The transformer station type RKS10-4U is a device designed for use in underground mining in excavations with no explosion hazard or in conditions with no methane explosion hazard and designated as class A coal dust explosion hazard.
Switchgear type RKS10-4U is designed for connecting and switching on receivers in the 3-phase mine grid with insulated star point on the transformer (system IT) of rated grid voltage of 1000V.
Receivers are being connected to the switchgear via buried socket or terminal strip via cable glands.
The switchgear is equipped with electrical power protections against short-circuiting, overloading (option), low insulation resistance and an increase in earth resistance.
