The Integral Transformer Substation (ITS) is intended for reception, transformation and distribution of electrical energy of three-phase alternating current with a frequency of 50 Hz in systems with a glukhozazemlenny transformer neutral on the party of the lowest tension in rural power networks.
KTP are issued on tension of 6 and 10 kV, 25... 400 kVA.
The cabinet of RUNN is completed according to the scheme coordinated with the customer, the metering station of the electric power is mounted on the party of NN.
VN tension – air input, the disconnector in KTP is not established and is not included in the package of delivery.
NN tension – an air and cable conclusion.
Are a part of KTPP:
- the input device from the highest tension (UVN);
- power transformer;
- the distributing device from the lowest tension (RUNN).
KTPP are issued:
- one-transformer (KTPP) – right and left;
- two-transformer (2KTPP) – single-row and two-row.
In two-row substations for electrical and mechanical connection of sections the busline is installed. Distance between facades of opposite sections (depending on the order) – 1800, 2300, 2800 mm. The option of production of the busline of the non-standard sizes is possible.
