Dry bushing vacuum casting equipment

Performance characteristics of vacuum casting equipment for high-voltage dry-type bushings

→The unique vacuum degassing tank structure is particularly suitable for large-capacity, single-component, low-viscosity materials, with a wide capacity range. For materials with extremely low viscosity, thin-film degassing technology can still be employed, ensuring thorough and rapid degassing of the castable, which is beneficial for both partial discharge performance and appearance quality.

→ The entire equipment is controlled using a centralized control cabinet, computer, and PLC, with modular control processes. The operation status of the entire equipment is displayed and recorded. The equipment is easy to operate, the process is reliable and controlled, and maintenance is convenient.

→An electronic scale automatic batching system with high reliability, controlled by PLC, allows for the setting and modification of casting material formulas on a computer.

→ Full vacuum operation

Component A (resin) and Component B (curing agent) are introduced into the pre-mixing tank through vacuum suction, with the quantity of material entering and exiting automatically measured and controlled by an electronic scale. This ensures that the cast products meet the production process requirements throughout the entire production process, while significantly improving the working environment and reducing work intensity.

The vacuum system utilizes a high-temperature rotary vane vacuum pump from Leybold as the backing pump, which exhibits excellent resistance to resin vapor. Coupled with a vacuum transmitter from Leybold and a cooling and filtering device from Shenrui, the system ensures accurate measurements and long-term stable operation.
