27KV 82.5PF High Voltage Ceramic Capacitor Sand Blasted Electrodes Equipped High Performance
Features
- Superior Sand - Blasting Advantage: Our high - voltage ceramic capacitor features a sand - blasted surface with Rz≥40um. This treatment thoroughly cleans the surface, removing impurities and creating a sleek, uniform appearance. It also enhances heat dissipation. The increased surface area from sand - blasting allows heat to dissipate more efficiently, maintaining a stable operating temperature and extending the capacitor's lifespan. Additionally, it improves the adhesion of coatings, ensuring that protective layers and markings stay intact.
- Well - Engineered Electrodes: The capacitor is equipped with electrodes at both ends that have been carefully processed to remove sharp edges and corners. This not only enhances safety during operation but also minimizes the risk of electrical discharge and improves electrical performance stability. The electrodes are made of high - quality materials, ensuring excellent electrical conductivity even under high - voltage conditions.
- Excellent Dielectric Properties: Utilizing advanced ceramic materials as the dielectric, this capacitor offers outstanding dielectric performance. The ceramic dielectric has a high dielectric constant, enabling it to store a large amount of electrical energy in a relatively small volume. This results in a compact yet highly efficient capacitor. It also has low dielectric loss, reducing energy consumption during operation and improving overall system efficiency.
Applications
- live line indicators
- AC dividers
- Grading systems for power distribution network
- Protection for HV switches and power circuit breakers

The company has total assets of 315 million RMB Yuan, fixed assets of 137 million RMB Yuan, which is a large enterprise mainly engaged in producing electronic components. The company has the largest production scale of Varistor,SPD( Surge Protective Device)and HV Ceramic Capacitor in China, with the following main products :
1. Varistors & SPD
2. HV Ceramic Capacitor
3. Capacitive Voltage Divider
4. Thermistor
The main production line and inspection equipment & instrument are imported from Japan, America, Belgium and Switzerland etc. The annual production capacity of the two leading products has been reached to 5 million pcs and 150 million pcs respectively, with the market holding rate in China of about 10% and 30% respectively by continually technical innovation. Varistors and SPD produced by the company enjoyed great reputation in the international market, being exported to many countries and areas such as Japan,USA, Hong Kong etc., with the customers like India and GE in USA. are already sold to LG company in Korea with large quantity, and also to Spainand India etc.
Not only the products quality and technical capacity, but also the completeness of the models are all in the leading place in China. The main products have got CCEE, UL, VDE & TUV approval. The quality system was set up according to the requirement of ISO9000 since 1992, and has passed ISO9002 approval by DNV International Organization in July 1994, then got ISO9001 certification by British organization in 2000, by then we are both the first one who are approved by ISO9000 certification in the North-west area of China and the same occupation. We passed all the successive periodical audit and smoothly get the new certificate registered in Holland in Aug.1997; the quality system is strengthened and completed constantly. And we also got ISO18000 certificate.
We believe we are able to supply satisfied goods and service to customers home and abroad with the most reasonable price and the shortest delivery time, on basis of our excellent quality assurance capacity, technical development capacity and rich manufacturing experiences.
