The BSMJ series self-healing low-voltage parallel capacitors are suitable for power frequency AC power systems with a rated voltage of 1000V and below, used to improve power factor and voltage quality.
BSMJ series self-healing low voltage shunt capacitors are designed for industrial frequency AC power systems with rated voltage not exceeding 1000V and are widely used in various power equipment and industrial facilities. The main function of these capacitors is to improve the power factor and voltage quality of the power system, thereby effectively reducing energy consumption and power loss.
By connecting in parallel in the power system, BSMJ series capacitors can compensate for the reactive power caused by inductive loads and improve the overall efficiency of the power system. In addition, these capacitors use self-healing technology, which can automatically repair in the event of a local fault, thereby improving the reliability and service life of the equipment.
In modern power systems, a good power factor not only helps reduce electricity bills, but also reduces pressure on the power grid and improves the operating stability of power equipment. Therefore, the BSMJ series self-healing low-voltage shunt capacitor plays an important role in the optimization and energy saving of power systems, and has become an ideal choice for power engineers and equipment managers.
