HV Disc-shaped Ceramic Capacitor

Our HV Disc-shaped Ceramic Capacitor adopts a large-diameter disc-type integrated ceramic body structure, which is the core key component in ultra-high voltage measurement and pulse power systems. The disc-shaped structure has a larger effective electrode area and more uniform surface electric field distribution. Compared with conventional small-size capacitors, it can achieve higher withstand voltage level and larger capacitance output under the same thickness, and at the same time has smaller edge electric field distortion and lower partial discharge level, which is very suitable for high-precision and high-voltage level equipment scenarios such as ultra-high voltage voltage dividers and Marx pulse generators. Relying on the ultra-high voltage ceramic dielectric technology achievements jointly tackled with Tsinghua University, Tianjin University and other universities since 2016, our HV Disc-shaped Ceramic Capacitor has broken through the industry problems of easy deformation and internal defects of large-size ceramic bodies during sintering, and the product consistency and reliability have been greatly improved. At present, it has been matched with many domestic scientific research institutes and high-voltage testing equipment enterprises, and is also exported to Russia, the European Union and other overseas high-end markets.

This HV Disc-shaped Ceramic Capacitor covers an ultra-wide voltage range from 10kV to 300kV, supports customization of ceramic body specifications with different diameters and thicknesses, and can adapt to various assembly forms such as plane electrodes and central bolt lead-out to meet the structural design needs of different equipment. The whole production process adopts isostatic pressing molding and segmented temperature-controlled sintering process. The whole process from ceramic powder formula preparation to finished product testing is completed independently. It is equipped with a special large-size ceramic body testing station to ensure that the internal compactness, withstand voltage level and capacitance accuracy of each product meet the standards. We have sufficient production capacity for large-size capacitors, can stably undertake batch orders and customized project needs, can not only provide supporting solutions for terminal equipment manufacturers, but also provide high-value-added high-end product category support for overseas agents, helping customers expand the high-end high-voltage component market.

It is mainly used in ultra-high voltage scenarios such as ultra-high voltage voltage dividers, high-voltage metering and calibration devices, Marx pulse power generators, electron accelerators, large electrostatic dust removal high-voltage power supplies, scientific research experimental high-voltage platforms, X-ray machine high-voltage modules and lightning impact testing equipment, especially suitable for high-precision high-voltage measurement and pulse power systems with strict requirements on partial discharge indicators and electric field uniformity, undertaking core functions such as voltage division, coupling and pulse energy storage.

We support full-parameter customization services for HV Disc-shaped Ceramic Capacitors. Customers can provide technical drawings or parameter requirements. The customization content covers multiple dimensions such as ceramic body diameter, thickness, withstand voltage level, capacitance accuracy, electrode form and lead-out structure, which can adapt to non-standard installation and performance requirements under special working conditions. The R&D team will optimize the ceramic material formula and structural design according to the customer's application scenario. The development cycle of customized samples is 25 days, supporting small-batch trial production verification. After the verification is passed, it can be seamlessly connected to large-scale mass production. 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 to meet customers' needs for multi-category testing and stock preparation.

In view of the characteristics of large-size disc-shaped capacitors, we have established an exclusive quality control process. In addition to the full-process quality inspection requirements of the ISO9001:2015 quality management system, three exclusive processes are additionally added: internal injury detection of large-size ceramic bodies, end face flatness detection and special partial discharge test. 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 special ultra-high voltage testing equipment and high-precision testing instruments to ensure that each product meets the use requirements of ultra-high voltage scenarios. We support on-site inspection by third-party institutions and fully cooperate with all testing and verification.

We support FOB trade terms. For conventional standard HV Disc-shaped Ceramic Capacitors, the payment method is 30% advance payment and 70% balance paid before delivery; for customized non-standard products, the payment method is 50% advance payment and 50% balance paid before delivery. We support settlement in both US dollars and RMB, and can provide corresponding settlement documents according to customer needs. For bulk purchases and long-term cooperative agent customers, we provide a tiered price discount policy. The higher the purchase volume, the greater the preferential intensity, fully ensuring the profit space of cooperative partners. All cooperation shall sign a formal purchase and sales contract to clarify rights, responsibilities and delivery standards.
