PTFE INSULATED POWER CABLES
PTFE Cables have outstanding mechanical & electrical properties. They are heat resistant and have its application for temperature range from -65 Â°C to 260 Â°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.
