Looking for superior insulation for high-temperature transformers? Our high-performance polyimide paper is engineered for extreme environments. Supporting continuous operation from 210C to 280C, this Class C insulating material outperforms traditional aramid papers by preventing dielectric attenuation and shrinkage. With a dielectric strength of 15kV and exceptional mechanical toughness, it is the perfect solution for dry-type and oil-immersed transformers, rail transit, and power converters. Ensure long-term reliability and safety for your electrical equipment. Contact us today for custom slitting options and technical specifications to upgrade your transformer insulation performance.
