Complete transformer substation KTP-SESH-B(M) for Yuganskneftegaz

General Description

Classical outdoor switchgear KTP-SESH-B(M) 35/6 kV is used by oil-producing companies. It is intended for electric supply to well pads. This solution combines a 35 kV outdoor switchgear and KRU-SESH-63 cubicles in a modular building without substation control station. The substation control equipment is located in the module with KRU-SESH-63 cubicles. Domestic equipment is used and installed.

Easy "reading" of the substation scheme by the service personnel. 35 kV equipment is installed in the form of outdoor switchgear.
.Possibility to supply auxiliary needs under any conditions. Transformers of auxiliary needs TSN-SESH 35/0.4 kV are installed to the switches.
Possibility to control the substation using remote control.
Work in a wide temperature range from -60° to + 40°C.
