Complete transformer substations KTPU-1-25...2500/10(6)0.4 U1 (dead-end kiosk type)

COMPLETE TRANSFORMER SUBSTATIONS KTPU-1-25...2500/10(6)0.4 U1 (dead-end kiosk type)

Complete dead-end transformer substations - KTP-1 with a capacity of 25-630 kVA, HV voltage of 6 or 10 kV and PN voltage of 0.4 kV are designed for receiving, converting and distributing three-phase alternating current electrical energy with a frequency of 50 Hz in systems with a dead-earthed neutral of the transformer on the low-voltage side. KTP-1 are designed for power supply of agricultural, industrial consumers, individual settlements and small industrial facilities in areas with a temperate climate (from -45 ° C to +40 ° C). KTP-1 is installed on the simplest concrete platform.

Type of climatic design U1 according to GOST15150.

Normal operation of the KTP is ensured under the following conditions:

1. Altitude above sea level - no more than 1000 m;

2. Environment - non-explosive, not containing conductive dust, aggressive gases and vapors in concentrations that reduce the KTP parameters to unacceptable limits;

3. Wind speed up to 36 m/s (wind pressure speed up to 800 Pa);

4. Atmosphere type - II according to GOST 15150.

High-voltage input - air or cable, outgoing line outlets - air or cable.

Dead-end KTP-1 are manufactured as single-transformer and double-transformer (with high and low voltage sectioning).

Circuit breakers are installed on the PN side. Their number and rated current are given in the table.

The KTP delivery set includes UVN (air inlet) and RUNN cabinets, power transformer, external installation disconnector RLNDz-10/630 (on request).

On request, KTP can be provided with street lighting lines that are automatically switched on by a built-in relay signal.

Example of ordering KTP with a capacity of 630 kVA, network voltage 6 kV, air inlet HV and cable inlet PN

KTPU-1K-630/6/0.4 U1 TU U 3.2-14152239-001:2004.

When ordering, it is also necessary to specify the customer's payment and shipping details.

Main technical parameters of KTP

At the customer's request, it is possible to replace circuit breakers on outgoing lines.
