common box enclosed insulated tubular bus
With the increase of substation capacity, the rated current of 10kV and 35kV bus of the main transformer keeps increasing (more than 3000A). The current distribution of conventional rectangular copper plate bus is not uniform, with large skin effect coefficient and increased heat loss, and the dynamic stability performance cannot meet the requirements of short-circuit current. GFGM series common box closed insulated tubular bus (3-35kV/ 1600-8000A) is a new type of closed insulated tubular bus developed and produced by our company according to the market demand. The product can replace the traditional closed insulated rectangular busbar in various properties and is applied in practical engineering. Busbar design, manufacturing, testing, installation and other processes by our company tracking services.
