Description

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;
