The complete switchgear for voltage up to 10 kV, type YAKNO-RB, is designed to receive and distribute electric power of three-phase alternating current with voltage up to 10 kV with frequency 50 Hz in quarry distribution networks with isolated neutral, as well as for protection of electric consumers from emergency modes of operation.
YAKNO-RB has the following protections: against short circuits in high-voltage circuits; maximum current protection; against single-phase earth faults; against minimum voltage; against breakage of the cable earthing conductor; against atmospheric and switching overvoltages.
YAKNO-RB has all protective interlocks in accordance with the requirements of FSETAN normative documents and GOSTs.
