The transformer is a device for changing the voltage according to the principle of electromagnetic induction. The core is the magnetic circuit therein, which plays the role of the electric energy conversion medium. The output voltage of the transformer can be increased by the cooperation of the core and the winding turns. High or low; at the same time, the core can also be used as a transformer skeleton, set windings, support leads, wood clamps, tap-changers and other components, which are indispensable in the transformer.
The E-core, also called ED-core, designed and manufactured by Nicore, can be widely used in transformer field because of its open structure of three-phase and two-and-a-half assembling and its characteristics of various sizes. It has advantages that other common stamping cores do not have.
The material of E-core is cold-rolled oriented high-quality silicon steel with low iron loss and high magnetic conductivity. Through highly advanced winding equipment and high vacuum annealing process, the E-core is cut into the required specifications by precision cutting instruments. The whole process of production is very efficient, and can ensure the high-quality magnetism of the core. Because the open structure of closed magnetic circuit can be formed by assembling, the transformer with E-core can make coils separately from iron core in production, and then cover coils on iron core, which can shorten the production period and improve production efficiency.
NICORE equipped with highly advanced and automated equipment, has a strong production capacity. It can produce cutting E-core for various purposes according to customer's requirements. In addition to being used in transformer field, inductors and reactors are also used, so that customers can rest assured.
