Which cable tray company should I use for the intrinsically safe cable

For intrinsically safe (IS) cables, select a supplier that offers compliant, high-quality trays with proper separation, grounding, and environmental protection, such as Spina Group or other certified industrial tray manufacturers.Key Considerations for IS Cable Tray SelectionCompliance with Standards: Cable trays must meet NEC, NEMA, and UL standards for hazardous locations. IS cables can be installed in Class I, Divisions 1 and 2, and Class II, Divisions 1 and 2 locations, but the tray system must comply with article 504 for separation and grounding requirements . Material and Environmental Suitability: Choose trays made from stainless steel, galvanized steel, or aluminum depending on environmental conditions. Stainless steel is ideal for corrosive or wet areas, while aluminum offers lightweight strength. Protective covers can shield cables from dust, moisture, and mechanical impacts . Separation and Safety: IS and non-IS circuits can share the same tray if separated by at least 2 inches or by a grounded/insulating partition. Alternatively, metal-sheathed or metal-clad cables can be run together without separation if the sheathing can carry fault current to ground . Supplier Capabilities: Look for suppliers that provide custom sizes, CAD support, technical guidance, and after-sales assistance. Companies like Spina Group offer a wide range of ladder, perforated, closed-bottom, and wire-mesh trays, with full compliance to international standards and long-term support . Installation Support: Ensure the supplier can provide guidance on tray sizing, load capacity, support spans, and proper cable routing to maintain safety and prevent overloading . Long-Term Reliability: Consider suppliers with proven experience in industrial and hazardous environments, offering corrosion-resistant materials, thermal expansion joints, and grounding provisions to ensure durability and safety over time .Recommended Supplier ExampleSpina Group (Schiavetti Tekno): Offers stainless steel, galvanized, and wire-mesh trays suitable for IS cables, with custom sizes, protective covers, and full technical support. Their systems are designed for industrial plants, refineries, and infrastructure projects, ensuring compliance with NEC and international standards . By prioritizing compliance, material suitability, separation, and supplier expertise, you can safely install intrinsically safe cables in hazardous locations while ensuring long-term reliability and regulatory adherence.
