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.

1) Two sets of V-shaped shearing machines and three sets of hole punching machines. The three punching mechanism adopts a chasing shear design, which can move vertically and horizontally, automatically arrange positions, and easily achieve three simultaneous steps and five synchronous cutting;2) The material handling part adopts a gantry type servo belt mechanism, which can automatically rise and fall with the change of stacking height;3) Equipped with a stacking electric trolley, the trolley can move left and right, the upper stacking platform can be lifted and lowered, and even workshops without truss cars can produce iron cores!4) The shear bed section has added a four wheel drive micro tension servo pulling mode, and cutting of materials with different thicknesses of 0.15-0.35 mm does not require changing the cutting parameters!

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.

CAH(22)-300-400-600DT: The cut-to-length-line is a special equipment for the production of transformer core, is our latest generation of cross shear line. This production line is used for shearing, O punching and V notch of transformer core sheet.The special point of this line is that one O punch and one V notch；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 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 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.

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. 

CANWIN's transformer core is made of high magnetic conductivity high-quality grain oriented cold rolled silicon steel sheets, with 45 ° fully oblique step seams.The iron core adopts a special square tube pull plate structure, the core column is bound with insulation tape, and the surface of the iron core is coated with special resin to prevent moisture and rust, effectively reducing no-load loss, no-load current, and iron core noise.Built Cores  compared with similar products on the market, it has incomparable outstanding advantages in terms of performance, quality, appearance, etc., and enjoys a good reputation in the market.CANWIN summarizes the defects of past products, and continuously improves them. The specifications of Built Cores can be customized according to your needs.
