PRODUCT OVERVIEW AND WORKING CONDITIONS

◆Electric heating capacitors are mainly used in induction heating systems to improve power factor or improve loop characteristics. The performance of our products meets the requirements of GB/T 3984.1-2004 “Power Capacitors for Induction Heating Devices”.

◆ Indoor installation, the altitude does not exceed 1000m.

◆The installation site has no severe mechanical vibration, no harmful gases and vapors, and explosive dust.

◆The cooling water inlet temperature does not exceed 30 °C. For capacitors below 1000kvar, the water flow rate is not less than 4L/min, and 1000kvar and above is not less than 6L/min.

◆Long-term over-voltage (no more than 4 hours in 24 hours) does not exceed 1.1UN, and long-term overcurrent (including harmonic current) does not exceed 1.35IN.

FEATURES

◆Pressure protection, stable quality and high cost performance.

◆The bushing is conductive or grounded, safer.

◆Environmental protection medium: NO PCB.

◆Full water cold, semi-water cooled.
