Steel Sheet Cold Rolled EI 33 Transformer Core

Cold Rolled Electrical Steel Sheet EI 33 Transformer Core

Silicon steel sheet iron core is an iron-silicon alloy formed by adding a small amount of silicon (generally below 4.5%) to pure iron, which is called silicon steel. These iron cores have the highest saturation magnetic induction intensity value of 20000Gs; because of their good magnetoelectric properties, easy mass production, cheap price, little mechanical stress and other advantages, they are extremely widely used in the power electronics industry. Such as power transformers, distribution transformers, current transformers and other iron cores.
It is also the material with the largest amount of magnetic materials for power transformers. Especially suitable for low frequency and high power. Commonly used are cold-rolled silicon steel sheet DG3, cold-rolled non-oriented electrical steel strip DW, cold-rolled oriented electrical steel strip DQ, suitable for all kinds of electronic systems, household appliances, medium and small power low frequency transformers and chokes, reactor , Inductor iron core, this kind of alloy has good toughness, and can be processed by punching and cutting. The iron core has lamination type and winding type. However, the loss increases rapidly at high frequencies, and the general use frequency does not exceed 400 Hz.

Jiangyin hengtong was found in 1989.it is a large scale , standardization, consideration, and information all constitute important factors in the development of steel managing enterprises. The company located in jiangyin city-the NO.1 of the TOP 100 cities in China ,faces the shanghai on the east and near the changjiang river on the north ,with the ascendant geographical location and convenient transportation makes goods reach to destination very quickly.

Now we have two companies, jiangyin hengtong ,jiangsu smart motor technology（jiangsu shuaijin） ,about 200 employees ,30% of them is professional and technical talents.jiangyin hengtong is as a window of the group . it got the ISO9001 ROHS SGS ISO14001 IATF16949 and the horner of jiangyin high-tech enterprise,jiangyin key enterprise . it covers about 1300 are and has two set of slitting machine , twelve sets of annealing equipment .more than 50 sets of punching machine and cutting machine.
