HV Porcelain-based Cylindrical Capacitor

Our HV Porcelain-based cylindrical Capacitor adopts a porcelain-based composite substrate and an integrated cylindrical structure design. It is an industrial-grade high-voltage capacitor product that balances high electrical performance and high mechanical strength. While ensuring excellent insulation and withstand voltage performance, the porcelain-based substrate has stronger mechanical strength and anti-vibration ability. It can withstand continuous vibration and installation torque during the operation of industrial equipment, is not prone to ceramic body hidden cracks and performance attenuation, and is very suitable for application scenarios with vibration loads such as built-in industrial high-voltage equipment and vehicle-mounted high-voltage devices. Relying on the factory's years of accumulation in porcelain-based material R&D and molding technology, this HV Porcelain-based cylindrical Capacitor has realized the balanced optimization of electrical performance and mechanical performance. At present, it has been supplied in batches to customers in the fields of industrial high-voltage generators and mobile testing equipment, and has been widely recognized by the market.

This HV Porcelain-based cylindrical Capacitor covers multiple voltage and capacitance specifications, adopts standardized cylindrical size design, can directly replace conventional ceramic capacitors of the same specification, and also supports customized non-standard products with special sizes and parameters to adapt to the assembly needs of different equipment. The terminal electrode of the product adopts a high-strength bonding process, which has strong bonding force with the porcelain-based substrate, is not easy to fall off under long-term vibration working conditions, and has stable contact resistance. The whole production process adopts automated molding and high-temperature sintering processes, with quality inspection nodes set throughout the whole process, and 100% full inspection before delivery to ensure that the electrical performance and mechanical strength of each product meet the standards. We have stable large-scale supply capacity, short delivery cycle of standard products, and can quickly respond to customers' batch replenishment needs. It is a cost-effective supporting choice for overseas industrial customers.

It is mainly used in industrial high-voltage generators, mobile X-ray testing equipment, vehicle-mounted high-voltage devices, industrial electrostatic equipment, high-voltage power supply modules, high-voltage equipment under vibration working conditions, portable high-voltage instruments and other scenarios, especially suitable for industrial high-voltage environments with continuous vibration and installation stress requirements, undertaking core circuit functions such as energy storage, filtering, voltage boosting and coupling.

We support OEM/ODM customization services for HV Porcelain-based cylindrical Capacitors. Customers can provide technical drawings, samples or specific parameter requirements. The customization content covers multiple dimensions such as porcelain-based size, voltage and capacitance grade, lead-out method and plating material, and can be specially optimized for special vibration working conditions and installation space. The development cycle of customized samples is 25 days, supporting small-batch trial production verification to ensure that the product adapts to customers' equipment needs. The minimum order quantity for conventional products is 100 pieces, and mixed purchases of products of different models are supported within a single MOQ order, meeting the needs of agents for multi-category stock preparation and small-batch trial procurement by terminal customers.

We support FOB trade terms. For conventional standard HV Porcelain-based cylindrical Capacitors, the payment method is 30% advance payment and 70% balance paid before delivery; for customized 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 issue corresponding settlement bills according to customer needs. For bulk purchase orders and long-term cooperative agent customers, we provide tiered price discounts. The larger the order volume, the stronger the preferential intensity, ensuring the profit space of cooperative partners. All cooperation shall sign a formal purchase and sales contract to clarify the delivery cycle and quality standards, ensuring standardized and orderly cooperation.
