Switchgear 35kV VM-4

Switchgear of the series VM-4 for voltage 35 kV are used for receiving and distributing three-phase alternating current electricity with a frequency of 50 Hz in networks with an isolated or grounded neutral.
Switchgear 35 kV VM-4 are used in:
- indoor switchgear units (ISU) of complete transformer substations (CTS);
- electrical substations of industrial enterprises;
- switchgear of power plants' own needs;
- public utility facilities;
- and other power supply facilities.
Switchgear 35 kV VM-4 are installed both in permanent buildings of indoor switchgear units and in special quickly-mounted modules of full factory readiness.
The housing of the switchgear 35 kV VM-4 is made of steel with a polymer coating, and is divided into compartments isolated from each other, each of which is equipped with a separate channel for releasing excess pressure, which provides localized protection of personnel in case of internal arc short circuits.
The operational safety of the switchgear 35 kV VM-4 is ensured by a system of built-in mechanical and electromechanical interlocks in accordance with the requirements of IEC.
Simplicity of assembly, installation and commissioning is ensured by convenient access to the mounting points of switchgear 35 kV VM-4, cable and busbar connections.
Secondary switching circuits are laid in insulated metal cable ducts, ensuring their protection and high noise immunity;
The wide unification of the components of the switchgear 35 kV VM-4 ensures their adaptation and modernization in accordance with the requirements of the project documentation.
