VPI Vacuum pressure impregnation equipment

Vacuum pressure impregnation equipment (VPI) is an advanced process equipment widely used for insulation treatment of electrical products such as motors, transformers, capacitors, etc. It significantly improves the electrical performance, mechanical strength, and environmental resistance of the product by creating a vacuum and pressure environment that deeply penetrates the insulation material into the internal voids of the product.

Advantages of VPI devices:

Excellent insulation performance: The VPI process can fully fill every tiny gap inside the product with insulation material, effectively eliminating bubbles and defects, forming a dense and uniform insulation layer, significantly improving the electrical strength, withstand voltage level, and partial discharge performance of the product.

Enhanced mechanical strength: After impregnation and curing, the insulation material can tightly bond with the product body, forming a sturdy overall structure, effectively improving the mechanical strength, seismic performance, and impact resistance of the product, and extending its service life.

Excellent environmental resistance: The VPI process can effectively prevent the invasion of harmful substances such as moisture, dust, salt spray, etc., improve the moisture, mold, and corrosion resistance of the product, and enable it to operate stably in harsh environments.

Efficient production efficiency: VPI equipment adopts an automated control system, which can achieve mass production, improve production efficiency, and reduce labor costs.

Environmental protection and energy conservation: The insulation material used in VPI process is environmentally friendly, non-toxic, and recyclable, in line with the production concept of green environmental protection.

Main parameters of VPI equipment:

Vacuum degree: up to 10 ^ -3 Pa or above, ensuring sufficient elimination of air inside the product.

Pressure range: usually 0.4-0.8 MPa, can be adjusted according to different product requirements.

Immersion temperature: Set according to the characteristics of the insulation material, usually between 50-120 ℃.

Curing temperature and time: Set according to the curing characteristics of the insulation material to ensure sufficient curing.

Equipment capacity: Different specifications of equipment can be selected according to production needs, ranging from small laboratory equipment to large industrial equipment.

Application industries of VPI devices:

Motor industry: Used for insulation treatment of motor stator, rotor, coil and other components to improve the efficiency, reliability and service life of motors.

Transformer industry: Used for insulation treatment of transformer coils, iron cores and other components, improving the insulation level, short-circuit resistance and heat dissipation performance of transformers.

Capacitor industry: used for impregnation treatment of capacitor cores to improve the withstand voltage level, capacity stability, and service life of capacitors.

Other industries: It can also be applied to insulation treatment of electrical products such as reactors, transformers, and high-voltage switches.

Reasons for choosing VPI devices:

Improving product quality: The VPI process can significantly improve the electrical performance, mechanical strength, and environmental resistance of products, making your products more competitive in the market.

Reduce production costs: VPI equipment can achieve mass production, improve production efficiency, reduce labor costs, while reducing material waste and lowering production costs.

Extend product lifespan: VPI technology can effectively extend the service life of products, reduce maintenance and replacement frequency, and lower the long-term usage cost for users
