Product Description


Product Name: Low voltage 3 phase capacitor bank power factor correction electrical equipment

Thyristor Switched Capacitor system is designed for 0.4kV low voltage distribution network.It main includes the Thyristor Switches, Capacitors and Reactors, using as a new generation of compensation module with functions of energy saving, reduction of line loss, power factor enhancement and improvement of power quality.
Thyristor Switch
LBT series dynamic switching unit refers to a kind of contactless rapid switch with high reliability, and it is used in dynamic power factor compensation equipment. It is especially applicable to switching occasions requiring rapid and no-wear switching. It is usually applied into occasions where reactive change is frequent,such as lifting equipment, elevator and electric welding
