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.

High and low voltage winding according to the requirements of heat dissipation is provided with a longitudinal ventilation airway.

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.

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.

Overview of intelligent high-speed silicon steel sheet shearing line(1)     The equipment adopts a central positioning system and is equipped with two shears and five punches:(2)     One 45º shearing machine and one 135º shearing machine;(3)     Two V punching and shearing machines use servo motor control systems to move forward and backward and left and right;(4)     Three punching machines use linear motor control systems to move left and right;(5)     Three punching machines, V punching and shearing machines and one direct shear can cut simultaneously.(6)     The equipment is a high-speed shearing model, regardless of punching or not, the shearing speed of the 1-meter-long piece (side piece + yoke piece; side piece + side piece) can reach more than 80 pieces/min; The cutting speed reaches 60 pieces/min.(7)     Adopt back-suction neat material sorting system, which can realize neat or step-by-step material sorting.

YBM (P) series box transformer substation (hereinafter referred to as box transformer) is a compact complete set of power distribution equipment composed of high-voltage power equipment, power transformer, low-voltage electrical equipment and auxiliary equipment.

Slitting line equipment mainly includes the following:Loading trolley, double support uncoiler, feeding device, traction leveling machine, trimming shearing machine, deviation correction feeding device, longitudinal shear line, waste edge winder, feed rack, pre separation device, tensioner, feeding roller, winding shearing machine, steering drum, rear axle, discharge trolley, winding auxiliary support, hydraulic system and electrical system, etc.The materials that can be processed by longitudinal shear equipment include cold-rolled plate, stainless steel plate, aluminum plate, galvanized plate and color coated plate. However, for different materials, there are certain differences in the strength of blade materials, so as to obtain good cutting effect.

Three-dimensional wound core transformer breaks through the traditional triangle plane structure, adopts three-phase symmetric vertical structure, magnetic circuit completely symmetrical three-phase core products, magnetic resistance is greatly reduced, excitation current, no-load loss, is a kind of using traditional materials, but lower operating noise, structure is more compact and efficient energy-saving transformers. Its excellent performance in energy saving and energy saving and environmental protection is in line with China's energy conservation policy.
