MV-4 series complete aisle-type switchgears for outdoor installation are intensively used in modern advanced medium voltage secondary distribution systems.

Prefabricated panels, connected to each other by bus bars allow minimizing time for installation and commissioning.

MV-4 is an analog of cubicle of K-59 series and can be docked also to K-37 and K-13 (K-XIII) series ones.

Aisle-type construction improves working conditions of stuff and safety level, making possible installation of thermal insulation, heating and forced ventilation for year-round service in various climate zones.

Metal-clad enclosure of MV-4 is subdivided by grounded partitions into four compartments:

  • Cable compartment;
  • Low voltage compartment;
  • Bus bar compartment;
  • Circuit breaker compartment.

Circuit breakers are mounted on kart for providing visible circuit breaking. All live parts are shielded by shutters when withdrawable element moves into control and service position.

Front and rear parts of switchgear are equipped by two doors for maintenance purposes.
