Power transformer insulation materials are core components that determine equipment safety, temperature resistance and service life. For a long time, the high-end thermally upgraded insulation paper market has been monopolized by imported brands, resulting in high procurement costs, long delivery cycles and insufficient supply flexibility for transformer manufacturers. With the continuous upgrading of domestic power equipment manufacturing standards, high-performance localized insulation materials have become an inevitable trend. Thermally Upgraded Kraft Paper launched by Hanyao breaks the technical barrier of imported products, providing a cost-effective and stable alternative solution for power and distribution transformer insulation.
The product supports long-term stable operation at 120°C, solving the aging and failure problems of ordinary kraft paper under high-temperature working conditions, and effectively extending the overall service life of transformers.
Made of 100% electric-grade unbleached pulp, it features stable electrical strength, qualified water extract conductivity and pH value, as well as outstanding tensile and tear resistance. It fully meets the winding stability requirements of power transformers.
The nitrogen content is stably controlled at 1.1%-2.3%, and the tensile strength aging residual rate is up to 75%. The overall performance indicators are fully comparable with imported high-end insulation paper.
As a mature domestic alternative material, it eliminates the premium cost of imported products. With complete stock specifications and flexible customization services, it greatly shortens the delivery cycle and optimizes the procurement cost for transformer manufacturers.
