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
Meet environmental requirements: The insulation material used in
VPI process is environmentally friendly, non-toxic, and recyclable,
in line with the production concept of green environmental
protection, and meets increasingly strict environmental
requirements.
