General Description

Transformers TM-SESH, TM(N)-SESH capacity of 1 000-6 300 kVA. ТМ(N) SESH - with voltage adjustment under the load RPN. TM-SESH - with switching branches without excitation windings of a PBV. Cooling system type "M".
Transformers TM-SESH, TM(N)-SESH 35 kV are designed for operation in electrical networks of complete transformer substations. Working conditions - in the open air.

Is possible to install a thermometer that has the ability to enter up to 4 temperature values and has signal feed contacts for ASUTP.
Used the switching device RPN, provide a high guaranteed reliability.
Installation of a pressure relief valve having contacts for feeding a signal to the ASUTP.
