Environmental specifications:

The switchgears are intended for indoor operation with the following conditions to be met:

  • Maximum height above sea level: 1000 m
  • Seismic resistance: up to 9 points MSK-64 scale
  • Maximum ambient temperature: +45ºС
  • Minimum ambient temperature: -5ºС
  • Humidity: 98% RH at 25ºС
  • Atmosphere type: II as per GOST 15150-69 (Russian standard system)
  • Non-explosive environment free of current-conducting dust, aggressive vapour and gases that may damage insulation materials and metal parts

Switchgears can be used indoor with minimum temperature of -25ºС. If this is the case, the switchgears are equipped with anti condensation heater elements thus providing normal environmental conditions of the equipment enclosed in cabinets.

Switchgears can be installed in containers which have heating and ventilation system.

The switchgears are designed in accordance with GOST 14693-90, GOST 12.2.007.0-75, GOST 12.2.007.4-75 standards.
