Ceramic capacitor (ceramic capacitor);Ceramic condenser) is also known as porcelain capacitor or monolithic capacitors.As the name implies, ceramic dielectric vessel is a ceramic capacitor with dielectric material.According to different ceramic materials, this kind of capacitor can be divided into low-frequency porcelain dielectric vessel with capacity of 1-300 pF and high-frequency porcelain dielectric vessel with capacity of 300-22 000 pF.According to the structure type classification, can be divided into picture capacitor, tubular capacitor, rectangular capacitor, chip capacitor, piercing capacitor and so on.

It is understood that high-density thyristors, which are highly technologically intensive and difficult to manufacture, are the “heart†components of the “smart grid†constructed with ultra-high voltage and ultra-high voltage transmission lines. They have long been subject to foreign technology monopolies in the past.
Zhuzhou CSR Times Electric Co., Ltd., a subsidiary of CSR Zhuzhou Co., Ltd., mastered the design, manufacture, and inspection of high-voltage high-power thyristors through independent innovation. It also spent RMB 100 million to build a high-voltage, high-power thyristor industrial base. In one fell swoop, it obtained orders for high-power thyristors from Ningdong DC Project.
660 kV DC Transmission System Mounted "China Heart"
The CSR Zhuzhou Electric Locomotive Research Institute of China announced on November 30 that the Ningdong-Shandong HVDC transmission project has successfully installed a domestic 5-inch 7200 volt thyristor and was officially put into commercial operation, marking that China’s “smart grid†autonomous core equipment manufacturing technology has reached A new height.
