Transformer shielding cover manufacturers, what are the knowledge of shielding cover +15 years of focus on shielding cover manufacturers

Transformer shield manufacturers, shielding is to isolate the metal between two spatial areas to control the induction and radiation of electric fields, magnetic fields and electromagnetic waves from one area to another. Specifically, shielding is used to surround the interference source of components, circuits, assemblies, cables or the entire system to prevent the interference electromagnetic field from spreading; shielding to surround the receiving circuit, equipment or system to prevent them from being exposed to the outside world. The influence of electromagnetic fields. Because the shielding body absorbs energy (eddy current loss), reflected energy (reflection of electromagnetic waves on the interface of the shielding body) and canceling energy (electrical interference) and internal electromagnetic waves from external interference electromagnetic waves such as wires, cables, components, circuits or systems. Magnetic induction produces a reverse electromagnetic field on the shielding layer, which can offset part of the interference electromagnetic wave), so the shield has the function of reducing interference. (1) When the frequency of the interfering electromagnetic field is high, the eddy current generated in the low-resistivity metal material is used to form the cancellation effect of the external electromagnetic wave, so as to achieve the shielding effect. (2) When the frequency of interfering electromagnetic waves is low, materials with high magnetic permeability should be used, so that the lines of magnetic force are limited to the inside of the shield and prevent spreading to the shielded space. (3) In some cases, if a good shielding effect is required for both high-frequency and low-frequency electromagnetic fields, different metal materials are often used to form a multi-layer shielding body. Hardware, focusing on transformer shield manufacturers for 15 years, focusing on the quality of shielding covers, starting from the design of the mold, and doing every tiny movement and process, the flatness is controlled within 0.07mm in the process. There are 16 quality inspections, and the quality is strictly checked. With a daily production capacity of 3 million strokes, every customer is satisfied with quality, service, and production capacity!
