We offer electric current transformer core nano crystalline core. 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 cores 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 shell is made of abs, pc, aluminum or copper. 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. Ps:customized models available
