ZJBF Electrical Insulation Materials Technology Corporation is committed to the research, development and production of high performance electrical insulation materials for motors, generators, transformers and other polymer composites.
In the field of high-performance electrical insulation materials, it is China's invisible champion enterprise.
The company has a relatively complete product system of insulating materials, including insulating resin, high-strength slot wedge, insulating sleeve, binding wire/rope/tape, mica products, composite materials, thermal expansion materials and other insulating materials.
The company has the batch production capacity of insulation materials of various heat-resistant grades, such as B, F, H, C and above, and can provide customized products according to customers' differentiated needs.
It provides systematic solutions for the application of insulation materials in wind power generation, rail transit, industrial motors, household appliances, new energy vehicles, hydropower and other fields.
The company has outstanding competitive advantages and independent innovation ability in the research, development and manufacturing of insulating materials. It has established provincial research institute of electrical insulating materials, provincial academician expert workstation, provincial postdoctoral workstation and other research and innovation platforms, and has established joint research and development platforms with Zhejiang University, Harbin University of Industry, and other well-known Chinese universities.
The company has 57 invention patents and 31 utility model patents, and has passed ISO9001, IATF16,949, ISO14,001 and ISO45,001 management system certification.
ZJBF has participated in the drafting of many national, industrial and group standards, such as the national standard for thermal resistance of electrical insulating materials, the national standard for dielectric and resistance characteristics of solid insulating materials, and the industrial standard for water-soluble semi inorganic silicon steel sheet paint, and has successively undertaken the industrialization demonstration project of the National Torch Plan.
The rail transit traction motor insulation system and wind turbine insulation system independently developed by the company have the strength to compete with international large companies. The company actively develops high-end insulation material markets such as rail transit, wind power generation and new energy vehicles.
In the field of rail transit, ZJBF has successively developed silicone impregnating varnish and aramid reinforced mica tape suitable for its vacuum pressure impregnation process in the process of localization substitution of insulation materials and insulation systems for rail transit traction motors, with the goal of developing solvent-free silicone insulation systems with high heat resistance, to solve the localization problem of two core materials of silicone insulation systems.
At the same time, the company has completed the development of insulation materials with excellent heat resistance, electrical performance and good compatibility with silicone resin, such as polyimide based glass fiber reinforced molded slot wedges and aramid binding tapes, which enable the company to provide high-performance insulation materials for high-speed railway traction motors with independent intellectual property rights in China.
In the field of wind power, the environment-friendly wind power VPI impregnating varnish insulation products developed by ZJBF have been successfully applied to the first 8.0MW direct drive permanent magnet wind turbine in China and the first 12MW semi direct drive permanent magnet synchronous wind turbine in the world.
