Standard cable tray widths typically range from: Tray heights generally range from 25mm to 150mm, depending on cable volume and ventilation requirements. Thickness varies by material and load capacity: Galvanized cable tray thickness must meet ASTM A653 standards for corrosion. Our cable tray design considerations guide details key factors to consider when designing cable tray systems for industrial and commercial applications. Eaton's submittal builder tool. Cable tray systems are an alternative to wire ways & electrical conduit, which entirely protect wires. Many different types of wire can be accommodated in cable trays, including High-voltage power lines. Cable trays are components of the systems that support the cables and wires that supply. In practice, cable tray dimensions are a system of interrelated measurements —width, depth, length, and material thickness—that directly affect cable fill compliance, heat dissipation, structural loading, and long-term expandability. All illustrations, descriptions and technical information included in this document are provided as indications and can cable trays are equivalent. The Ladder Tray features light, rugged, tubular steel construction.
