kioks

Kiosk-type substations are self-contained metallic construction, environmentally controlled, and comprise practically MV switchgear, Transformers, and LV panels or different variations as per the customer’s demand.

 

Kiosk substations can be manufactured in various configurations to suit the available space and are suitable for use in industrial, commercial, and resident complexes sites.        Kiosk consists of (3) main compartments:

 

     ♦ Medium Voltage compartment.

     ♦ Transformer compartment.

     ♦ Low Voltage compartment.

 

Each compartment is equipped with all the necessary equipment according to the customer specifications. The M.V and L.V compartments are arranged at both ends of the transformer compartments.

 

     ♦ The kiosk substation is fully assembled at our factory as one unit to be delivered to the site.

     ♦ Galvanised sheet steel, Aluzinc, or Al Sheets used for mainframe upon customer demand.

     ♦ Main base produced from NPU or 4mm Steel according to the project specifications.

     ♦ Epoxy dust powder paint used for the cover.

     ♦ The kiosk is manufactured according to EN 62271-­202.

     ♦ Walls and roofs are double-layer with using eps or rock walls.
