High Voltage Disconnector

When the high voltage disconnector is opened, there is insulation distance meeting the specified requirements and obvious disconnection sign between the contacts. When it is closed, it can withstand the current in the circuit under normal conditions and the current for a specified time under abnormal conditions, such as short circuit.

    1. GW4 High Voltage DisconnectorComposed of the base, insulators, and the conductive parts, our product includes three monopoles and each monopole has a Π type double-column structure. Each monopole contains two post insulators. The two insulators are respectively mounted on the bearing seats at the two ends of the base, and they are connected by cross connecting rod. The conductive knife switch has left and right contacts
    1. GW5 High Voltage DisconnectorThe activated operating mechanism drives one post insulator to rotate by 90° and the other insulator rotates by 90° in the opposite direction at the same time due to the meshing between the bevel gears. Hence, the left and right contacts are opened or closed to the same side.
    1. GW6A High Voltage DisconnectorThe isolation switch is composed of the base, post insulator, operating insulator, main switch, and the static contact of main switch. The post insulator and operating insulator are mounted on the base and the main switch is mounted on top of the insulators. The static contact of main switch is mounted on the overhead busbar.
    1. GW7F High Voltage DisconnectorThe GW7F high voltage AC isolation switch includes three monopoles and each monopole has a three-pole structure. The disconnect switch is composed of the base, post insulator, main switch, and the main switch static contact.
    1. GW22A High Voltage DisconnectorOur high voltage disconnector mainly consists of the base, post insulator, rotating insulator, main switch, and the static contact of the main switch. The post insulator and rotating insulator are mounted on the base. The main switch is mounted on top of the insulators and the static contact is mounted on the transmission bus.
    1. GW23A High Voltage DisconnectorThe post insulator is mounted on the base and the static contact is mounted on the post insulator.
      The main switch has a single are folding structure. When opening, it is pulled down and a clearly noticeable horizontal insulation fracture is formed with the static contact in the horizontal direction.
    1. Transformer Neutral Point Protection DeviceThe BTK-126kV/252kV transformer neutral point protection device mainly comprises the neutral point disconnector, discharge gap protector, zinc oxide lightning arrester, and current transformer. It plays a protective role when there is lightning overvoltage, operation overvoltage and temporary overvoltage in the transformer neutral point.
