High temperature cables are used in areas where both working temperatures and ambient temperatures are too high. They are made with a wide range of conductors, insulating materials and screening materials depending on the temperatures and conditions under which the cable has to perform.
Single core high temperature hook-up wires & Multi core / Multi pair, Screened & Unscreened and Armoured & Unarmoured cables:
| Insulation Material | Temperature Range | Characteristics |
| Special High Temperature Yarn | -72 to 1000° C | Heat and high temperature resistance. |
| PTFE | -200° C to 260° C | Excellent chemical resistance. High temperature stability. |
| FEP | -200° C to 200° C | Good chemical resistance. Thin wall insulation due to good electrical properties. |
| PFA | -200° C to 250° C | Good chemical resistance, Thin wall insulation due to good electrical properties. Good flexibility. |
| ETFE | -150° C to 150° C | Mechanically tough. |
| XL ETFE | -150° C to 250° C | Good electric insulation, radiation resistance, ARC tracking and cold flow. |
| PEEK | -160° C to 250° C | Mechanically very tough. High temperature and radiation resistance |
| Kapton Tape | -250° C to 300° C | Very thin wall insulation. High temperature resistance. |
| Silicon Rubber | -40° C to 180° C | Flexible and abrasion resistance |
| Ceramic Yarn / Quartz Yarn Braiding | 600° C | Bad conductivity & heat and high temperature resistance. |
| Screening | Individual and / or overall with following options – – Aluminum Mylar / Copper Tape with Tinned Copper Drain Wire or – Braided with Bare or Tinned or Nickel Plated or Silver Plated Copper |
| Armouring | Steel Galvanised wire, stainless steel wire, high strength steel wire braiding |
| Standards | JSS 51034, JSS 51038, UL 1581 |
Industry & Applications
