General Description

Medium voltage switchgear KRU-SESH-63 is dedicated to electrical energy receiving and distribution (3-phase, rated voltage 6(10) kV, rated current 630-2000 A, frequency 50/60 Hz).

KRU-SESH-63 Scope of Application:

  • Oil & Gas industry;
  • Mines Metals Minerals;
  • Electrical Utilities;
  • Industry;
  • Infrastructure;
  • Generation including Nuclear power plants;
  • Transportation including Railways.

As incoming and coupling cubicles with rated currents 2000-3150 A K-61M should be used.

Two solutions: with door and without door in VCB compartment.
VCB moving from working to test position only with closed door.
Any kinds of VCB and SF-6 CB can be installed as well as any kinds of relay protection.
Specific tropic solution (optionally).
