The specifications of Built Cores can be customized according to your needs.

Epoxy resin dry transformer small volume, light weight. Epoxy resin dry transformer is equipped with low noise amplitude-flow fan, which can reduce winding temperature, improve load capacity and prolong transformer life after starting. When forced air cooling is used, the rated capacity can be increased by 40-50%.

10KV intelligent box type switcher is a new generation of load switcher, vacuum breaker and other switch elements, suitable for distribution automation, that is, compact and scalable distribution equipment. It has the advantages of oil-free, multi-combination, maintenance, modular, corrosion resistance, high reliability, strong adaptability to the environment and so on. In and out of the loop according to the requirements of users, you can meet the manual, electric operation, circuit breaker circuit by matching the corresponding intelligent controller and other related equipment.

The inner and outer surfaces of the coil are reinforced by glass fiber mesh cloth.After circuit processing, the temperature of each phase winding is displayed on the control board. It has the function of temperature setting, manual/automatic start and stop of fan, alarm of over temperature sound and light signal and automatic trip of over temperature, etc.

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.

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.

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.
