    Frequently Asked Questions

    Q1. What is the frequency range of an ultra high frequency capacitor?

    These capacitors are designed for high-frequency operations ranging from 30kHz, 40kHz, 50kHz, and up to 300kHz. They are specifically developed to satisfy the demanding requirements of ultra-high frequency induction heating equipment.

    Q2. How does an ultra-high frequency induction machine perform surface quenching?

    It utilizes induction heating technology to generate a targeted eddy-current on the workpiece surface. This raises the surface temperature rapidly to 800-1000 degrees Celsius in just a few seconds, facilitating rapid and precise surface quenching of industrial metal parts.

    Q3. What are the key technical specifications of these capacitors?

    Key technical specifications include a maximum rated voltage of 8K VAC, a rated frequency of up to 300 KHZ, an all-film medium, a water-cooling method for heat dissipation, and the use of degradable, non-PCB insulation oil.

    Q4. How do these capacitors contribute to energy conservation?

    By being integrated into the induction heating and melting process, these capacitors help improve the power factor of the system. A higher power factor optimizes electrical efficiency, which directly reduces overall energy consumption.

    Q5. Why is water-cooling necessary for these capacitors?

    Since the capacitors operate at ultra-high frequencies (up to 300kHz) and high voltages, they generate significant thermal energy. The water-cooling system ensures efficient heat dissipation, maintaining stable performance and extending the product's operational lifespan.
