Does Saudi Arabia use cable trays

Yes, Saudi Arabia extensively uses cable trays for electrical installations, following both local and international standards.Overview of Cable Tray UseCable trays are widely implemented in Saudi Arabia for power, control, and signal cable management in substations, industrial facilities, and commercial buildings. The Saudi Electricity Company (SEC) standards, along with IEC and SASO regulations, guide the design, material selection, and installation of cable trays . They are essential for managing high-voltage (HV), medium-voltage (MV), and low-voltage (LV) cables, especially in the country's hot and dusty climate .Common Types of Cable TraysLadder Type: Most commonly used for MV and HV power cables due to superior ventilation, which is critical in high-temperature regions like Riyadh and Jeddah .Perforated Tray: Used for LV and control cables, offering moderate ventilation and support .Solid Bottom Tray: Provides protection against dust and sand, suitable for desert or industrial zones .Materials and DurabilitySaudi installations often use hot-dip galvanized steel (HDG) for corrosion resistance, stainless steel in coastal areas, and aluminum for lightweight applications . FRP (fiber-reinforced plastic) trays are also available for highly corrosive environments . Material selection considers heat, dust, humidity, and potential exposure to seawater.Installation PracticesFill Capacity: Typically 40–60% to allow heat dissipation and future expansion .Support Spacing: Horizontal spans up to 1.5–3 m depending on cable weight; vertical runs up to 2.4 m .Cable Segregation: Power and control cables are separated to prevent electromagnetic interference (EMI), .Grounding and Bonding: Metallic trays must be properly grounded and bonded continuously to avoid signal disturbances .Accessories: Include covers, dropouts, clamps, and expansion joints to ensure complete and safe cable management .Compliance and StandardsCable trays in Saudi Arabia comply with SEC Clause 5.14, SASO IEC 61537, and sometimes NEMA VE-1/VE-2 standards . These standards ensure proper load distribution, grounding, and durability under extreme operational conditions.Suppliers and AvailabilityCompanies like Adhwa and Matkel provide a wide range of cable tray systems in Saudi Arabia, including ladder, perforated, and wire mesh configurations, with options for hot-dip galvanized, stainless steel, aluminum, and FRP materials . They support both light-duty data routing and heavy-duty power distribution applications. In summary, cable trays are a standard and critical component of electrical infrastructure in Saudi Arabia, designed to withstand harsh environmental conditions while complying with local and international standards .
