Product advantage

> Leading technology
 - High pressure copper strip winding technology, flame retardant formula vacuum pouring

 - Low pressure copper foil winding technology, thermosetting epoxy prepreg cloth insulation
 - High quality iron core 45° fully oblique joint step laminated structure

The iron core
 - The core is made of high quality cold-rolled grain oriented silicon steel sheet with mineral oxide insulation
 - By controlling the cutting and stacking process of silicon steel sheet, the loss level, no-load current and noise can be minimized
 - The surface of the assembled core is sealed with grade F or grade H core paint to prevent dust and corrosion

Low voltage winding
 - The low voltage winding is made of high quality copper foil
 - The insulation between layers is made of thermosetting epoxy prepreg cloth
 - The ends of the windings are insulated with thermosetting epoxy prepreg cloth
 - Excellent insulation resistance
 - It has very good ability to bear radial stress caused by short circuit
 - The outlet terminal of low voltage winding is tin-plated copper bar
 - The whole winding is placed in the oven and heated to 140°C. After 4 hours of polymerization, it has excellent corrosion resistance to industrial gases

High voltage winding
 - Woven with insulated copper wire, and applied by hengfengyou electric exclusive patent technology
 - For small volumes, the high voltage winding uses a linear voltage gradient from top to bottom
 - For large-capacity products, the high-voltage windings are wound by "band winding" technology
 - The application of these methods causes the electric field between adjacent conductors to be very low
 - The transformer has a firm structure during normal operation and transportation

High quality material
 - Baosteel, WISCO silicon steel sheet
 - China produces high quality oxygen free copper
 - Swiss Huntsman epoxy resin (with flame retardant filler)

Patent technology
 - The high pressure coil is cast under high vacuum, and the casting material system is added with a unique flame retardant filler, which is a patented technology of Hengfengyou Electric.When the transformer is exposed to the flame, the transformer will die out immediately.With a unique and excellent flame retardant characteristics and the ability to adapt to harsh working environment.
