Foil Winding Machine BRJ-1400-2: This foil winding machine has unique appearance, convenient operation, intuitive data display, high degree of automation, and is well received by users. This foil winding machine is widely used in oil-immersed transformer, dry transformer, special transformer and reactor production required.Foil coils are of different thicknesses copper or aluminum foil as a conductor, with wide ribbon insulation material as the insulation between layers, with narrow ribbon insulation material as the end insulation, completed winding one time, forming a coil. The inner and outer leads of the coil are welded and wrapped up at the same time.

CAH(23)-300/400/600DV:  Cut to length lines are designed for sheet metal production by leveling and cutting a mother coil into cross sections, creating completely flat formats that are properly stacked. The basic process of cut to length lines comprises unwinding, levelling, cross cutting, stacking and packaging. The cut-to-length-line is a special equipment for the production of transformer core, is our latest generation of cross shear line. This cut to length production line is used for shearing, O punching and V notch of transformer core sheet.The special point of this ctl line is that one O punch and two V notch can work for York-sheet with two floor stacking; Can produce transformer core pieces with 3, 5, 7 steps in vertical direction and 3, 5, 7 steps in horizontal direction.After the coil material of silicon steel sheet is punched and cut into certain shape and size by this cut to length production line, the classification and finishing work is completed at the end of the production line, and it is automatically stacked into 2 columns and used for the core assembly.This cut to length production line adopts advanced control system to ensure the accurate and stable operation of the production line. 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.

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.

The high and low voltage windings are all cast epoxy resin and cured in vacuum, forming a high strength FRP body structure.The temperature sensor PT100 platinum resistor is inserted into the low-voltage winding to obtain the temperature signal.

dry type transformer is widely used in local lighting, high-rise buildings, airports, terminals CNC mechanical equipment and other places, simply said dry transformer refers to the core and winding are not impregnated in the transformer insulation oil.

A dry type transformer does not have any rotating parts; it is a motionless device that utilizes eco-friendly temperature insulation systems. This type of transformer is also named as “cast resin type transformers”. It is used in various commercial, industrial, as well as utility applications.
