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. It has creepage, creepage closedown, overload, short-circuits, overvoltage and so on protection feature.
