Current Transformer Core with DMC

Power current transformer is a special transformer for measuring current of power transmission and distribution lines. The measurement precision differs from soft magnetic materials it uses. The higher precision (less measurement error) is, and the higher core permeability requires. When cold rolling silicon steel sheet cannot reach the requirement of little transformation ratio and low ampere turns, it has to use soft magnetic material with high permeability, such as perm alloy and amorphous alloy. Amorphous alloy has the similar initial permeability as perm alloy, higher maximum permeability, good temperature stability, and 70%-75% lamination coefficient. In the same size and performances, amorphous core's weight is only two thirds of perm alloy core, and price is more competitive. In recent years, the demand of high-precision transformer (such as grades 0.2, 0.2S and 0.5S) has rapidly increased. Therefore, domestic demand of amorphous alloy measurement current transformer core rapidly increases.

The core casing is made of ABS, PC, DMC,aluminum or steel.
Rated voltage class: 0.5, 10, 15, 20, 35, 63, 110, 220, 330, 500, 1,100 KV
Transformer precision class: 0.5, 0.5s, 0.2, 0.2s, 0.1, 0.02, 0.01.

The company has large production capacity, timely supply and various specifications, and can deliver goods in three days.
Besides, we can design current transformers and provide current transformer test report.
Performance Comparison of amorphous, Perm alloy and Silicon Steel:

At this stage, more than 7000 modes are available in our manufactory and each has dozens of inner,outer and height specifications,( the height ranges from 10 without any top limitation) and finished products(protecting box is made of metal aluminum). You have lots of options

Note:
1. The existing mold if it can not meet customer needs, we immediately open mold according to customer demand production.
2. Rectangular, U-type, oval and other special graphics core, the company, plasma, cutting machine mechanical equipment, according to customer's drawings.
