Square Self-healing Low Voltage Shunt Capacitor

Square Self-healing Low Voltage Shunt Capacitor

The DZ-square series self-healing low-voltage shunt capacitors 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. This capacitor mainly used for improving power factor, reducing reactive power loss, and enhancing the quality of low-voltage power grids.
