Distribution Transformer with Amophous Coil Low Loss

Three phase amorphous coil distribution transformer with standard fully complied with IEC60076, GB1094-1996

Amorphous Alloy Material Introduction

Amorphous alloy material is a low-loss transformer, using a novel energy-saving material. Amorphous alloy strip with iron as the basic elements tighter with silicon and other elements. Under certain conditions melting using ultra rapid cooling technique and spraying it directly into the cooling rollers to cast thin.

Amorphous Alloy Material Characteristics

(1) Material is thin, the thickness only 0.025mm, 1/10 of silicon steel

(2) High resistivity is about three times as the silicon steel belt

(3) Non- directional of crystalline arrangement

(4) High frequency usually a few thousａnd Hertz

(5) Iron loss is small at 1.35T, the loss is only 0.21W/kg ,65% smaller than ordinary silicon steel

Transformer Special Service Condition

The height above sea level is above 1000m;
