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.

We offer You documentation for the manufacture of switchgear 20 kV K-203:

- Preliminary technical documentation for participation in tenders for the manufacture of switchgear 20 kV K-203. We will prepare for you the necessary information to assess the possibility of manufacturing products in accordance with the requirements of tender documentation and questionnaires.
- Working drawings, 3-D models, and other necessary documentation for the manufacture of switchgear 20 kV K-203 at your enterprise. If you do not plan to independently manufacture components and parts of the product, we will help you place their production at third-party enterprises. General assembly of the product and installation will be carried out at your enterprise.
- All documentation, if necessary, is adjusted in accordance with the requirements of the project, as well as in accordance with the technological capabilities of your enterprise.
- If equipment from another manufacturer is installed at the substation, we will prepare for you documentation for the manufacture of similar equipment in addition to the installed one

Advantages of working with us:

- You do not need to employ highly qualified engineers - You receive a set of documentation for the product being manufactured, which can be operated by a semi-skilled engineer.
- You do not need to manufacture prototypes of products - our experience allows us to successfully launch serial batches of products for production.
- Working according to our documentation - your specialists will receive advice on all the nuances of manufacturing switchgear 20 kV K-203.
