KBSGZY series mining flameproof movable substations is a kind ofmovable whole set for power supply and transformer. It is suit mines filled with firedamp mixed gas, grime and explosive gas, the gas and steam environment that can not erode metal or destroy insulation as well.
The mining product separates the explode migration transformer substation separate the explode migration transformer subsation by the minwral product with the do-like transformer, the high-pressured load switch either the high pressure and the low pressure switch or the low pressure guarantes is composed. Has the leakage, the leakage, the overload, short-circuits, the performance.
