Complete KRUN-10 kV external distributors
The complete distribution devices of an external installation of KRUN type are used for receiving and distributing the electrical energy of a three-phase alternating current at a frequency of 50 Hz, at distribution points 10 (6) kV and transformer substations 110/35/6-10kV; 35/6-10 kV.
The complete distribution devices of an external installation of the KRUN type are used for receiving and distributing the electrical energy of a three-phase alternating current at a frequency of 50 Hz, at distribution points 10 (6) kV and transformer substations 110/35/6-10kV; 35/6-10 kV.
The device consists of KRUN cabinets for various functional purposes which are interconnected, in which switching devices (fixed or shattered), measuring current transformers, voltage transformers and own needs are arranged; Relay sewing and automation and g.d. The degree of protection of the cells is 1P44 (34) by GOST 22789-94. A list of KRUN cells, single-line primary connections and installed equipment are given in the tables. KRUN is not intended for work in an environment subject to increased pollution, gases and vapours harmful to insulation, or hazardous to explosion and fire.
