Data Sheet

Description

Power-limiting cables are formed by a coiled resistor alloy heating element wrapped around two parallel conductors. At a fixed distance the insulation is removed from one of the conductors and the process is repeated, removing the insulation from the other conductor. The distance between contact points forms the heating zone length.

Benefits

• Large variety of resistances

PI heating cables are available in a very wide resistance range to meet the requirements of the broadest range of applications.

• Easy termination on-site

They can easily be terminated in the field. The fabrication method keeps the cables very flexible and allows for easy stripping while printed metre marks facilitate on-site handling.

• Maximum chemical reistance of PTFE

The use of PTFE provides maximum chemical resistance and ensures the highest lifetime insulation resistance over the entire temperature.

Applications

PI heating systems can be used for applications involving maintain temperatures up to 200°C and exposure temperatures up to 300°C. Maximised circuit lengths can significantly reduce the total installated cost.
