Induction Heating & Melting Capacitors

3.0kV 8400kvar 700Hz RAM Induction Heating and Melting Capacitor

Designed for precision material processing requiring high-temperature control. Supports rapid heating and melting of aluminum, copper, steel, stainless steel, and special alloys across casting, heat treatment, and welding pretreatment applications.

Product Overview

The RAM series delivers rated voltage of 3.0 kV with reactive power capacity of 8400 kvar at 700 Hz, supporting high-frequency induction heating and melting applications requiring precision and efficiency.

The capacitor construction uses metallized polypropylene film dielectric with self-healing properties. The 3.0 kV high-voltage design combined with ultra-large capacity of 8400 kvar ensures rapid and accurate energy conversion at 700 Hz high frequency, significantly improving heating efficiency, shortening melting time, and reducing energy consumption costs. The advanced closed-loop temperature control system achieves microsecond-level control by precisely adjusting the frequency and intensity of induced current.

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 closed-loop temperature control system work? +
The advanced closed-loop temperature control system achieves microsecond-level control by precisely adjusting the frequency and intensity of the induced current. This ensures uniform heating with minimal temperature fluctuations, making it suitable for precision material processing that requires extremely high temperature control accuracy.
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 reinforced structural design contribute to extended service intervals, with regular monitoring of capacitance and dissipation factor recommended to track degradation.
What materials can this capacitor support for heating and melting? +
This capacitor is suitable for rapid heating and melting of a variety of metals and alloys, including but not limited to aluminum, copper, steel, stainless steel, and special alloys. The 8400 kvar capacity and precise temperature control enable efficient processing across different material types with varying melting points and thermal properties.
