High Temperature Cables

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

Steel Cables for blast furnace, electric arc furnace, hot & cold rolling
mills, steel refining faciliaties etc.
Communication High frequency cp-axial cables for VHF, UHF and XHF transmission
Marine Engine proximity wiring for good resistance to high temperatures,
fuel oils, chemicals, saline air / water etc.
Petrochemical Instrumentation & control, temperature sensing, fire warning etc.
Power In proximity to the turbines,boilers, ash handling etc.
