Guide to Wire and Cable Insulation and Coverings

Which insulation Material? usable temperature range Application Note
PVC -10°C to 105°C Good general-purpose insulation for “light” environments. Waterproof and very flexible.
-75°C to 250°C Resistant to oils, acids other adverse agents and fluids. Good mechanical strength and flexibility. PTFE better for steam/elevated pressure environments
(taped & wrapped)
-75°C to 250/300°C Resistant to oils, acids other adverse agents and fluids. Good mechanical strength and flexibility.
Glassfibre (varnished) -60°C to 350/400°C Good temperature range but will not prevent ingress of fluids. Fairly flexible but does not provide good mechanical protection.
High temperature glass fibre -60°C to 700°C Will withstand temperature up to 700°C but will not prevent ingress of fluids. Fairly flexible, not good protection against physical disturbance.
Ceramic Fibre 0 to 1000°C Will withstand high temperature, up to 1000°C. Will not protect against fluids or physical disturbance.
stainless steel
-60°C to 350/400°C Good resistance to physical disturbance and high temperature (up to 400°C). Will not prevent ingress of fluids.

Technical Resources

We offer comprehensive reference guides for users of thermocouples, PRTs and thermistors and associated instrumentation.

Detailed enough for engineers and scientists, it is also suitable for technicians and students. Written with practical bias, the guides contain considerable reference data and basic theory and is therefore of great value as a training aid for those entering the field of temperature measurement and control.

The broad scope of the guides includes detailed temperature sensor guidance, sensor theory and practice and comprehensive applications guidance. The guides describe temperature control, transmitters, instrumentation and data acquisition and a reference section carries that has a wealth of data on thermocouple and platinum resistance thermometry.

The emphasis is on practical aspects, but the basic theory and applications aspects will be of particular interest to students and apprentices.
