Introducing the (H)GWBEB type outdoor high-voltage isolation switch, a pivotal component in the realm of electrical power management. Known as an isolation disconnect switch, this product is engineered to perfection for 10(12, 15, 24)kV high voltage power transmission and distribution lines. Its primary function is to efficiently open and close single-phase or three-phase circuits that are under voltage. This switch offers a seamless solution for managing high voltage needs with precision and safety, without the burden of load.
Specifically crafted for single-phase use in three-phase line systems, the switch boasts a simple yet highly effective structure. Highly affordable and easy to operate, it comes with rated currents of 200, 400, 600, 800, 1000, and 1250 amps. Composed of a robust base, durable post insulators, premium conductive parts, and a precision-engineered mechanical section, it features a gate knife mechanism for circuit operations. Each phase's gate knife includes two conductive blades with external compression springs on both sides, ensuring optimal contact pressure through adjustable spring height. Operable via an insulated hook stick, this switch also includes a reliable self-locking device for safety and ease.
Working Environment:
The switch is engineered to function at altitudes up to 1000 meters;
Designed to withstand ambient temperatures ranging from a brisk -30°C to a warm +40°C;
Can endure outdoor wind speeds of up to 35 meters/second;
Capable of withstanding seismic activities with intensities up to 8 degrees; the installation site must be free from frequent severe vibrations.
The installation environment must be devoid of gases, chemical deposits, salt mist, dust, dirt, or other explosive or corrosive elements that could compromise the switch's insulation and conductive properties.
Note:
IN CASE OF EXCEEDING THESE SPECIFIED CONDITIONS, USERS ARE ENCOURAGED TO DISCUSS ADAPTIVE SOLUTIONS WITH THE COMPANY.

Annual Maintenance Checklist:
Diligently remove any accumulated dirt from conductive parts, contact surfaces, and the surface of insulating porcelain bottles to maintain functionality.
Conduct a thorough inspection of all components to visually confirm the absence of damage, especially focusing on the insulating porcelain bottle for any cracks or imperfections.
Ensure that the contact surface of the conductive part remains in pristine condition.
