KTPP
Complete transformer substation
of industrial type KTPP
The complete transformer substations of industrial design (KTPP) are intended for receiving, converting and distributing electricity of alternating current 50Hz, with voltage of 6 (10) kV to voltage of 0.4 kV. KTPP are applied to power supply of consumers in the industry, at gas-compressor stations, etc. They are manufactured with capacities from 250 to 2500 kVA.
