Brief description of substation design and operational principle
Structurally, KTPK is designed as a kiosk module and has a prefabricated welded structure. The design is intended for installation of a three-phase power two-winding transformer TM, TMG. Automatic switches (with fuses) are installed in the low-voltage switchgear to protect the outgoing lines. The transformer compartment has swing doors on both sides to access the compartment and to mount or to dismount the transformer.
