High-temperature and heat-resistant cables are widely used in critical industries such as aerospace, energy, steel manufacturing, motor systems, and construction. These cables are designed to operate continuously at temperatures ranging from 125°C to 250°C, making them essential in environments where standard cables would fail. Common types of high-temperature resistant cables include those insulated with Polyether Sulfone (PES) and Polyetheretherketone (PEEK).
PES-insulated wires are known for their excellent thermal stability, especially in environments with significant temperature fluctuations. They maintain consistent performance under high heat and offer strong mechanical strength, electrical insulation, and long-term reliability.
PEEK-insulated cables, on the other hand, are made from a high-performance thermoplastic that can withstand continuous operation at up to 250°C. PEEK is also flexible, has good creep resistance, and is self-extinguishing, making it ideal for applications where fire safety is a concern.
In addition to high-temperature cables, there are specialized cables designed for specific functions. Low-inductance cables are used in both high-power and low-power applications. Modern versions include connectors fixed directly onto the cable, with positive and negative conductors housed within an outer sheath for improved performance and durability.
Low-noise cables, often referred to as shock-proof instrument cables, are designed to minimize internal noise generation. Under conditions like bending, vibration, or impact, these cables produce less than 5 mV of pulse signal. Noise can arise from factors such as changes in dielectric properties, molecular friction, or piezoelectric effects. They are commonly used in medical and industrial settings for precise small signal measurements.
Environmental protection has also become a key focus in the cable industry. Green cables, such as CMP-rated cables and halogen-free wires, are gaining popularity due to their safety and eco-friendly properties. CMP cables meet the highest UL flame retardant standards, while halogen-free cables reduce toxic emissions during combustion.
With the release of the "Twelfth Five-Year" development plan for the domestic wire and cable industry, the sector has undergone significant restructuring. As a result, many companies have experienced rapid growth, and the demand for specialized cables is expected to rise substantially in the coming years. This shift not only drives innovation but also creates new opportunities for sustainable and high-performance cabling solutions.
