(H)GWBEB type outdoor high-voltage isolation switch, also revered as an isolation disconnect switch, is meticulously crafted for deployment on 10(12, 15, 24)kV high voltage power transmission and distribution lines. It operates to seamlessly open and close single-phase or three-phase circuits while maintaining voltage presence, yet without a load. This engineering marvel is a testament to innovation and precision.
This switch, intended for single-phase application within three-phase line systems, is lauded for its uncomplicated design, cost-efficiency, and user-friendly operation. With rated currents spanning 200, 400, 600, 800, 1000, and 1250 amps, it meets diverse power needs. The construction comprises a robust base, post insulators, conductive components, and a finely engineered mechanical section. The innovative gate knife structure facilitates the smooth opening and closing of circuits. Each phase's gate knife includes dual conductive blades, complemented by external compression springs for optimal performance. Spring height adjustments ensure precise contact pressure. The switch is maneuvered with an insulated hook stick, featuring a self-locking device for secure operation.
Working Environment:
Altitude: Not exceeding 1000 meters; ensuring optimal performance even at considerable heights.
Ambient Temperature: Capable of withstanding a maximum of +40°C and a minimum of -30°C, it operates reliably across a broad temperature spectrum.
Outdoor Wind Speed: Withstands wind speeds up to 35 meters/second, ensuring robust reliability in windy conditions.
Seismic Intensity: Resistant to seismic activities up to 8 degrees; installation sites must remain free from frequent severe vibrations, ensuring stability and safety.
Installation Site: Ideal for environments free from gases, chemical deposits, salt mist, dust, dirt, or other explosive or corrosive mediums, ensuring impeccable insulation and conductivity.
Note:
WHEN THE ABOVE NORMAL USE CONDITIONS ARE EXCEEDED, USERS MAY ENGAGE IN DISCUSSIONS WITH THE COMPANY FOR TAILORED SOLUTIONS.
Installation, Use and Adjustment
Pre-installation work
Conduct an annual inspection of the following switch components:
Meticulously remove dirt from conductive parts, contact surfaces, and the insulating porcelain bottle surface to maintain superior conductivity.
Diligently inspect all parts for any damage, with particular focus on the insulating porcelain bottle for any signs of damage or cracks, ensuring structural integrity.
Ensure the conductive part's contact surface remains in excellent condition, guaranteeing uninterrupted power flow.
