TAP CHANGER sare intended for switching (regulation) of the power supply
electric voltage of 6-10 kV. in power oil transformers with a capacity of 25
up to 1600 kVA.
TAP CHANGER switches are used (work) only for switching electric
transformer voltage with disconnected electric load (voltage)
transformer, i.e. with the voltage regulation circuit – “ПБВ” (Switching without
excitement).
TAP CHANGER switches should only work in transformer oil environments, all
The materials used in the TAP CHANGER switches are oil- and heat-resistant.

TAP CHANGER switches are used in transformers of suitable power,
voltage and connection diagrams depending on the maximum permissible load current
to the current-carrying contacts of the switch and the number of contacts that should
correspond to the number of regulatory taps of the transformer windings. Landing and
overall dimensions of the switches are selected by the customer:
