Epoxy Resin Cast Dry-Type Transformer
This dry-type transformer features an epoxy-cast design, enhancing its structure and manufacturing process. The unit's coils are vacuum-cast and the iron core uses fine quality silicon-steel sheets to reduce power consumption and noise.
Technical Specifications
Overview
High-Performance Epoxy Resin Dry-Type Transformer
This epoxy resin cast dry-type transformer is engineered for high reliability and environmental safety in demanding B2B power distribution applications. Featuring advanced vacuum casting technology and high-quality silicon-steel cores, it offers exceptional fire resistance, low partial discharge, and high mechanical strength. Designed for sustainability, up to 90% of the transformer materials are recoverable at the end of its long service life.
Core Technology
Iron Core Construction
- Precision cut silicon-steel sheets (burr < 0.02mm)
- Five-stage stepping joint for adjustable clamp force
- H-insulated oil-lines for internal cooling
- Double H-glue application for long service life
- Elastic bearing assembly for high shock resistance
