High-voltage Ceramic Round Plate Capacitor

Our High-voltage Ceramic Round Plate Capacitor adopts a flat round plate integrated structure design, which is the core basic component in high-voltage measurement and pulse circuits. The round plate-shaped ceramic body has uniform surface electric field distribution and low edge electric field distortion. Compared with conventional cylindrical capacitors, it has lower partial discharge and stronger capacitance stability under the same voltage level, which is very suitable for high-voltage measurement scenarios with high requirements for accuracy and anti-interference. Relying on 17 years of accumulation of ceramic dielectric molding technology in the factory, this High-voltage Ceramic Round Plate Capacitor is prepared by isostatic dry pressing molding process, with high ceramic body density and uniform dielectric constant. The capacitance deviation of the whole batch of products is strictly controlled, which can meet the supporting requirements of high-precision equipment such as high-voltage voltage dividers and metering sensors. At present, it has served domestic power grid metering and testing equipment manufacturers in batches, and is exported to Russia, India and other overseas markets.

This High-voltage Ceramic Round Plate Capacitor supports full-size customization, and the ceramic body diameter, thickness, electrode plating form and lead-out method can be adjusted according to customers' installation space and electrical parameter requirements. The whole production process is controlled by automated procedures. From ceramic material batching, pressing molding to high-temperature sintering and electrode plating, each process is set with parameter verification nodes, combined with 100% full inspection before delivery, to ensure that the withstand voltage level, capacitance accuracy and insulation performance of each product meet the standards. Whether it is batch standardized supporting for equipment manufacturers or special specification customization for scientific research projects, we can provide stable supply support and technical cooperation, and it is the core selected product for overseas agents to expand industrial measurement customers.

It is widely used in high-voltage voltage dividers, high-voltage power grid metering sensors, voltage transformers, Marx pulse generators, electrostatic dust removal high-voltage power supplies, high-voltage detection and calibration equipment, scientific research experimental high-voltage devices, X-ray machine high-voltage modules and other scenarios, especially suitable for high-voltage measurement and pulse circuits with strict requirements on capacitance accuracy and partial discharge indicators, undertaking core circuit functions such as voltage division, coupling and pulse energy storage.

We support full-process OEM/ODM customization services for High-voltage Ceramic Round Plate Capacitors. Customers can provide technical drawings, samples or specific parameter requirements, and our R&D team will quickly complete scheme evaluation and sample development. The customization content covers multiple dimensions such as ceramic body diameter, thickness, capacitance accuracy grade, electrode plating material and lead-out structure, and the development cycle of customized samples is 25 days. The minimum order quantity for conventional products is 100 pieces, and mixed purchases of products of different specifications are supported within a single MOQ order, fully meeting the needs of agents for multi-category stock preparation and small-batch trial production by terminal customers.

We strictly control the whole production process in accordance with the ISO9001:2015 quality management system. In view of the characteristics of round plate capacitors, a special partial discharge detection link is added. All finished products undergo 100% full inspection before delivery, covering core indicators such as withstand voltage strength, capacitance accuracy, dielectric loss, insulation resistance and partial discharge. We are equipped with 2 sets of DC ultra-high voltage testing equipment and special partial discharge detection devices to ensure that each product meets the parameter standards. We support customers to designate third-party institutions to conduct on-site inspection, and fully cooperate with all testing and verification to ensure delivery quality.

In view of the fragile and bump-resistant characteristics of the round plate ceramic body, we adopt a layered protective export packaging scheme. The inner packaging uses high-density EPE foam to wrap each product independently, and then puts it into a custom card slot for fixation to avoid friction and collision during transportation; the outer packaging adopts thickened five-layer corrugated cartons with hard paper corner protectors installed at the edges and corners. The whole package has good moisture-proof, compression-resistant and impact-resistant capabilities, and can be adapted to various international transportation methods such as sea freight, land transportation and air transportation. We support FOB trade terms, can cooperate with the freight forwarder designated by the customer to arrange shipment, and attach a complete test report and packing documents with the goods to ensure smooth customs clearance.
