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:

Construction - Single Core or Multi Core / Pairs
Voltage Grade - 250VAC, 600VAC & 1000VAC (Rating as per MIL 16878, VDE, DIN, ANSI)
Conductors - Annealed bare and/or tinned copper conductor (up to 120° C)
Annealed silver plated copper conductor (up to 200° C)
Nickel plated conductors (up to 260° C)
Insulation
Insulation Material Temperature Range Characteristics
Varnished Fibre
Glass Braid
-72° C to 350° C High Temperature Resistance
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
PTFE -200° C to 260° C Excellent chemical resistance , High temperature stability
Kapton tape -250° C to 300° C Very thin wall insulation, High temperature resistance
PEEK -160° C to 250° C Mechanically very tough
High temperature and radiation resistance
ETFE -150° C to 150° C Mechanically tough
Silicone Rubber -40° C to 180° C Flexible & abrasion 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.
