Installation of Explosion-proof Steel Plate Distribution Boxes in Iran

Explosion-proof steel plate distribution boxes in Iran must be installed following strict safety standards, proper alignment, and certified procedures to ensure reliable operation in hazardous environments.

Overview

Explosion-proof distribution boxes are critical for controlling and protecting electrical systems in hazardous areas, such as oil, gas, petrochemical, and industrial plants. In Iran, companies like GITCO and Darian Electric & Utilities Company manufacture and supply these enclosures in stainless steel or aluminum, certified according to ATEX and IECEx standards for zones 0 and 1, with ambient temperature ranges from -30°C to +65°C . These boxes can handle high voltage up to 11 kV and are suitable for both indoor and outdoor installations.

Installation Process

1. Site Preparation

• Ensure the control room or installation area is clean, safe, and fully prepared, with all interior work completed .
• Verify that the foundation is level and capable of supporting the weight of the distribution boxes.

2. Equipment Inspection

• Upon delivery, inspect the boxes for deformations, paint loss, completeness of instruments, accessories, and manuals. Record any discrepancies .
• Check that all grounding connections and fasteners are intact.

3. Positioning and Alignment

• Place the boxes on the foundation steel according to the layout plan.
• Align the ends and use a line at two-thirds height from the bottom for precise alignment.
• Adjust with 0.5mm shims, with a maximum of three shims per spot.
• Ensure top level differences between neighboring boxes do not exceed 2mm, and total unevenness is within 5mm .

4. Securing the Boxes

• Fix the boxes using bolts and galvanized screws, and weld high and low voltage switchboxes to reserved angle steels.
• Cover cable layers with checkered steel plates and insulate with 1200mm x 10mm insulation sheets on both front and rear sides .

5. Wiring and Connections

• Open the terminal chamber cover and connect cables through the cable glands, ensuring proper connection of internal and external ground wires.
• Close the cover, secure with fasteners, and tighten nuts to seal the cable .
• Never open the cover while the power is on, especially in hazardous areas.

6. Testing and Commissioning

• Conduct pre-operation inspections, trial operation, and handover tests to ensure proper functionality .
• Regularly inspect for damage, corrosion, or misalignment, and apply anti-rust oil on joint surfaces after maintenance .

7. Outdoor Considerations

• If installed outdoors, fit a rain cover to prevent water ingress and rust.
• Install in areas with low collision risk, away from heat sources, and in corrosion-resistant locations to extend service life .
