Features of Products

The KBSG series mining explosion isolation dry transformer conforms to new GB 8286 mineral product separates explode migration transformer substation requests. Insulating the material adopts C class or H class to insulate, hot stability good  cooling off way a doption ANAN  be applicable to there are air and coal dust of the methane mixture  and there is the mineral well  mineral mountain  tunnel of explosion danger etc. environment, also be app licable to shortage with air and steam environment which decays metals and breakage to insulate.Settle the frequency as 50 Hz ,  a primary voltage is 6 kVs or 10 kVs,  andneuter gender not to connect ground for the power system,  for use various motive equipments in the environment with various use electricity device to provide power supply.
