CABLE TRAY SELECTION

Per the National Electrical Code, a cable tray system is "a unit or assembly of units or sections and associated fittings forming a rigid structural system used to securely fasten or support cables and raceways."

  • Cable trays support cable the way that roadway bridges support traffic.
  • A bridge is a structure that provides safe passage for traffic across open spans.
  • Cable tray is the bridge that allows for safe transport of wires across open spans.
  • Therefore, think of cable tray as the structural component of a building's electrical system.


    Types of Cable Tray are available :
  • Ladder
  • Solid Bottom
  • Trough
  • Channel


    Ladder Cable Tray provides:
  • Solid side rail protection and system strength with smooth radius fittings and a wide selection of materials and finishes.
  • maximum strength for long span applications
  • standard widths of 100mm - 2000mm
  • standard depths of 1mm - 3mm
  • standard lengths of 40mm - 200mm


Applications :
Ladder cable tray is generally used in applications with intermediate to long support spans, 2.50mtr - 3.00mtr

    Solid Bottom Cable Tray provides:
  • Non ventilated continuous support for delicate cables with added cable protection available in metallic and fiberglass.
  • Solid bottom metallic with solid metal covers for nonplenum rated cable in environmental air areas
  • standard widths of 50mm - 2000mm
  • standard depths of 1mm - 3mm
  • standard lengths of 50mm - 200mm


Applications :
Solid Bottom cable tray is generally used for minimal heat generating electrical or telecommunication applications with short to intermediate support spans of 2.50mtr - 3.00mtr .

    Trough Cable Tray provides:
  • Moderate ventilation with added cable support frequency and with the bottom configuration providing cable support every 4 inches. Available in metal and nonmetallic materials.
  • standard widths of 300mm - 2000mm
  • standard depths of 1mm - 3mm
  • standard lengths of 70mm - 200mm


Applications :
Trough cable tray is generally used for moderate heat generating applications with short to intermediate support spans of 5.00mtr - 7.00mtr .

    Channel Cable Tray provides:
  • an economical support for cable drops and branch cable runs from the backbone cable tray system.
  • standard widths of 450mm - 2000mm
  • standard depths of 1mm - 3mm
  • standard length of 40mm - 200mm


Applications :
Channel cable tray is used for installations with limited numbers of tray cable when conduit is undesirable. Support frequency with short to medium support spans of 2.50mtr - 3.00mtr .
