Detailed Description

Our company has a 30 years experience in manufacturing vacuum capacitors since the former company began in 1970s. We are making about 70 models vacuum capacitors. We have the ability for developing, trial manufacturing and mass-producing. Vacuum capacitors are widely used in: Broadcast communication equipment Vacuum capacitors are used in medium wave, shortwave and ultra shortwave transmitters, act as the tuning, coupling, wave sieving, counteracting component. Plasma deposition and etching equipment for semiconductor manufacturing. High frequency industrial equipment for high frequency heating and brazing. Medical instruments. Medical analysis instruments and treatment instruments High-energy physics. High-energy particle accelerator. Power equipment. Medium waste test equipment. 3.2 Performance of vacuum capacitors Vacuum capacitors have higher withstanding voltage, smaller volume, lower loss and more reliable performance than capacitors with other medium. The particular performance includes the following: Rated voltage-Due to the excellent insulation of vacuum and the dustproof and moistureproof performance, vacuum capacitors have high rated voltage when the dimension and the volume are certain. It can achieve hundreds thousands of voltage. Small loss and high rated current-As vacuum capacitors are made with vacuum medium, low loss ceramic shell and oxygen-free copper plate, it can carry large RF current under general convection cooling, even the frequency is very high. The carrying RF current can achieve thousands of amperes. Save space-to a certain capacitance and rated voltage, vacuum capacitors need smallest space. Wide capacitance range-the ratio of the biggest capacitance to the smallest achieve 150: 1, from several pf to thousands of pf, it is an ideal component for wide range tuning. Self cured ability for excessive voltage-Vacuum capacitor can withstand instantaneous excessive voltage, which will permanently damage other sort of capacitors. Work in high altitude-vacuum airproof allow vacuum capacitor to work in high altitude without performance decrease.
