Induction Heating & Melting Capacitors

4.0kV 600Hz Induction Furnace Water Cooled Capacitor

Designed for high-frequency induction heating applications requiring water-cooled thermal management. Supports metal smelting, heat treatment, forging, welding, and quenching operations.

Product Overview

The RFM series delivers rated voltage of 4.0 kV at 600 Hz, supporting induction furnace applications requiring water-cooled thermal management and high reliability.

The capacitor construction uses metallized polypropylene film dielectric with self-healing properties. Advanced materials and manufacturing processes ensure electrical performance and long-term reliability. The rated working voltage of 4.0 kV enables stable operation under high-voltage conditions, while the 600 Hz high-frequency design effectively reduces inductance loss, improves current transmission efficiency, accelerates heating, and improves overall production efficiency.

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.

Installation & Operation Notes

01

Cooling Water Quality

Use deionized or softened water with conductivity below 10 µS/cm to prevent galvanic corrosion within the cooling channels. Maintain pH between 6.5 and 8.5. Filtration to 50 µm is recommended.

02

Water Flow Requirements

Flow rate depends on specific power rating and ambient conditions. For standard applications, flow rate of 4-6 L/min per 100 kvar is typical, with inlet temperatures between 15°C and 35°C. Detailed cooling requirements provided with each unit.

04

Electrical Connections

Torque bus bar connections to specified values to minimize contact resistance. Loose connections cause localized heating and potential performance degradation. Follow manufacturer specifications.

05

Frequently Asked Questions

What is the recommended water flow rate and inlet temperature for the cooling circuit? +
Flow rate depends on the specific power rating and ambient conditions. For standard applications, a flow rate of 4-6 L/min per 100 kvar is typical, with inlet temperatures between 15°C and 35°C. Detailed cooling requirements are provided with each unit based on the operating parameters.
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 water cooling system improve capacitor performance? +
The advanced water-cooling heat dissipation technology effectively disperses heat generated under high-frequency operation, preventing overheating and extending service life. This reduces maintenance costs and ensures stable performance during continuous operation in demanding induction furnace 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. The water-cooled design contributes to reduced thermal stress and extended service intervals, with regular monitoring of capacitance and dissipation factor recommended to track degradation.
