Introducing the (H)GWBEB type Outdoor High-Voltage Isolation Switch, an exceptional isolation disconnect switch crafted for seamless operation on 10(12, 15, 24)kV high voltage power transmission and distribution lines. This switch expertly enables you to open and close single-phase or three-phase circuits without a load, even with voltage present, ensuring superior control and safety.
This switch is meticulously engineered for single-phase application within three-phase line systems, boasting a design that epitomizes simplicity, cost-effectiveness, and user-friendliness. Choose from a range of rated currents-200, 400, 600, 800, 1000, and 1250 amps-tailored to meet your specific needs. Constructed with a robust base, reliable post insulators, durable conductive parts, and a precise mechanical section, the switch features an innovative gate knife structure for efficient circuit operations. Each phase incorporates a gate knife with dual conductive blades and external compression springs on either side, allowing for easy adjustment of spring height to achieve optimal contact pressure. Effortlessly operate the switch using an insulated hook stick for secure opening and closing, complemented by a self-locking device for added stability.
Working Environment:
Operate with confidence at altitudes not exceeding 1000 meters;
Maintain ideal conditions with ambient temperatures ranging from a maximum of +40°C to a minimum of -30°C;
Engineered to withstand outdoor wind speeds of up to 35 meters/second;
Resilient against seismic activities with seismic intensity not exceeding 8 degrees; ensure your installation site is free from frequent severe vibrations for optimal performance.
Choose installation sites free from gases, chemical deposits, salt mist, dust, dirt, or other explosive or corrosive substances that could compromise the switch's exceptional insulation and conductivity.
Note:
WHEN OPERATING BEYOND THE SPECIFIED NORMAL CONDITIONS, USERS ARE ENCOURAGED TO CONSULT WITH THE COMPANY FOR CUSTOM SOLUTIONS.
Installation, Use and Adjustment
Pre-installation Work
Commit to excellence by conducting annual checks on the following switch components:
Meticulously remove all dirt from conductive parts, contact surfaces, and the insulating porcelain bottle's surface to maintain high performance.
Inspect each component for potential damage, with particular focus on identifying any damage or cracks in the insulating porcelain bottle.
Verify the integrity of the contact surface of the conductive part to ensure flawless performance.
