Technical Data of PTFE (Teflon) cable
PTFE cables have outstanding Mechanical & electrical properties. These are heat resistant. Its properties qualify them for an ever-widening range of wiring a applications, they are used in many situations, where temperature is between -65°C and +250°C.

In most adverse uses, where chemical fumes and liquids would render all other cables cables useless, PTFE is the most well-known and durable polymer and has been used in the cable industry for many years, It’s outstanding dielectric properties, even at elevated temperatures, make it most suitable for insulation of cables.

Construction:-
These cables consist of :-

1. A solid or stranded conductor of either
   - Silver plated copper clad steel (SCCS) or
   - Anealed bare Copper.
2. A dielectric layer or wrapped and sintered PTFE tape.
3. one or two braids of silver plated copper wire [In case of Shielded cables]
4. An overaii jacket of:
   1. Wrapped and sintered PTFE tape.
   2. One or two wraps of PTFE tape, one or more glass fiber braids and coated with a special high temperature varnish.

• High dielectric values of any known flexible insulator resulting in excellent space and weight saving.
• Wide operating temperature range-65°C to + 250°C.
• Inert to most chemicals and fluids even at elevated temperature and pressure.
• Unaffected by oils, lubricants, hydraulic fluids and aircraft / rocket fuel.
• Insulation by tape wrapping and sintering process-ensures uniform insulation thickness eith near extruded finish.
• Non –flammable, non – toxic, resistant to solder iron damage.
• Suitable for high frequency operation.
• Immune to algai, fungus and water absorption.
• Resistance to UV radiation and stress creaking.
• High strain and abrasion resistance.

Technical Specification:
The PTFE equipment wires are as per US military MIL- W – 16878D and Indian defence specifications JSS 51034.92. As per these standards, equipments wires are classified in three main working voltage grades. i.e.
250 v AC rms (ET) grade
600 V AC rms (E) grade
1000 V AC rms (EE) grade

The Main Technical Features are as follows:
Fine wire strands. Made from silver plated electrolytic grade copper wire, stranded to from perfectly round conductor. Teflon (PTFE) concentricity of inner conductor, available in bright eleven solid colors & combination of colors as bi colors.

Insulation radial thickness.
ET-   250 V ACrms Grade 0.15 mm Nominal
E -    600 V ACrms Grade 0.25 mm Nominal
EE -  1000V ACrms Grade 0.40 mm Nominal.
