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
- High quality iron core 45° full oblique joint step laminated structure
The iron core
- The core is made of high quality cold rolled grain oriented silicon steel sheet insulated by mineral oxide
- Minimize loss level, no-load current and noise by controlling the cutting and stacking process of silicon steel sheet
- Apply class F or CLASS H core paint on the surface of assembled cores 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
- The whole winding is heated in the oven to 140°C and polymerized for 4 hours. It has excellent corrosion resistance of industrial gas
High voltage winding
- Made of insulated copper wire and using the patented technology of Hengfengyou Electric
- For small volume products, the high voltage winding uses a linear voltage gradient from top to bottom
- For products with large capacity, the high voltage winding is made by "tape winding" technology
- 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
- Baosteel, Wisco silicon steel sheet
- 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.
