Complete switchgears series 20 kV
Complete switchgears series 20 kV
Complete switchgears series 20 kV is an installation that receives and distributes electric power of 3-phase alternating current (frequency 60 and 50 Hz) for a rated voltage of 20 kV.
The design consists of several separate cabinets:
– switching devices;
– automation and protection devices;
– measuring instruments;
– Control block;
– alarm;
The units are designed for internal installation in spaces with temperature conditions from -25 °С to + 40 °С. The level of protection IP31 in accordance with ГОСТ 14254-96 allows the use of equipment in non-explosive, uncontaminated conditions. The units are actively used at power plants of various types, at distribution substations in the field of energy, industry, utilities and other power supply facilities
