Complete block modules of the KRU-BM-KEP series
KRU-BM is designed for setting up 0.4-10 kV distribution points for receiving and distributing electrical energy of three-phase alternating current with an industrial frequency of 50 Hz and medium-voltage transformer substations.
KRU-BM allows the installation of various options for complete switchgear, complete transformer substations, and electrical equipment for various purposes, as well as the organization of rooms for duty personnel. KRU-BM is characterized by high technical performance and ease of maintenance.
KRU-BM units are manufactured according to working engineering design documentation of the enterprise taking into account technical requirements of GOST 14693-90, GOST 22853-86, as well as SNiP 2.09.02-85, SNiP RK 2.02-05-2009 (regarding requirements for mobile prefabricated buildings). Electrical equipment in KRU-BM is installed in accordance with technical documentation for these products and safety requirements of GOST 12.2.007.4-96.
The application of KRU-BM makes it possible to increase the mobility and maneuverability of power supply systems, reduce the length of power transmission lines, and therefore increase protection reliability, as well as reduce construction and assembly work volume and commissioning deadlines for electrical equipment.
