Epoxy Resin Transformer Busgings

Advantages: No risk of fracture, maintenance-free, lightweight, and excellent sealing performance.

Limitations: The maximum temperature resistance is slightly lower than that of porcelain bushings, making it unsuitable for ultra-high voltage and extra-high voltage applications.

Epoxy resin transformer bushings are insulating bushings manufactured with epoxy resin as the main insulating material through vacuum casting and curing processes.

They are mainly used for external insulation and fixation of transformer conductive rods, and are primarily suitable for dry-type transformers.

The vacuum pressure casting process effectively eliminates internal air bubbles. Combined with reinforcing fibers to improve mechanical properties, the product is molded through high-temperature curing to ensure compactness.
