Cold Rolled EI Lamination Core Silicon Steel

Cold Rolled EI Non Oriented Silicon Steel Sheet Transformer core

The general part of the commonly used transformer core is made of silicon steel sheet. Silicon steel is a kind of silicon (silicon also known as silicon) steel, and its silicon content is in. 0.8% ~ 4.8%. The core of the transformer made of silicon steel is because silicon steel itself is a magnetic substance with strong magnetic permeability. It can generate a large magnetic induction intensity in the energized coil. This can reduce the size of the transformer. The transformer is in AC state [The power loss is not only in the resistance of the coil. It also occurs in the iron core under the alternating current magnetization. The power loss in the iron core is usually called ‘iron loss’. Iron loss is caused by two reasons, one is ‘hysteresis loss’ and the other is ‘eddy current loss’.
Hysteresis loss is the iron loss caused by the presence of hysteresis during the magnetization of the iron core. The size of this loss is proportional to the area surrounded by the hysteresis loop of the material and is narrower than the hysteresis loop of silicon steel The hysteresis loss of the iron core used as a transformer is small, which can greatly reduce the degree of heat generation.

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.
