better ensure the safety of Lifeline, operate steadily and improve the service life of equipment, the power transmission equipment group decided to replace the 49 # tower in Xiaochang 4R19 line and Xiaozhou 4R20 line with surface rust treatment and paint protection To reduce or prevent the generation of corrosion.

    July 1, 2010, 220 kV Zhoushan and the mainland network project was put into operation, Zhoushan and the mainland added a maximum transmission capacity of 600,000 kilowatts of power grid "lifeline", a total length of 37.38 km, a total of 87 towers. Among them, a large span of Cats Mountains hit a number of major firsts: the tower is 370 meters high and weighs 6,000 tons, both of which are the largest in the world; the first one is 6.2 km long across the country and the second one is 2756 meters long spanning the long span. Zhoushan Power Grid has thus achieved a historic leap from 110 kV to 220 kV. The overall project is expected to be completed by the end of this month.
