Surge Absorbing Capacitors
Unparalleled Surge Protection with Yuhchang Surge Absorbing Capacitors

Yuhchang’s surge absorbing capacitors are designed to provide superior surge protection for high-voltage motors, transformers, and generators. These capacitors are engineered to absorb and mitigate voltage surges that can occur during breaker operations or from lightning strikes. By connecting between line and ground, Yuhchang capacitors effectively protect essential equipment from damaging voltage spikes, enhancing operational reliability and longevity.

Why Yuhchang Surge Absorbing Capacitors?

Yuhchang surge absorbing capacitors are built to the highest standards, including JEM 1362 and IEC 60871, ensuring global compatibility and performance. They are certified under ISO 9001:2015, demonstrating Yuhchang's commitment to quality. These capacitors are suitable for both indoor and outdoor use up to an altitude of 1000 meters above sea level. They operate efficiently at frequencies of 50/60Hz, and can withstand varying ambient temperatures ranging from -20℃ to +50℃

Key specifications include a dissipation factor of less than 0.5%, insulation resistance above 1000MΩ, and a maximum permissible current of 135% of the rated current. The capacitors are sealed to prevent oil leakage even under high temperatures, ensuring maintenance-free operation.

Constructed using high-grade polypropylene film as the dielectric and filled with non-PCB insulation fluid, Yuhchang capacitors are durable and environmentally friendly. The use of stainless steel for the case material, coupled with epoxy and urethane paint systems, provides excellent resistance to corrosion, acids, alkalis, and weather conditions. The wet process porcelain bushing, colored in Munsell 5B 8/4, adds to its aesthetic and functional appeal.

Surge Absorbing Capacitors for Critical Voltage Protection

Yuhchang surge absorbing capacitors are ideal for diverse applications where voltage surge protection is critical. They are extensively used in industrial setups to safeguard transformers, high-voltage motors, and generators. Additionally, they can be deployed in various sectors including energy, manufacturing, and any domain that utilizes complex electrical machinery requiring reliable voltage regulation.

By choosing Yuhchang surge absorbing capacitors, businesses ensure the protection of their valuable assets against unexpected voltage surges, minimizing downtime and maximizing productivity. Contact us for further info!
