WLDG2 series DC isolating switches are mainly used for the main circuits of DC traction power supply systems such as industrial and mining, subways, trolleybuses and other DC traction power supply systems with rated voltages DC2000V and below and rated currents of 6300A and below. They can also be applied to DC power supply systems of other industrial equipment to realize effective electrical isolation of electrical circuits and form obvious disconnection points to ensure the safety of maintenance personnel and equipment.
