Dry-type mine explosion-proof dry-type transformer

Features of Products

 The KBSG series mininq explosion isolation dry transforrner conforrns 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 offway 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. aprimary voltage is 6 kVs or 10 kVs, andneuterqender 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.
