Tips to Choose the Right Temperature Teflon as per Your Usage

PTFE Multi-core cables for Instrumentation and control applications are manufactured as per MIL-DTL-27500H / JSS 51038 specification to meet specific customer requirements.
The primary wires are PTFE insulated meeting requirements of JSS 51034/ MIL-W-16878/BS3G210/NEMA HP3. The cable possesses all the unique electrical and mechanical properties of PTFE and is available in size from single wire screened or/and jacketed up to cable with a maximum of 66 pairs twisted and/or screened and/or jacked as per required.

Applications Of PTFE Insulated Wires & Cables

  • Electronic Test Equipment
  • Communication Equipment (mobile and manpack wireless sets)
  • Equipment for Aircraft, Radar, Navigation, Electro-mechanical applications, Satellites, Research Equipment for Aerospace, Navy & Meteorology
  • Control Equipment for Atomic Energy, Satellite Launching, Ground Control, Reactors and Process Control, Telephone Exchange, Lifts
  • Computers, Flight simulators
    High-performance motors, transformers, and rectifiers
  • Infra-red sensing equipment
  • Thermo-couple and compensating cables
  • Air-field lighting equipment
  • High-temperature lighting fittings (sodium lamps etc.)
  • Refrigeration equipment
  • Load cells and pressure transducers
  • Electro-medical/Neuro-surgical equipment
  • High-temperature control valves
  • Furnace and oven wiring

PTFE Insulated Special Equipment Wires

Please refer to the table for commonly available sizes. Within the normal range, a larger number of strands are available to improve flexibility and flex-life; 19 strands up to AWG 30, 37 strands up to AWG 20, and 60 strands for AWG 9, 10, 11, 12, and 13. In the two larger sizes AWG 6 and 8, compact 61 strands true concentric constructions (compared to Rope lay 19 x 7) are about 15% lower in OD, weight, and cost, although slightly stiffer.

We offer finer sizes, having thin-wall PTFE insulation, highly flexible (with flex-life) constructions using Silver Plated High Strength Copper Alloy (SPHSCA). Sizes as small as AWG 37/7/45 (0.43 mm). Even such fine sizes are 100% tested.

For Wire-Wrap wire, advantages of PTFE insulation are now available in single strand size up to AWG 36 (OD 0.43 mm), and multi-strand 3607 or 3707 with OD 0.38 mm

ETFE (Medium weight and Lightweight)

Single or Multi-strand Conductor Insulation 600V available in medium weight and lightweight.
EXOTHERM designs and manufactures a wide variety of standard and custom ETFE Insulated Hook-up/Equipment Wires. These wires are available in normal-weight and a thin-walled lightweight versions specially used in aviation and aerospace industries, all the standard wires manufactured as per the popular military standards.
