A tray cable is a cable approved for installation in a cable tray or raceway. In order to be approved for this, they must pass stringent tests and be extra durable. High-temperature tray cables are held at even higher standards. They can handle temperatures ranging up to 200° Celsius. TGGT wires— high-temperature wires made PTFE insulation and a fiberglass jacket— are usually applicable to the internal wiring of domestic ovens, cooking, and drying equipment.

Other high-temperature wires, known as thermocouple wire, can also be used in aircraft and petroleum processing. This type of high-temperature wire is used in the construction of a thermocouple temperature sensor. It is often flexible and determines a component's temperature and relays that information to the thermocouple.

Our Custom High-Temperature Tray Cable Solution

One Allied Wire and Cable customer who specializes in wind and solar power, electric vehicle chargers, and energy monitoring approached us to help design a cable to be used at a natural gas plant. This customer needed a Type E thermocouple wire rated for 200 degrees Celsius, which is not uncommon. However, they need it to be 18 AWG, and thermocouple wires mainly come in either 16 AWG or 20 AWG.

Taking the customer's needs into consideration, a member of our dedicated sales team helped design a 4-pair, 18 AWG, high-temperature thermocouple wire power limited tray cable (PLTC), rated to 300 volts. The custom tray cable was type CL2P and made to be oil, gas, sunlight, abrasion, and acid-resistant because of its environment.
