Cylindrical Self-healing Low Voltage Shunt Capacitor

Cylindrical Self-healing Low Voltage Shunt Capacitor

The DZ/C cylindrical series capacitors are packaged in cylindrical aluminum shells and are suitable for low voltage power systems with a frequency of 50/60Hz. They are made of advanced edge thickened zinc aluminum composite metalized polypropylene film and wound into shape in a constant temperature and humidity environment; At the same time as injecting the dielectric material, inert nitrogen gas is injected in a vacuum environment for dual protection, ensuring excellent reliability and oxidation resistance of the capacitor components; Mainly used for improving power factor, reducing reactive power loss, and enhancing the quality of low-voltage power grids.
