Dry Type Low-voltage Shunt Capacitor
Dry Type Low-voltage Shunt Capacitor
Product Description
Dry Type Low-voltage Shunt Capacitor's suitable for the power frequency AC power system with rated voltage of 1000v and below, which helps to improve the quality of the power grid, increase the power factor and reduce the line loss.
Dry Type Low-voltage Shunt Capacitor has the advantage of small volume, light weight,low dissipation, low temperature rise, long life, good self-healing and good safety.
