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 –
