    The Key to Reliability - Long-Lasting Lightning Protection Performance of Doorhandle Capacitors
    Lightning arresters must remain readily operational for decades. High-voltage doorhandle capacitors achieve exceptionally long lifespans through optimized materials and enhanced processes:

    Dielectric Material: Barium strontium titanate-based ceramic doping suppresses aging effects under electric field strength, resulting in a capacitance change of ≤±5% after 10,000 hours of accelerated aging testing.

    Electrode and Package: Aluminum foil protrusion welding and a lead-free press-fit structure prevent lead edge burrs from damaging the dielectric, enhancing mechanical strength.

    Thermal Management: A low dissipation factor (tanδ ≤ 0.001) combined with heat dissipation from the metal casing keeps the full-load temperature rise to ≤15K. In areas prone to thunderstorms (such as substations in mountainous areas), these capacitors can withstand over 100 surges annually, have a design life of over 20 years, and a failure rate of less than 0.1%, significantly reducing operation and maintenance costs.
