UL1858 High-Temperature Resistant Wire is a PFA insulated single core wire in the UL AWM (Appliance Wiring Material) standard. The rated voltage of UL1858 High-Temperature Resistant Wire is 300V, and the conductor specifications cover 10-30 AWG. Its core characteristics are high and low temperature resistance and chemical corrosion resistance (strong acid, strong alkali resistance), as well as excellent electrical insulation and flame retardancy. It is widely used for internal wiring of equipment with strict temperature and environmental requirements, such as aerospace, petrochemicals, precision instruments, and home appliances (such as microwave ovens, air conditioners).

Application
Power equipment lead out line
In the internal connections of transformers, motors, and power equipment, UL1858 High Strength Resistance Wire is often used as a lead wire. Its good insulation strength (rated voltage 300V) and corona resistance can withstand instantaneous overvoltage and long-term electromagnetic vibration during motor start-up, preventing equipment failure caused by insulation breakdown.
Strict environment and specialized industries
UL1858 High Strength Resistance Wire is used as a special wiring material in aerospace, automotive engine compartments, and petrochemical equipment. In the vicinity of aircraft or high-temperature furnaces, wires need to simultaneously cope with extreme cold and hot alternation and mechanical vibration; In automotive engine compartments or metallurgical equipment, it is necessary to withstand oil pollution and high temperatures.
Industrial sensing and precision instruments
In industrial automation and process control, UL1858 High Strength Resistance Wire is commonly used as a lead for temperature sensors (such as thermocouples), thermistors (PTC), and pressure transmitters. Its PFA insulation material has strong chemical inertness and can resist oil stains, weak acids, weak bases, and solvent corrosion in industrial environments, ensuring the stability of signal transmission.
