The three phase dry type transformer adopts a fully sealed three-phase dry structure design, ensuring voltage balance and load stability. It is suitable for industrial distribution, power systems, and other fields.
High efficiency and energy saving:
Optimized electromagnetic calculations and low-loss silicon steel sheet selection significantly reduce no-load losses and load losses, meeting international energy efficiency standards.
Environmental protection insulation system:
Non-polluting resin insulation materials replace the traditional oil-immersed design, completely avoiding oil leakage risks and complying with environmental regulations.
Core Composition Winding System
Cast resin windings: The high-voltage winding of the cast resin dry type transformer uses epoxy resin vacuum casting technology, enhancing mechanical strength and insulation performance while adapting to high-temperature and humid environments.
Low-voltage winding: Made from copper foil winding, reducing eddy current losses and improving heat dissipation efficiency.
Core Structure:High-quality cold-rolled silicon steel sheets are stacked using a 45° full oblique seam process, reducing noise and vibration, and lowering no-load losses by over 20%.
Heat Dissipation and Protection:Forced air cooling design, combined with high-temperature resistant and flame-retardant outer shells (IP23 protection level), ensures stable operation of the dry type transformer in harsh environments.
Manufacturing Process of cast resin dry type transformer
Raw Material Quality Inspection:
Strict testing of silicon steel sheets, copper materials, and resin materials to ensure material purity and performance meet standards.
Winding Production:Automated winding machine for precise control of turns and wire spacing, followed by vacuum impregnation curing to form the core components of the cast resin dry type transformer.
Core Assembly:Fully automatic stacking equipment ensures tight bonding of the core, reducing magnetic circuit losses.
Final Assembly and Testing:Modular assembly process integrates windings, core, and temperature monitoring systems. Afterward, tests such as three-phase unbalanced load testing (to verify the performance of the three phase dry type transformer), partial discharge testing, and withstand voltage testing are conducted to ensure product reliability.
