HV Circular Porcelain Capacitor

Our HV Circular Porcelain Capacitor adopts an integrated circular ceramic body structure design, which is the classic structural capacitor category most widely used in medium and high voltage equipment. The structural characteristics of the circular ceramic body make the internal electric field distribution of the product more uniform. Compared with special-shaped structural capacitors, it has a higher withstand voltage margin under the same volume, and at the same time has a larger heat dissipation area, lower temperature rise under long-term high-voltage working conditions, and stronger operation stability. Relying on the factory's mature dry pressing molding and high-temperature sintering processes, the ceramic body of this HV Circular Porcelain Capacitor has uniform density, no internal bubbles and delamination defects, high mechanical strength, can withstand conventional installation torque and working condition vibration, and is suitable for built-in installation requirements of various industrial equipment.

This HV Circular Porcelain Capacitor covers a wide voltage range from 3kV to 150kV, with complete capacitance specifications, and can adapt to various installation methods such as bolt type and lead type to meet the assembly needs of different equipment. The ceramic body of the product is made of high-purity high-voltage ceramic raw materials, sintered at one time at a high temperature above 1200℃, and the terminal electrode adopts silver-copper composite plating with strong bonding force and low contact resistance, with excellent thermal shock resistance and anti-aging performance. Under normal working conditions, its service life far exceeds the industry average. We can customize circular ceramic capacitor products of corresponding sizes and performances according to customers' equipment installation space and parameter requirements, supporting small-batch customization and large-batch mass production. It is a core supporting component for power equipment and environmental protection equipment manufacturers, and also a main procurement category for overseas purchasers.

It is widely used in medium and high voltage equipment such as high-voltage electrostatic dust removal equipment, tar electrostatic trapping devices, industrial high-voltage power supplies, high-voltage voltage dividers, voltage transformers, Marx pulse generators, electron accelerators, X-ray medical equipment and non-destructive testing equipment, especially suitable for high-voltage circuit scenarios with high requirements for heat dissipation performance, electric field uniformity and mechanical strength.
