Functional Use
The NWC5 series self-healing low voltage shunt capacitor is suitable for AC power systems with a rated voltage of 1000V and below, to improve the power factor, reduce reactive power loss, and improve voltage quality. This type of product is the mainstream product in countries such as Europe and the United States. The filling medium of the product is rapeseed oil, which has the best heat dissipation performance.
