Introduction to High – temperature Cables
High – temperature cables are specialized cables designed to operate reliably in environments with elevated temperatures. These cables are engineered to withstand extreme heat without compromising their electrical conductivity, insulation properties, or mechanical strength. They are widely used in various industries such as aerospace, power generation (especially in nuclear and thermal power plants), steel manufacturing, and chemical processing. The materials used in high – temperature cables are carefully selected to resist degradation under high – heat conditions. Common insulation materials include mica, ceramic fiber, and PTFE (polytetrafluoroethylene), and conductors are often made of high – purity copper or nickel – based alloys. High-temperature Cables
