Installation of cable tray shafts in Iraq

Cable tray shafts in Iraq should be installed following approved shop drawings, using proper supports, spacing, and materials to ensure safe, durable, and accessible cable management.Planning and PreparationBefore installation, review the approved shop drawings to determine the layout, length, and location of cable trays and ladders in the building or facility . Ensure that the installation area is cleared, clean, and ready for MEP works. Materials, including cable trays, ladders, fittings, and accessories, should be inspected for compliance with project specifications and stored horizontally on flat surfaces with timber supports to prevent damage .Material and Equipment RequirementsCable trays in Iraq are typically made from hot-dip galvanized carbon steel to resist corrosion and meet project requirements . They can be perforated or ladder type, designed to carry loads up to 100 kg/m. Covers should be provided in areas with high risk of mechanical damage. Tools and equipment must comply with contract requirements and be in proper working condition .Installation ProcedureMarking Routes: Mark horizontal and vertical runs according to the shop drawings, ensuring no clashes with other services and maintaining sufficient clearance for cable pulling and future maintenance .Support and Fixing: Install cable tray supports using standard steel shapes, welded steel structures, or concrete anchors. Maximum support spacing is 3 meters for ladder trays and 2 meters for perforated trays .Tray Placement: Install trays flat whenever possible. Vertical or edgewise installation is allowed only in special cases, with cables secured using stainless steel strips .Connection and Bonding: Connect tray sections and fittings using bolted mechanical connectors or bonding jumpers to ensure electrical continuity .Cable Loading: Arrange cables in trays according to voltage and type, leaving 20% extra space for future expansion. Separate trays for HV/MV, LV power, control, and telecommunication cables are recommended .Testing and InspectionAfter installation, verify that all materials match the Issued For Construction (IFC) drawings and project specifications. Inspect supports, alignment, and bonding connections. Any discrepancies or damaged materials should be reported and corrected before cable installation .Local Suppliers in IraqSeveral suppliers provide cable tray systems suitable for industrial and construction projects in Iraq, including Kanza Iraq, ED-Iraq, and Basra Logistics, offering technical support, custom solutions, and competitive pricing .By following these steps and adhering to project specifications, cable tray shafts can be installed safely, efficiently, and in compliance with international and local standards.
