UL3572 Silicone Wire 1000V 200°C High Temperature Flexible Silicone Insulated Electrical Wire

UL3572 Silicone Wire is a high-performance, heat-resistant electrical wire designed for internal wiring in demanding high-temperature and precision electronic environments. Featuring premium silicone rubber insulation and high-conductivity copper conductors, this wire delivers excellent flexibility, thermal stability, and long-term reliability in harsh operating conditions.

According to the referenced product data, UL3572 silicone wire supports a rated voltage of up to 1000V AC and operates reliably within a wide temperature range from -40°C to +200°C, making it ideal for high-heat and continuous-duty applications.

The conductor structure is optimized for performance and durability: nickel-plated copper is used for smaller diameters (below 0.38 mm) to enhance oxidation resistance, while larger diameters utilize tin-plated copper for stable electrical conductivity and corrosion resistance.

With excellent dielectric strength, soft insulation, and precise diameter tolerance, UL3572 wire ensures easy stripping, installation efficiency, and superior electrical safety. It is widely used in advanced industries such as EV systems, robotics, medical devices, industrial machinery, and AI data centers where high flexibility and heat resistance are critical.
