Frequently Asked Questions

What is the difference between live case and isolated case configurations? +

In live case configuration, one terminal is internally connected to the capacitor casing, requiring the casing to be grounded. This design is typically used in systems where the capacitor is part of a grounded circuit. In isolated case configuration, all terminals are isolated from the casing, providing flexibility for floating or ungrounded system designs.

What is the difference between single cooled and double cooled configurations? +

Single cooled configuration uses one cooling system and includes sub-sections for internal fault isolation. Double cooled configuration provides enhanced thermal management with two independent cooling systems and no sub-sections, suitable for higher power applications requiring maximum heat dissipation capacity.

How does the capacitor achieve high energy conversion efficiency? +

Optimized capacitor structure and dielectric formulation enable efficient conversion of electrical energy into thermal energy. This results in rapid and efficient heating, significantly increasing heating speed and shortening production cycles across various industrial applications.

What is the expected service life under continuous operation? +

Service life is influenced by operating temperature, voltage stress, and duty cycle. Under rated conditions with proper cooling, the design life exceeds 80,000 hours. High-quality insulation materials and advanced manufacturing processes contribute to extended service intervals, with regular monitoring of capacitance and dissipation factor recommended to track degradation.
