High Temperature Resistant Cable Model Specifications Abstract: High temperature resistant cables are essential in industries where extreme heat is present. These cables are designed to withstand high temperatures and provide reliable performance in challenging environments. In this article, we will explore the model specifications of high temperature resistant cables from four aspects: conductor material, insulation material, jacket material, and temperature rating. 1. Conductor Material The conductor material used in high temperature resistant cables plays a crucial role in their performance. Typically, these cables use conductors made of materials such as nickel-plated copper or silver-plated copper. These materials offer excellent conductivity and can withstand elevated temperatures without significant degradation. Nickel-plated copper conductors are widely used due to their corrosion resistance and ability to handle high temperatures up to 200°C or more. Silver-plated copper conductors have even better conductivity but may be limited to lower temperature ranges due to the potential for oxidation at higher temperatures. In addition to the choice of conductor material, the size or gauge of the conductor also affects the cable's overall performance. Larger gauge conductors can carry higher currents without excessive heating, making them suitable for applications that require power transmission over long distances. 2. Insulation Material The insulation material used in high temperature resistant cables is specifically chosen for its ability to withstand extreme heat without melting or degrading over time. Common insulation materials include fluoropolymers like PTFE (Polytetrafluoroethylene) and FEP (Fluorinated Ethylene Propylene). PTFE is known for its exceptional thermal stability and resistance against chemicals and moisture. It can operate reliably at temperatures ranging from -200°C up to 260°C, making it ideal for applications where exposure to extreme heat is expected. FEP shares similar properties with PTFE but has a lower maximum operating temperature of around 205°C-210°C while still providing excellent thermal stability and chemical resistance. 3. Jacket Material The jacket material serves as an outer protective layer for high-temperature resistant cables, providing mechanical strength and protection against external factors such as abrasion, chemicals, oils, UV radiation, etc. Commonly used jacket materials include silicone rubber (SiR), ethylene propylene diene monomer (EPDM), polyurethane (PUR), or fiberglass braiding with an impregnation coating. Silicone rubber jackets offer outstanding flexibility even at low temperatures while maintaining their integrity at elevated temperatures up to 180°C-200°C range depending on specific formulations. EPDM jackets provide good resistance against weathering elements like ozone exposure while offering decent thermal stability within a range of approximately -50°C up to 150°C. Polyurethane jackets exhibit excellent abrasion resistance along with good flexibility across a wide range of operating conditions (-40 °C up t
