Product advantages
Leading technology
- High pressure copper tape winding technology, flame retardant formula vacuum pouring
- Low pressure copper foil winding technology, thermosetting epoxy prepreg cloth insulation
- Adopt three-phase five-column structure, frame structure around iron core protection
- Strong heat dissipation, low temperature rise, can operate at 150% rated load under air cooling conditions
The iron core
- Iron core assembled with high quality amorphous alloy silicon steel sheet
- Achieve very low loss (75% lower than GB/T10228 standard) through the control of silicon steel sheet shearing and stacking process
- The surface of the core is sealed with class F or CLASS H core paint to prevent corrosion and rust
Low voltage winding
- The low voltage winding is made of high quality copper foil
- Insulated by thermosetting epoxy preimpregnated cloth
- Winding ends are insulated with thermosetting epoxy preimpregnated cloth
- Excellent insulation resistance
- Very good resistance to radial stress caused by short circuit
- The outgoing terminal of the low-voltage winding is tinned copper bar
High voltage winding
- Made of insulated copper wire and using the patented technology of Hengfengyou Electric
- The application of these methods makes the electric field between adjacent conductors very low
- Transformer structure is reliable during normal operation and transportation
High quality material
- Silicon steel sheet from China Wisco
- China produces high quality anaerobic copper
- Huntsman Epoxy resin (including flame retardant filler)
Patent technology
- The high voltage coil is molded under high vacuum, and the castable material system adds a unique flame retardant filler, which is a patented technology of Hengfengyou Electric. When the transformer is exposed to flame, it will immediately self-extinguish. With unique and excellent flame retardant characteristics and the ability to adapt to bad working environment.
