Switchgear K-104

Middle-voltage K-104 series switchgear, rated voltage 6 - 10 kV, is designed to receive and distribute electric power of three-phase alternating current with frequency 50 Hz in networks with insulated or earthed neutral.
They are used in various installations, including
- Enclosed switchgear in complete substations (CTS);
- Electrical substations in industrial plants;
- Distribution equipment for internal use in power stations;
- Utilities and other power supply facilities.
K-104 series switchgear consists of separate compartments with built-in equipment, measuring devices, relay protection, automation, signalling and control, interconnected in accordance with the electrical diagram of the main circuits of the switchgear.
The connections (inputs or outputs) can be either cable or busbar.
The design of the K-104 switchgear provides for three variants of entry of the high voltage cable into the high voltage compartment, depending on the specific project:
- from the bottom of the cable compartment (in the nomenclature, the cubicle number is followed by the letter "A"),
- at the top of the busbar compartment (in the nomenclature, the cubicle number is followed by the letter "B"),
- at the bottom outside the enclosure (in the nomenclature, the cubicle number is followed by the letter "C"),
The construction of the enclosure allows the connection of a maximum of four high-voltage cables with a cross-section of 3x240 mm2. In this case, if four cables are connected in the unit from the bottom, it is necessary to place units with no more than two cables on the left and right of the unit.
K-104 enclosures are designed for double-sided operation.
The K-104 enclosures are standardised and, regardless of the electrical connection schemes of the main circuits, have a similar design of the main components and the same overall dimensions. The exception is the cable inlet (outlet) boxes (option of cable inlet into the high voltage compartment from the bottom or top of the box), the depth of these boxes is 170 mm more than other unit.

Technical data

We offer you documentation for the manufacture of switchgear K-104:

- Preliminary technical documentation for participation in tenders for the manufacture of switchgear K-104. 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.
