Description

Designed for three-phase power supply to electrical receivers, installed in underground coal, ore mines and other enterprises not hazardous with gas and dust explosion, as well as to provide protection against current leakage and overcurrent on low voltage lines.

Schematic solutions and components are maximally unified with KTPV-type substations.

KTPRN-type substations have less weight compared to KTPV-type substations due to optimal metal consumption reduction, without compromising the rigidity and structure strength.

Manufactured both in basic Corum Group version and in accordance with Customer’s technical requirements, providing an individual approach to each client.
