Switchgear 20 kV K-203
Middle-voltage 20kV K-203 switchgear are used for reception and distribution of electric energy of three-phase alternating current with frequency of 50 Hz in networks with insulated or earthed neutral.
K-203 switchgear are used in:
- enclosed switchgear of complete transformer substations (KTP);
- industrial substations;
- auxiliary switchgear of power plants;
- and other power supply facilities.
K-203 20kV switchgear K-203 are installed both in capital buildings of switchgear stations and in special quickly assembled modules of full factory readiness.
The K-203 20kV switchgear is made of steel with aluzinc coating and is divided into insulated compartments, each of which is equipped with a separate overpressure relief duct, which ensures the localisation of personnel in the event of an internal arcing fault;
Safety of operation of K-203 switchgear is ensured by a system of built-in mechanical and electromechanical interlocks in accordance with GOST and PUE requirements;
Ease of assembly, installation and adjustment is ensured by convenient access to the mounting points of K-203 switchgear, cable and busbar connections;
Secondary circuits are laid in insulated metal cable ducts, which ensures their protection and high noise immunity;
Wide standardisation of K-203 switchgear components ensures their adaptation and modernisation in accordance with the requirements of the design documentation.
