(H)GWBEB type outdoor high-voltage isolation switch, often referred to as an isolation disconnect switch, is expertly engineered for 10(12, 15, 24)kV high voltage power transmission and distribution lines. Its purpose is to skillfully open and close single-phase or three-phase circuits without any load, while voltage is still present.
Tailored for single-phase utilization in three-phase line systems, this switch stands out with its straightforward structure, economic efficiency, and user-friendly operation. It comes in diverse rated currents such as 200, 400, 600, 800, 1000, and 1250 amps. The switch is composed of a base, post insulators, conductive components, and a meticulously designed mechanical section. The circuit is alternated using a gate knife structure; each phase features a gate knife with two conductive blades, and it is equipped with external compression springs on each side. By adjusting the spring height, the necessary contact pressure for the gate knife is achieved. The switch operation employs an insulated hook stick for both opening and closing tasks and is reinforced with a self-locking device for enhanced safety.
Working Environment:
Altitude limitation: should not exceed 1000 meters;
Ambient temperature: should not rise above +40°C or fall below -30°C;
Maximum outdoor wind speed: must not surpass 35 meters/second;
Seismic intensity: should not exceed 8 degrees; the installation site must be free from regular severe vibrations.
The installation area must be clear of gases, chemical deposits, salt mist, dust, dirt, or any other explosive or corrosive agents that could severely compromise the switch's insulation and conduction properties.
Note:
WHEN STANDARD USAGE CONDITIONS EXCEED THE LIMITS, USERS ARE ENCOURAGED TO DISCUSS OPTIONS WITH THE COMPANY.
Installation, Use and Adjustment
Pre-installation work
Perform an annual check-up of these switch components:
Thoroughly clean dirt from conductive components, contact surfaces, and the insulating porcelain bottle surface, ensuring optimal functionality.
Inspect all components meticulously for damage, with special emphasis on verifying the insulating porcelain bottle for any signs of damage or cracks.
Ensure the contact surfaces of conductive parts remain in excellent condition to maintain reliable operation.
