Withstand Voltage Testing The company is equipped with a professional film withstand voltage testing platform to verify dielectric strength under high-voltage conditions. Metallization Layer Performance Testing Using imported German metallizing equipment, the company ensures stable and uniform metallization layers. Key inspections include coating resistance consistency, self-healing capability, conductivity stability, edge insulation performance, and thermal stability.

Film Capacitor Testing Capacitance & Electrical Parameter Testing All products undergo automated electrical performance testing, including capacitance tolerance, dissipation factor, frequency stability, and voltage performance. Insulation & Withstand Voltage Testing The company uses high-precision automatic dielectric strength testers for insulation resistance testing, leakage current testing, and high-voltage withstand verification to ensure electrical safety performance. High-Temperature Testing Through constant-temperature high-temperature chambers, capacitors undergo continuous high-temperature operation testing, temperature rise monitoring, post-aging stability evaluation, and thermal shock resistance testing.

Environmental Testing System Salt Spray Testing

Verifies the corrosion resistance of product housings and terminals in humid and coastal environments.

Glow Wire Testing Evaluates flame-retardant and safety performance under abnormal high-temperature conditions. Damp Heat Aging Testing Verifies long-term operational stability and insulation reliability under high-humidity environments.
