3.3kV 500Hz Power Capacitor Induction Heating Capacitor

Designed for efficient, stable, and long-lasting induction heating applications. Widely used in metal smelting, heat treatment, welding, and semiconductor manufacturing industries.

Product Overview

The RFM series delivers rated voltage of 3.3 kV at 500 Hz, supporting induction heating applications requiring high-frequency response and stable energy output.

The capacitor construction uses metallized polypropylene film dielectric with self-healing properties. Special insulating materials and optimized design structure ensure long-term stable operation in 3.3 kV high-voltage environments, effectively resisting voltage fluctuations and ensuring system safety. The 500 Hz high-frequency design provides frequency response characteristics, enabling rapid response and stable energy output, improving heating efficiency and shortening the heating cycle.

Three configuration options are available to accommodate different system requirements: single cooled-live case design with sub-sections (one terminal connected to casing), single cooled-isolated case design with sub-sections (all terminals isolated), and double cooled-isolated case design without sub-sections (all terminals isolated). This flexibility allows integration with various system grounding requirements and thermal management approaches.

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 ensure safety in high-voltage environments? +

The capacitor uses special insulating materials and optimized design structure to ensure long-term stable operation in 3.3 kV high-voltage environments. Built-in multiple safety protection mechanisms including overvoltage protection, overcurrent protection, and temperature monitoring ensure safe operation under demanding working conditions.

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. Special insulating materials contribute to extended service intervals, with regular monitoring of capacitance and dissipation factor recommended to track degradation.

What industries benefit from this capacitor? +

This capacitor is widely used in high-end industrial fields including metal smelting, heat treatment, welding, and semiconductor manufacturing. Its efficient, stable, and durable design makes it suitable for demanding industrial applications requiring reliable power delivery and precise control.
