Two-transformer walk-through substation of kiosk type. We made this package transformer substation for a customer from the city of Petrozavodsk. ⠀
The structure of the hull is made of two parts: the first part is the RUVN compartment, the second is the TMG and LVDU compartment. The structure is divided into two parts for easy transportation. The RUVN compartment is made in the form of built-in cameras KSO-393. ⠀
The switching devices were VNA type load break switches, RVZ type disconnectors and a vacuum circuit breaker manufactured by Elkom Group of Companies. ⠀
This was the first time we used this company's vacuum circuit breakers. They are assembled in St. Petersburg, and the Korean components are produced by Hyundai Electric.
The low side of the substation (LVSN) turned out to be compact, because it has bar switch switches manufactured by EFEN GmbH (Germany). The use of strip switches allows to significantly reduce the size of the substation due to the vertical arrangement of the fuse-links in the switch.
