Complete transformer substations

A wide selection of complete transformer substations from the manufacturer. We manufacture to order KRPZ, complete distribution devices, (KTP) Complete transformer substations with a voltage of 10/0.4 kV, 35/0.4 kV, 35/10 kV, 20/0.4 kV. Affordable prices. Quality guarantee. Delivery across Ukraine.The complete transformer substation (KTP) is designed for reception, transformation and distribution of electrical energy of three-phase alternating current with a frequency of 50Hz in systems with a deaf-grounded transformer neutral on the lower voltage side in rural electrical networks. KTP are produced at voltages of 6 and 10 kV, with a capacity of 25 kVA and above. To determine the price of a substation, and before buying a substation, you need to understand the internal configuration, from which the final cost and purpose of the transformer substation will be based.
Complete transformer substations of this type are manufactured in a general industrial design and are equipped with oil or dry power transformers with a capacity of 25, 40, 63, 100, 160, 250, 400, 630 kVA and higher, at a voltage of 0.4 kV, 6, kV, 10 kV, 35 kV, three-phase alternating current with a frequency of 50 Hz. In general, there are mobile, single-transformer substations of outdoor installation, kiosk, dead-end type with cable or air input. They are produced both with a blindly grounded neutral and with an isolated neutral.

Transformer substations have the following components:
— the compartment of the distribution device on the side of the higher voltage of the PVN;
— power transformer compartment;
— compartment of the distribution device on the lower voltage side of the substation.

The PVN compartment includes:
— disconnector or load switch; — high-voltage fuses PKT-6(10) kV;
— high-voltage arresters RVO-6(10) kV.

The power transformer compartment includes:
— a power transformer (with a nominal capacity of 100 ... 630 kVA), according to the Customer's application.

The RPNN section includes:
— input circuit breaker up to 630 (1000) A;
— outgoing consumer lines in the amount of up to 6 units with automatic switches;
— leakage current monitoring relay RU-380 (UAKI);
— block of general electricity accounting (at the request of the Customer);
— automatic switching on of feeder lines (using starters).

The substation provides:
— protection of the integrity of the grounding circuit of outgoing lines;
— connection of external lighting with protection against short circuit (at the request of the Customer);
— control of the insulation resistance both under the voltage of the outgoing connections and in the disconnected state.
