They are available in flat & twisted pair construction. They can be further shielded or outside SS Metal braided as per requirement.

PTFE INSULATED INSTRUMENTATION CABLE

ELTEC PTFE Instrumentation Cable products are used for signal and energy transmission with minimum interference, and the they are sunlight, heat, and moisture resistant means they can survive in some of the toughest conditions.

PTFE INSULATED POWER CABLES:

ELTEC PTFE Insulated Power Cables are used where there is surrounding high temperature near boilers in processing plants and used for wirings in ovens, furnaces, heaters. PTFE wires normally come with silver plated copper wire conductors (190°C) or nickel plated copper wire conductors (260°C on request).

PTFE INSULATED RTD CABLE

ELTEC PTFE Insulated RTD CABLES are generally used to transmit signal from RTD sensor to control unit.
Multi stranded SPC conductors are used and are available in 2 core 3 core, 4 core, 6 core, 8 core or even more as per requirement. They are further SPC shielded or outside SS Metal braided as per requirement.

PTFE INSULATED WIRES & CABLES

PTFE Cables have outstanding mechanical & electrical properties. They are heat resistant and have its application for temperature range from -65 °C to 260 °C.
In most adverse industrial conditions, where chemical fumes & other liquids make all other types of cables are vulnerable, PTFE polymer becomes an excellent solution as it is chemically inert to most of industrial chemicals. Its outstanding di electric properties even at high elevated temperatures make it suitable for harsh industrial applications.
The PTFE equipment wire are as per US Military MIL – W – 16878D and Indian defense specifications JSS 51034.92. As per these standards, PTFE wires are classified in three main working voltage grades.
