6kv or 10kv Mining Flameproof Mobile Substation

Mining flameproof mobile substation is used in explosion risk mine of methane mixtures and coal dust, also, it is suitable for air and steam environment without corrosion and destroy insulation, which frequency is 50Hz and one side voltage is 6kv or 10kv. It is composed of explosion proof dry transformer, explosion proof high voltage switch board and explosion proof low voltage feed switch cabinet. The material of iron core of mining flameproof mobile substation is superior cold roll silicon steel sheet, full inclined non-punching structure. Insulation grade is C or H, and ANAN cooling.
