Heat resistant cables are required wherever electrical or signal cabling must operate reliably in environments exposed to extreme heat. Heatsense Cables manufactures specialist cables for industries including aerospace, oil and gas, steel, automotive, aluminium and nuclear. Depending on their construction, cables can also provide resistance to chemicals, acids, lubricants and water and can be designed for power, coaxial, thermocouple and control applications. Bespoke cables can also be specified for high-radiation environments and temperatures up to +1250°C (+2282°F).

Q: What are the advantages of heat resistant cables?

Heatsense heat-resistant products can be constructed using combinations of mica tape, glass fibre and ceramic fibre insulation for temperature ratings up to +1250°C (+2282°F). They are designed to be practical to handle, install and terminate while providing reliable performance in extreme environments. Heatsense cables have been proven in demanding applications where increased cable life can reduce failures, maintenance requirements and costly equipment downtime.

Q: What are the key features of Heatsense heat resistant cables?

Heatsense heat-resistant cables can be supplied in multicore configurations and multiple colours, with conductor sizes ranging from 0.50mm² to 35mm² and a variety of cable lengths. Cable construction, conductor materials, insulation, screening and protective layers can also be selected according to the requirements of the application.

Heatsense manufactures a range of heat tolerant cables which can withstand temperatures up to 1250°C (+2282°F). We also own the INTEMP™ cable brand. Whether you are looking for a solution to work in an environment with extremely high temperatures or for higher accuracy and strict tolerances, we offer a range of cables developed to include increased mechanical resistance, radiation resistance and shielding.

Key factors to consider include conductor materials, insulation, resistance to environmental conditions and compliance with safety standards.

Why choose Heatsense for Heat Resistant Cables?

Heat resistant cable performance is fundamentally driven by the interaction between conductor materials, insulation systems and protective layers, particularly in extreme environments where multiple stress factors occur simultaneously. At Heatsense, cable design begins with a deep understanding of how materials behave under thermal load, radiation exposure and mechanical stress. Advanced insulation systems such as mica tapes, glass fibre, ceramic and fluoropolymers are carefully selected to deliver stability across a wide operating range, from sub-zero conditions through to temperatures exceeding 1000°C.

These materials are not interchangeable; each offers distinct advantages in terms of dielectric strength, flexibility, chemical resistance and long-term durability. As explored in our Material Insights resources, fluoropolymers such as PTFE and PFA provide exceptional thermal stability and electrical performance, while inorganic systems such as mica and ceramic deliver superior performance in fire survival and ultra-high temperature applications.

Selecting the correct heat resistant materials is therefore not just a question of temperature rating, but of understanding the complete operating environment and the interaction between each cable layer. For example, fluoropolymers offer excellent processability and flexibility for complex cable constructions, whereas glass fibre and ceramic systems provide enhanced structural integrity at higher temperatures where polymers may degrade. Increasingly, engineers must also consider regulatory and environmental factors, particularly around PFAS materials, balancing performance requirements with evolving industry standards.

By combining material science expertise with advanced manufacturing processes such as extrusion, braiding and sintering, Heatsense develops bespoke heat resistant cables that maintain electrical integrity, mechanical strength and reliability over extended service life. This holistic approach ensures that each cable is optimised not just for temperature, but for the full range of environmental, electrical and mechanical challenges it will face in real-world applications.

Certified to AS9100, ISO 9001, and ISO 14001 standards, our commitment to quality ensures that every cable meets the highest industry standards. Whether you require high-temperature sensor cables, thermocouple extensions, or extreme heat power transmission cables, Heatsense Cables provides tailored solutions that push the boundaries of thermal resilience, performance, and innovation.
