High-Temperature Cable
High-Temperature Cable

The demand for high-temperature cables for power and signal transmission is steadily increasing in today’s industrial and technological landscape. These specialized cables operate in extreme temperatures, including wiring harnesses and cable assemblies. They ensure stable signal or power transmission, providing reliable connections for various industries’ control systems and electrical instruments. Leading manufacturers innovate continually to meet these demands with top materials and technologies.

Materials and Classifications

The heat resistance of high-temperature cables depends on the insulation materials. Common materials include:

  • PTFE (Polytetrafluoroethylene)
  • ETFE (Ethylene Tetrafluoroethylene Copolymer)
  • PVC (Polyvinyl Chloride)
  • CPE (Chlorinated Polyethylene)
  • SBR (Styrene-Butadiene Rubber)
  • EPR (Ethylene Propylene Rubber)
  • Silicone

These materials have different heat-resistant characteristics and application ranges. For example, PTFE and ETFE maintain stability at higher temperatures. Plastics like PVC and CPE have lower heat resistance and are suitable for general high-temperature environments. Rubber materials like SBR and EPR perform well at moderate temperatures. Meanwhile, silicone has excellent resistance to both high and low temperatures, making it ideal for extreme conditions. These cables often include cores made of copper or other conductive materials to ensure optimal electrical performance.

Application Areas

High-temperature cables are widely used in various industries, including:

  • Metallurgical Industry: For power transmission and control in high-temperature smelting equipment and heating systems.
  • Power Industry: For connecting lines in transmission lines, substations, and power equipment. These cables feature excellent insulation to prevent overheating.
  • Petrochemical Industry: For power and signal transmission in high-temperature equipment and pipelines in petrochemical plants, focusing on resistance to corrosive chemicals.
  • Automotive Industry: For electrical systems in car engines, exhaust systems, and other high-temperature components, often within complex wiring harnesses.
  • Electronics and Telecommunications: For wiring harnesses and cable assemblies in devices operating in high-heat environments, including coaxial and Ethernet cables.
  • Aerospace and Defense: For environments requiring high heat resistance, ensuring reliability and performance. These applications often use flexible and durable cables to withstand extreme conditions.

Performance Advantages

High-temperature cables offer significant advantages:

  • Strong Heat Resistance: They operate stably for long periods in high-temperature environments, less susceptible to insulation ageing and burning.
  • Excellent Corrosion Resistance: They resist oil, acids, alkalis, abrasion, etc., suitable for harsh environments. Materials like silicone and Teflon enhance these properties.
