silicon steel is used for transformer core because

dry type transformer is a completely stationary solid-state device and it needs less maintenance to provide problem-free service. This transformer doesn’t contain any moving parts. Not like liquid fill transformers, this transformer use simply high-temperature insulation systems as they are very safe environmentally. 

Definition of electrical steelElectrical steel, also known as silicon steel sheet, is an important soft magnetic alloy indispensable to power, electronics and military industry, as well as the largest output of metal functional materials, mainly used as the iron core of various motors, generators and transformers. Its production process is complex, manufacturing technology is strict, foreign production technology is protected in the form of patent, as the life of the enterprise. The manufacturing technology and product quality of electrical steel plate is one of the important signs to measure the development level of special steel production and science and technology in a country. At present, the quantity, quality and specification of cold rolled electrical steel in China cannot meet the needs of energy (power) industry development, and there is a big gap between China and Japan in terms of production technology, equipment, management and scientific research.

Embedded operating terminal can complete parameter setting quickly and conveniently.Application: Cut to Length Line machines are used for uncoiling, straightening of sheets and automatically feeding or even cutting in required lengths of sheets. Our product makes sure that the process is accurate and better shearing is done on processing line.This machine is special for transformer lamination manufacturing.

The consolidated experience in the production of resin transformers and the remarkable quality acquired has allowed the marketing, in addition to the complete transformer, also of low and medium voltage impregnated or encapsulated coils. The design for creation of the core can be provided by CANWIN or on the customer’s indications. This allows us to guarantee a reduction in transportation, import and construction costs of the transformer on site in distant countries.

A dry type transformer is a type of transformer which never uses any insulating liquid where its winding or core are immerged in liquid. Rather, the windings and core are kept within a sealed tank that is pressurized with air.
