What type of cable is used in cable trays

The most commonly used cables in cable trays are Tray Cables (TC), Instrumentation Tray Cables (ITC), and Power-Limited Tray Cables (PLTC), each designed for specific power, control, or signal applications.Common Cable Types

1. TC (Tray Cable) TC cables are multi-conductor cables designed for power, lighting, and control circuits in industrial and commercial environments. They feature enhanced insulation and jacketing to withstand mechanical stress, moisture, oil, sunlight, and chemicals. TC cables are rated for 600 volts and can be installed in cable trays, raceways, or outdoor locations supported by a messenger wire. TC-ER (Exposed Run) variants allow short exposed runs up to six feet between trays and equipment without continuous support, meeting crush and impact standards . 2. ITC (Instrumentation Tray Cable) ITC cables are used for low-energy control, signal, and communication circuits, typically not exceeding 150 volts and 5 amps. They are available in shielded or unshielded constructions, often with twisted pairs and optional metal armor. ITC cables are ideal for PLCs, DCS systems, transmitters, and other instrumentation applications. Some ITC-ER versions permit short exposed runs similar to TC-ER . 3. PLTC (Power-Limited Tray Cable) PLTC cables are designed for Class 2 and Class 3 power-limited circuits, commonly used in alarm systems, intercoms, security, and building automation. They provide safe, code-compliant routing of low-voltage power and control signals within cable trays .

Key Considerations
  • Compliance: All tray cables must meet NEC requirements (NEC Articles 336, 725) and UL standards.
  • Mechanical Protection: Cables in trays are supported continuously and secured at intervals, with TC-ER and ITC-ER allowing limited exposed runs.
  • Environmental Resistance: Tray cables are designed to resist heat, moisture, chemicals, and physical damage, making them suitable for industrial and commercial installations . In summary, TC, ITC, and PLTC cables are the primary types used in cable trays, selected based on voltage, application, and environmental conditions to ensure safety, durability, and compliance with electrical codes.
