Complete switchgear K 47, K 59
Complete switchgears of the K-59 type are designed for receiving and distributing electric energy of alternating three-phase current of industrial frequency 50 and 60 Hz with a voltage of 6 and 10 kV in block substations for industrial facilities, oil fields, etc.
Complete switchgears are designed to operate under the following conditions:
- altitude above sea level-up to 1000 m;
Ambient air temperature:
- for the performance of U1 not higher than +40 S and not lower than -40 S (occasionally -45 S);
- for the CHL1 version – not higher than +40 S and not lower than -60 S.
