High voltage ceramic capacitors are made of ceramic dielectric. The main features of high voltage ceramic capacitors is excellent withstand voltage. voltage from 3.6KV, 6.5KV, 7.2KV, 10KV, 12KV, 13KV, 15KV, 20KV, 24KV, 25KV, 30KV, 35KV, 36KV, 40KV, 50KV, 60KV, 70KV, 80KV, 100KV, 120KV, 150KV, etc. Used for various AC and DC high voltage circuit applications.
Common types of class 1 ceramic materials are: NPO, C0G, UJ, SL, N4700, etc. The temperature coefficient of these type is quite good. There is a linear relationship of temperature and capacitance. Frequency characteristics and voltage characteristics are also very good, but because the dielectric constant is small, it not suitable to make large capacitance capacitors.
The common types of class 2 ceramic materials are: Y5R, Y5P, Y5T, Y5S, Y5U, Y5V, etc. The temperature coefficient of these ceramic material is non-linear, and the capacity can be quite large, However, the frequency and temperature are not constant.
AnXon high voltage ceramic capacitors can be customized according to special requirements, take internal parallel or series design to achieve high voltage, large capacity, high operating frequency, high withstand impulse voltage, ultra low partial discharge requirements and other requirements can meet the different needs of customers.
The Cylindrical ultra high voltage ceramic capacitors of the AnXon CT8G series have been widely used in power transmission and distribution system power equipment and pulse energy processing equipment such as: power compensation, current limiting, filtering, metering, energy storage and distribution. The particularity of the power system: AC high voltage, high frequency, in the outdoor environment (-40°C to +60°C), lightning strike, high current, etc. In harsh environments, the capacitor is required to have super stability, ie The rate of change is small; at the same time, the measurement, the voltage, etc., require high precision, which places extremely severe demands on the partial discharge of high voltage ceramic capacitors under such circumstances. AnXon high voltage ceramic capacitors have excellent charge and discharge performance, high withstand voltage, good frequency characteristics, can withstand high impulse voltage, ultra low partial discharge characteristics, and AC and DC applications for customers to choose.
