Introduction
Dry-type transformers are widely used in local lighting, high-rise buildings, airports, docks, CNC machinery and equipment, simply put, dry-type transformers refer to transformers whose cores and windings are not impregnated in insulating oil.
It is mainly composed of an iron core composed of silicon steel sheet and an epoxy resin cast coil, and an insulating cylinder is placed between the high and low voltage coils to increase electrical insulation, and the coil is supported and constrained by a gasket, and the fasteners of its parts lap have anti-loosening performance.

Technical Data
Structure Features
1. The magnetic core has a miter step joint to ensure optimum performance and minimum sound levels by using step lap technology.
2. Windings are casted under vacuum with epoxy resin. Transient analysis tests have been performed to verify the electrical stress distribution
3. Air-cooling system adopts top-blowing cross flow fan, which has the characteristics of low noise, high wind pressure, beautiful look, etc.
4. Intelligent temperature controller improves the safety and reliability of the transformer.
5. Supply various Enclosure options in IP20, IP23, etc.,
