Trapezoidal Cable Tray Specification Table

Trapezoidal cable trays are available in a wide range of models with detailed specifications covering dimensions, materials, finishes, load ratings, and CAD resources for design integration.

Overview of Trapezoidal Cable Tray Models

Trapezoidal cable trays are designed for power and control cable management in industrial, commercial, and utility installations. They are typically made from steel, stainless steel, or aluminum, with finishes such as hot-dip galvanizing, powder coating, or epoxy coating for corrosion resistance . Models vary by:

• Width: Commonly 50 mm to 600 mm or more
• Height/Depth: Typically 50 mm to 150 mm
• Length: Standard straight sections range from 2 m to 3 m, with custom lengths available
• Load Capacity: Rated according to span and material, conforming to NEMA VE 1-2017, UL, and IEC standards

Key Specifications

• Material Types: Carbon steel, stainless steel, aluminum
• Surface Treatments: Hot-dip galvanized (ASTM A123), powder-coated, epoxy-coated
• Standards Compliance: UL Listed, CE marked, ISO 1461, ANSI/NFPA 70, NEMA VE 1-2017
• Accessories: Covers, bends, tees, reducers, couplers, and supports
• Environmental Suitability: Indoor, outdoor, corrosive environments, and high-temperature applications

Popular Models and Variants

1. Standard Trapezoidal Cable Tray: Open-top design, suitable for heavy-duty power cables
