PTFE Insulated Cables have wide applications in petroleum, chemical processing, metallurgy and power generation fields. These cables can endure up to 1000 degree C temperature. Conductor of such PTFE products is made of copper-nickel or copper or iron or nickel-silicon. These are mainly used for temperature controlling and measurement jobs. Advanced vacuum melting and wellbore annealing technology has been followed to develop such cables. Quality of these products has been verified on the basis of tests conducted by alloy analyzer, hardometer etc.
