Metal Kiosk

Kiosk type substations are self-contained metallic construction, environmentally controlled and comprise practically MV switchgears, 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 suctomer specifications. The M.V and L.V compartments are arranged at both ends of the transformer compartments.


     ♦ 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 main frame upon customer demand.

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

     ♦ Epoxy dust powder paint used for cover.

     ♦ Kiosk is manufactured according to EN 62271-­202.

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

Electrical Connections

LSK type sheet steel kiosk has AC and emergency internal lighting system as attached technical drawings.

 

LSK type sheet steel kiosks are generally electrical assembled according to the table, depending on the transformer’s power. In special cases, changes are made according to the system needs.
