Professional High-Temperature Wire Harness Manufacturing
OurPCB manufactures high-temperature wire harnesses for applications requiring heat-resistant cables up to 450°C. Our wire harness solutions utilize specialized insulation materials including PTFE (Teflon), silicone, and fiberglass for reliable performance in extreme thermal environments.
For automotive applications, we manufacture engine harnesses that withstand underhood temperatures near exhaust systems and turbochargers. Our heat-resistant cables maintain flexibility and electrical performance through repeated thermal cycles.
Industrial applications including furnaces, ovens, and thermal processing equipment require cables that resist heat degradation. We offer fiberglass-insulated harnesses for the highest temperature requirements and silicone for applications needing flexibility.
Our engineering team helps select appropriate materials based on continuous operating temperature, peak exposure, chemical environment, and mechanical requirements. From prototypes to production, we deliver high-temperature solutions that last.
High-Temperature Harness FAQ
We offer wire and cable assemblies with continuous temperature ratings from 150°C (silicone) up to 450°C (fiberglass). The appropriate material depends on your specific temperature requirements, flexibility needs, and environmental conditions.
For automotive engine compartment applications, we typically recommend PTFE or silicone insulation. PTFE offers excellent chemical resistance to oils and fuels, while silicone provides better flexibility. Both handle typical underhood temperatures of 150-200°C.
Silicone and some PTFE constructions maintain flexibility for moving applications. Fiberglass is more rigid and best suited for fixed installations. We can recommend appropriate constructions for your flex requirements.
Yes, we work with high-temperature connector families from manufacturers like Amphenol, TE Connectivity, and Deutsch that are rated for elevated temperatures. Connector selection is matched to your temperature and environmental requirements.
