Where are Heatsense heat resistant cables used?

Steel and Aluminium Industry
Glass Factories
Oil Refineries
Offshore Rigs
Pottery Kilns
Catering & Food Production Ovens

This range of cables also resist chemicals, acids, lubricants, and water and can be used as a power, coaxial, thermocouple and control cable. These cables can also be customer specified to operate in high radiation environments.

Advantages of our heat resistant cables?

Our Heat Resistant cable products are constructed with combinations of Mica Tape, Glass fibre or Ceramic fibre Insulations, for temperature ratings from -75°C to 1250°C.

As well as being easy to handle, easy to install and crimp, our cables have been proven to last up to four times longer than other high temperature cables. Installing Heatsense cables in equipment at the manufacturing stage means fewer breakdowns thus avoiding costly down time
