Product Introduction of Epoxy Resin Cast Transformer
The Epoxy Resin Cast Dry-type Transformer is specifically designed for high-security and high-load scenarios, with a capacity range of 30-2500KVA. It uses fully enclosed epoxy resin casting technology to achieve zero oil-gas emissions, fireproofing, and low-noise operation, meeting global safety standards (UL/IEC). Suitable for data centers, rail transit, medical centers, and other environments with strict requirements for fire protection and stable power supply, it is an ideal alternative to traditional oil-immersed transformers.

Product production process
The production process of the Epoxy Resin Cast Dry-type Transformer strictly follows ISO 9001 standards:
Core Material Selection:
High-quality copper wire, high-grade silicon steel sheets, and epoxy resin selected and certified by SGS.
Precision Winding:
CNC winding machines accurately wind coils, ensuring less than 0.5% error in turns, improving heat dissipation efficiency.
Vacuum Casting Curing:
Coils and cores are cast with epoxy resin under vacuum conditions, eliminating bubbles and forming an integrated sealed insulation layer.
Secondary Impregnation Treatment and Strict Testing Before Shipment:
Vacuum Pressure Impregnation (VPI) process further enhances electrical insulation and mechanical strength.Tested for withstand voltage (200% rated voltage), partial discharge (<10pC), and temperature rise, issuing CE and TUV certification reports to ensure zero defects.
