Dry Type Mining Explosion Isolation Movable Transformer Substation

Description

Features of Products
The mineral product separates the explode migration transformer substation separates the explode migration transformer substation by the mineral product with the do-like transformer. the high-pressured load switch either the high pressure and the low pressure switch or the low pressure guarantees is composed. Has the leakage. the leakage, the overload, short-circuits, the performance.
KBSGZY series dry type mining explosion isolation movable transformer substation iS a kind of movable whole set distribution and transformation device. It is suitable for not only mines filled with firedamp mixed gas, grime and explosive gas, but also the gas and steam environment that can not erode metal and insulation.
