Self-healing Low Voltage Shunt Capacitor

In the core technology system of Self-healing Low Voltage Shunt Capacitors, the electrode coating ratio of the metallized film is regarded as the genetic code that determines the reliability of the product. The combination of zinc and aluminum metals at the nanoscale thickness is not a simple physical mixture; instead, it is constructed through precise atomic arrangement to form a functional interface that can intelligently respond to electrical stress impacts. The research and technical team of Ge Yue Electric, through continuous research for over a decade, finally uncovered the balance art in this microscopic world.

During the self-healing process, the zinc and aluminum elements in the metallized film of the Self-healing Low Voltage Shunt Capacitors play distinct yet complementary key roles. The aluminum element, with its lower melting point and excellent ductility, can quickly form a liquid film when heated at the breakdown point. This fluidity ensures that the faulty area can be completely cleared, creating the prerequisite conditions for insulation reconstruction. The zinc element, with its higher boiling point and stable chemical properties, plays an anchoring role during the self-healing process, preventing the metal spatter range from expanding indefinitely and causing extensive damage to the capacitor. When the ratio of zinc to aluminum reaches the optimal level, the rapid response of aluminum and the stable restraint of zinc form a perfect complement, allowing the self-healing process to both maintain sufficient energy to complete the dielectric cleaning and not damage the long-term lifespan of the capacitor due to excessive reaction.

The slight deviation in the ratio of aluminum and zinc elements in the coating of Self-healing Low Voltage Shunt Capacitors will directly lead to significant differences in the self-healing effect. When the aluminum content exceeds the ideal range, excessive fluidity will cause the self-healing area to be much larger than actually needed. Each self-healing action will lose too much electrode material, resulting in accelerated capacity decay of the capacitor. Conversely, if the zinc proportion is too high, the metal coating is difficult to fully vaporize at the breakdown point, and the remaining conductive particles may form new weak areas, significantly increasing the probability of repeated breakdown. More seriously, the mismatched metal content ratio will generate microscopic stresses on the metalized film surface. These stress concentration points will become the preferred locations for future breakdown, significantly reducing the expected service life of the self-healing capacitors.

Thanks to our industry-leading magnetron sputtering technology, Geyue Electric can precisely control the ratio of zinc and aluminum elements in the metallized film of Self-healing Low Voltage Shunt Capacitors at the atomic level. Our proprietary technology can stabilize the zinc-aluminum ratio within the optimal range, ensuring that every square meter of metallized film has an average and consistent self-healing property. This precise control stems not only from advanced production equipment but also from our well-established testing system. Throughout our production chain, each batch of raw materials must undergo simulated self-healing experiments. Our research and technical teams reverse-optimized the zinc-aluminum content formula by analyzing the success rate of thousands of capacitor self-healing actions and the data on capacitor capacity attenuation. Our BSMJ(Y) series Self-healing Low Voltage Shunt Capacitors are the scientific outcome of this continuous reverse optimization. Their unique zinc-aluminum metal proportion safeguards a self-healing success rate of over 99.97% and limits the capacity loss during a single self-healing to less than 0.05%.

Geyue Electric firmly believes that the outstanding low-voltage reactive power compensation equipment is attributed to the manufacturers' meticulous pursuit and in-depth control of every technical detail. The Geyue Electric BSMJ(Y) series three-phase Self-healing Low Voltage Shunt Capacitors have found an optimal coupling point between self-healing efficiency and electrode durability through a highly optimized zinc-aluminum coating ratio.
