Kiosk Substation (Unit Substation)

>>Enjoy the ease of using switchgear kiosks substation

Every kiosk substation (Unit Substation) project we complete is a little bit different, but one thing remains the same—these switchrooms are easy to use. Our solution is usually complete after final commissioning and installation, but the experience of the end user is never far from our minds.

Renewable energy plants love having Dowei Electric kiosk substation installed, because all the switchgear, control and protection equipment is contained in a compact, robust steel structure that promotes safety and reliability.   

Our kiosk substation are dynamic, problem-solving, space-saving electrical enclosures that get installed at battery energy storage systems (BESS), solar energy plants and wind farms. Inside each kiosk is an array of 40.5kV (medium voltage) secondary switchgear, which is available with or Free SF6 gas.

These ring main units efficiently convert power generated from renewable energy sources and transmit it to a primary collection substation, ensuring seamless integration into the electricity grid.

>>Product Overview
-Our kiosk substation (Unit Substation) are fully integrated steel switchgear enclosures with high durability.
-We offer fast kiosk production measured in weeks, not months.
-Medium voltage gas insulated switchgear (GIS) up to 40.5kV can be installed in these Dowei Electric purpose-built enclosures.
-Dowei Electric’s standard kiosk designs comply with the best international building codes; and our local subsidiaries ensure compliance with specific regional codes.
