KIOSK (Outdoor Compact Substation Enclosure)

High voltage / low voltage (HV/LV) outdoor prefabricated (kiosk) substations have been largely used for more than thirty years, initially in Europe then gradually in other continents. Prefabricated substations are defined as an enclosure containing transformers, low voltage and high voltage switchgear, connections and auxiliary equipment to supply low voltage energy from a high voltage system or vice versa. In 1995 the first International Standard prescribing the operating conditions, characteristics, general requirements and testing methods applicable to prefabricated substations was published by the International Electrotechnical Commission (IEC) as IEC 61330. The first prefabricated substation in Australia to successfully pass a type test for personnel protection, was manufactured. This was followed by successful testing of a Ring Main Unit (RMU) outdoor enclosure in 2008. GEIS Electric continues to design prefabricated substations at the highest level of safety for the operator and the public.

Advantage of KIOSK

Kiosk substations contain electrical equipment, often located in a public environment, requiring them to meet the highest safety standards. An internal arc rated kiosk substation design is manufactured to withstand the extreme pressure and force generated during an internal electrical fault. The risk of equipment failure in a kiosk substation is minimized through the design. In the rare occasions of medium voltage equipment failure, an internal arc rated kiosk design minimizes the risk of injury to nearby public or an operator working with the kiosk door open. The design ensures that extremely hot gases generated during a fault are cooled via a patented filter, reducing the effects of overpressure and flame within the enclosure. The design limits the release of projectiles and flaming particles, which could potentially injure the public, operators or start bushfires.
