Save the city underpass power transmission capacity 220KV2500 square millimeter of cross-section of the nation's largest capacity cable successfully put into operation in Wuxi 220KV Yangtze change to Meili change line. July 7 expert on this cable inspection test and put into operation a week, reliable operation to meet the design requirements.

    220KV2500 mm square cross-section cable is the largest cross-section of the domestic application of the cable, the cable also use this grade was less, only in Jiangsu Province, Nanjing application. This cable has a section ampacity, weight, and difficult to bend, so much larger than the difficulty of the general construction of small cross-section cable.
