ULJ-105 W40 105℃ UL Standard SJTW Insulation Compound Rated For Cables

ULJ-105 W40 105℃ UL Standard SJTW Insulation Compound Rated For Cables is an insulation material designed for electrical applications requiring high heat resistance. Complying with UL (Underwriters Laboratories) standards, it has heat resistance and works stably in environments up to 105°C. SJTW insulation material has electrical insulation properties, as well as waterproof, flame retardant, anti-aging, wear-resistant and other properties. It is suitable for applications such as outdoor engineering, electrical equipment, lighting and large mechanical power distribution. This kind of insulation material can ensure the safe operation of electrical equipment in harsh environments.
