Why Choose Our 35kV Three-phase Epoxy Cast Dry Distribution Transformer？

Leading Technology

• High pressure copper tape winding – Flame retardant formula, vacuum pouring

• Low pressure copper foil winding – Thermosetting epoxy prepreg cloth insulation

• High quality iron core – 45° full oblique joint step laminated structure

The Iron Core

• Made of cold rolled grain oriented silicon steel sheet with mineral oxide insulation

• Precision cutting and stacking minimizes loss, no-load current, and noise

• Class F or Class H core paint prevents corrosion and rust

Low Voltage Winding

• High quality copper foil with thermosetting epoxy prepreg cloth insulation

• Excellent insulation resistance and radial stress resistance against short circuit

• Tinned copper bar outgoing terminal

• Oven heated to 140°C for 4 hours – excellent industrial gas corrosion resistance

High Voltage Winding

• Insulated copper wire with Hengfengyou Electric patented technology

• Small volume: linear voltage gradient from top to bottom

• Large capacity: tape winding technology

• Extremely low electric field between adjacent conductors

• Reliable structure during operation and transportation

Key Advantages

• Copper tape + copper foil winding, flame retardant vacuum casting

• 45° full oblique joint core – low loss, low noise
