ARSK Series Sheet Metal Kiosks are transformer and distribution centers manufactured from galvanized and electrostatic powder coated sheet metal in desired dimensions for all application areas. Armtek Electric sheet metal kiosks (transformer substation), which can be used in all climatic conditions, meet the medium voltage – low voltage (MV/LV) distribution center needs of electricity distribution companies and special projects.
Technical Specifications
The bases are NPU or NPI shaped according to the load on the ground and the NPU and NPI shapes are covered with hot dip galvanization.
Frame
If the customer does not want a different thickness in the frame part of the sheet metal kiosk, it is manufactured from 2mm galvanized sheet.
Doors
The doors can be opened 120° outwards and the rate of the impact protection is IK20.
Application Areas
- Iron casting workshops
- Oil pipelines
- Industry
- Shipyards
- Emergency and backup power facilities
- Mining operations
Compartments
MV Compartment
Metal Enclosed Modular Switchgears, Metal Clad cells and RMU type cells can be used in the MV compartment. MV compartment dimensions are determined according to the equipment dimensions in the compartment.
Transformer Compartment
Dry type transformer and oil type transformer can be used in the transformer compartment. Transformer compartment dimensions are specified according to transformers power.
Technical Specifications
LV Panel Compartment
In the low voltage (LV) room, MCC Distribution Board, AC Distribution Board, DC Distribution Board, HVAC Board, Fire Control Panel, UPS, Scada – RTU Panel and other LV panel can be installed.
Battery-Rectifier Room
The battery room has Ni-Cd batteries and DC cutters. If desired, the battery room can be designed according to Zone 2 Hazardous Area Classification. (optional)
Interior Lighting, Outdoor Lighting
All rooms in the Compact Substation are equipped with a lighting system that meets the standards. When preferred, Atex certified indoor and outdoor lighting equipment and sockets can be selected for Zone 2 Hazardous Area Classification. Emergency exit luminaires can be placed on the doorways. And these luminaires include an emergency lighting unit.
Grounding
Electrical appliances are connected to an isolated grounding busbar. Separate grounding system is used for doors, base, walls and roof to prevent electric shock in case of touch.
Flooring
The floor covering is made of fireproof rubber. It has A1 rating and 50kV insulation level. (This feature is optional)
Fire Detection and Fire Extinguishing
All rooms can be equipped with fire and smoke detectors. In case of emergencies in hazardous situations, the HVAC system is deactivated and warning lights and alarm are activated. (This feature is optional)
Air Conditioning System
In the Compact Substation, HVAC can be used to maintain constant internal temperature and humidity. Stabilization in all rooms is provided by air ducts. (optional)
Advantages of the System
- Since it is a lighter product compared to concrete kiosks, it provides convenience in transportation and installation.
- Since it is designed in accordance with the elements to be used inside, it can be manufactured in a wide range of sizes.
- Especially in substations with RMU, they are preferred because they provide great advantages in terms of size and weight.
- Large centers can be established thanks to their modular structures and prefabricated features.
- In disassembled shipments to abroad, it provides great savings in terms of transportation.
- High operational safety.
- Manufacturing solutions suitable for special projects.
- Easy transport and easy operating.
