Complete transformer substations dead-end - KTP-1 with a capacity of 25 - 630 kVA, HV voltage 6 or 10 kV and LV voltage 0.4 kV are intended for receiving, converting and three-phase electrical power distribution alternating current with a frequency of 50 Hz in systems with solid-grounded neutral of the transformer on low voltage side. KTP-1 are intended for power supply of agricultural, industrial consumers, individual communities points and small industrial facilities in areas with a temperate climate (from -45 ° С to + 40 ° С). KTP-1 is installed on the simplest concrete site. Type of climatic modification U1 in accordance with 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, corrosive gases and vapors in concentrations that reduce the parameters of the KTP within unacceptable limits; 3. Wind speed up to 36 m / s (wind pressure up to 800 Pa); 4. Type of atmosphere - II in accordance with GOST 15150. High-voltage input - air or cable, outgoing line branches - air or cable. Dead-end KTP-1 are manufactured as one-transformer and two-transformer (with high and low voltage sectioning). Circuit breakers are installed on the LV side. Their number and rated current are shown in the table. The package of delivery of the KTP includes UVN (air inlet) and LVDN cabinets, a power transformer, an outdoor disconnector RLNDz-10/630 (on request). On request, the KTP can provide street lighting lines, which are switched on automatically by a signal from the built-in relay.
