High-voltage Porcelain Dielectric Cylindrical Capacitor

Our High-voltage Porcelain Dielectric cylindrical Capacitor is prepared with high-purity porcelain dielectric material, which is a highly reliable capacitor product designed exclusively for harsh working conditions and outdoor high-voltage scenarios. Porcelain dielectric has extremely strong insulation performance, weather resistance and anti-fouling ability. Compared with ordinary ceramic dielectric, it has less insulation attenuation and longer service life under harsh environments such as high temperature and high humidity, dust and oil pollution, and outdoor exposure, and can stably adapt to the long-term operation needs of outdoor high-voltage equipment. Relying on the factory's 17 years of R&D and production experience in high-voltage porcelain dielectric, this High-voltage Porcelain Dielectric cylindrical Capacitor has optimized the dielectric formula and sintering process, with lower dielectric loss and stronger voltage shock resistance. At present, it has been supplied in batches to customers in the fields of outdoor high-voltage power supplies and power grid testing equipment, and is also exported to South Asia, the Middle East and other regions with complex climatic environments.

This High-voltage Porcelain Dielectric cylindrical Capacitor adopts an axially symmetrical cylindrical structure with uniform electric field distribution. It supports multiple series combinations and can flexibly build high-voltage modules of different voltage levels. The product covers multiple voltage and capacitance specifications, supports various lead-out methods such as bolt terminals and axial leads, and can be customized in size and parameters according to customers' installation needs. The whole production process is controlled by automated procedures, and the whole process from porcelain material preparation to finished product packaging is completed independently. Quality inspection nodes are set in each process, combined with 100% full inspection before delivery to ensure stable and reliable product performance. We have sufficient large-scale production capacity and can quickly respond to customers' batch order needs. It is a preferred highly reliable product for overseas agents to expand outdoor industrial and power customers.

It is widely used in outdoor high-voltage power supplies, outdoor power grid testing equipment, outdoor units of electrostatic dust removal, outdoor units of high-voltage voltage dividers, vehicle-mounted high-voltage devices, field testing equipment, industrial equipment in high temperature and high humidity environments and other scenarios, especially suitable for high-voltage working conditions with complex environmental conditions and high requirements for dielectric weather resistance and insulation stability, undertaking core circuit functions such as filtering, voltage division, coupling and energy storage.

We strictly control the whole production process of High-voltage Porcelain Dielectric cylindrical Capacitors in accordance with the ISO9001:2015 quality management system. In view of the outdoor application characteristics of porcelain dielectric cylindrical capacitors, special reliability test links such as humidity and heat cycle resistance and temperature shock are added. All finished products undergo 100% full inspection before delivery, covering core electrical indicators such as withstand voltage performance, capacitance accuracy, dielectric loss and insulation resistance. Samples pass environmental reliability verification to ensure that the products can adapt to long-term operation under complex working conditions. We have a dedicated quality inspection team, and each process is set with special personnel for verification to prevent unqualified products from flowing into the next link and ensure the quality stability of delivered products.

We have dedicated after-sales contact personnel to provide full-cycle service support for customers of porcelain dielectric cylindrical capacitors. Before sales, we can provide professional selection suggestions and adaptation schemes according to customers' use environment and working condition needs; during sales, we can simultaneously update pictures or videos of production progress, so that customers can grasp order dynamics in real time; after sales, all products enjoy a 2-year warranty period (except for man-made damage and force majeure factors). If the goods are damaged due to non-force majeure during transportation, we provide free replacement service. If customers encounter any technical problems during use, we will respond quickly and provide targeted solutions.

We have passed the ISO9001:2015 quality management system certification. The whole production process of High-voltage Porcelain Dielectric cylindrical Capacitors is strictly implemented in accordance with the system standards, with standardized and perfect quality control. The whole production process of the factory complies with domestic environmental protection regulations, and the porcelain dielectric materials and production processes meet relevant environmental protection standards. The products can adapt to the market access requirements of most regions in the world. All products are delivered with formal test reports, and complete qualification documents can be provided for customer verification. We support customers to designate third-party institutions to conduct on-site inspection, providing comprehensive support for overseas market expansion and compliant procurement.
