Automatic Vacuum Epoxy Resin Pressure Casting Equipment for Dry-Type Transformer Coils (≤35kV / 3000kV Class)

YIBO's Automatic Vacuum Epoxy Resin Casting Equipment is the most advanced solution for vacuum pressure casting of dry-type transformer coils and related electrical components. It integrates automatic batching, thin-film degassing, dynamic mixing, and precision vacuum casting into one fully automated production line. With a 300L resin/curing agent degassing system, 600L/S vacuum pumping, and a Φ2800×3500mm casting tank, it achieves working vacuum of 100–300 Pa and limits leakage to ≤50 Pa·L/S. The HMI provides real-time process monitoring and recording, ensuring high product quality, reduced labor intensity, and efficient, clean manufacturing for transformer and reactor insulation.

Description

1. Core Features & Advantages

① Advanced Dynamic Mixing Technology

Employs cutting-edge dynamic blending for uniform, high-efficiency mixing without pollution. Easy to clean, ensuring consistent epoxy resin quality and reliable insulation performance.

② Automatic Batching & Precision

After A/B material degassing, automatic batching by set mixing ratio reduces labor intensity and supports civilized production. Ingredient error is strictly controlled within ≤±0.3 kg.

③ Thin-Film Degassing & Vacuum Control

Thin-film degassing with settable vacuum degree and automatic control avoids long-term high-vacuum evaporation of effective components, preserving resin properties and enhancing casting reliability.

④ High Automation & HMI Control

PLC-based high automation with advanced human-machine interface (HMI). Real-time process monitoring and recording for traceability and quality assurance throughout the casting cycle.

⑤ Complete Integrated System

Includes resin/curing agent mixing degassing tanks, electronic scale metering, final mixing tank, vacuum casting tank, heating, vacuum, cooling water, pneumatic, control systems, and steel platform—all engineered for seamless operation.
