KBSG mine flameproof 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. lnsulating the materal adopts C class or H class to insulate, hot stablity good, cooling offiway a doption ANAN,be applicble to there are air and coaldust of the methane mixture, and there is the mineral well, mineral mountain,tunnel of explosion dangeretc. environment.also be applicable to shortage with air and steam environment which decays metals and breakage to insulate. Settle thefrequency as 50 Hz.aprimary voltage is 6 ks or 10 k's, andneuterqender not to connect ground for the power system,for use various motiveequipments in the environment with various use electricity device to provide power supply.
