Epoxy resin dry-type transformer

At the core of every epoxy resin dry-type transformer lies a precise and critical process: vacuum casting. In a highly controlled clean environment, epoxy resin is gradually infused into every minute space within the winding using specialized vacuum casting equipment. This process, conducted under negative pressure, thoroughly eliminates air bubbles and impurities, allowing the resin to form a seamless, solid insulation layer that fully encapsulates the conductors.

Vacuum casting is not merely a step in manufacturing—it is a commitment to quality:

• Void-Free Insulation: Prevents partial discharge, extending service life by over 30%;

• Exceptional Stability: Resists humidity, dust, and chemical corrosion, operating reliably in temperatures from -40°C to 155°C;

• Safety & Eco-Friendliness: Free from combustible materials, emits no toxic gases, and runs silently;

• Compact Design: Cast construction reduces volume by up to 20% compared to conventional models, allowing flexible installation.

From power distribution systems to rail transit and renewable energy plants, vacuum-cast epoxy resin transformers are increasingly chosen for their maintenance-free operation, enhanced safety, and long service life.

Choose it for energy transmission that stands the test of time.
