DC smoothing reactors string in the DC circuit reduces current ripple, when the inductor reaches a certain amount of energy to ensure the continuous flow of current, especially for DC power generated when drying, it will cause the motor terminal voltage and speed suddenly l, and not conducive to the motor commutation. Therefore, the rectifier circuit to be in series smoothing reactors. The product is a dry-type reactor core. Using high quality imported cold core low-loss oriented silicon steel, the gap with epoxy glass cloth laminated board for the interval to ensure that the reactor gap does not change during operation. Class F coil magnet wire wound, a relatively low temperature and the heat generated is also relatively small, less impact on the surrounding electrical components. Reactor dipping reduces overall noise runtime. The reactor has a small size, light weight, beautiful appearance and so on. The main production and sales of reactors, transformers, resistors, stainless steel resistors, frequency sensitive rheostat, resistance cabinet, linkage thirteen categories more than sixty series on thousands of products units, braking resistance. Our products are widely used in metallurgy, electric power, coal, construction machinery, chemical and other medium-sized industrial projects, covering more than 20 industries. Company sales in major cities across the country, and China Metallurgical Design Institute, gold from Tengen other major automation companies, too, Benxi Iron and Steel, Laiwu Steel, Jinan Iron and Steel, Wuhan Iron and Steel nine, Handan Iron and Steel, big play, Tianjin Pipe Group, the country more than 200 well-known medium-sized enterprises to establish a long-term relationship, and as a designated supplier for key projects supporting. Products have been exported to Japan, America, Southeast Asia and other countries. www.sddqel.com responsible for collating
