[/b] [b]  [/b] A lot of high-frequency transformers will be winding one lap [url=http://www.yft88.com/zztbjd.shtml/][u][color= #00ff] self-adhesive copper foil [/color][/u][/url ], this is to prevent the external high-frequency interference signal into the machine, so in the transformer between the primary and secondary have an electrostatic shielding layer, (a thin layer of copper foil can not be shorted, generally with the steel bracket of the transformer), and connect it to the bottom of the machine. In addition, the existence of the shielding layer greatly reduces the distribution capacitance between the initial secondary coil, which can reduce the transmission of the high frequency spurious interference signal. Because the equivalent capacitance is connected in series, the capacitance between the first stage becomes smaller naturally. and the high-frequency component can be directly vented through the capacitance of the ground.   [url=http://www.yft88.com/article/tbjdzbyqzd_1.html][b][u][color= #00ff] Transformer copper foil and self-adhesive copper foil [/color][/u][/b][ /URL][B] where is it sold? [/b] [b]  [/b] Guangdong Foshan transformer manufacturer Lvcheng, the use of the network to find Suzhou always sensitive, through 20 minutes of technical exchanges, Lu always ordered a batch of always sensitive [url=http://www.yft88.com/products/ zztbfddj.html][u][color= #00ff] Transformer self-adhesive copper foil [/color][/u][/url]. The current product production has been completed, expressed thanks to always sensitive to help him to complete the order, but also said that it will be long-term cooperation with Suzhou always sensitive.
