Product Description

Product Description

The (H)GWBEB type outdoor high-voltage isolation switch, also revered as an isolation disconnect switch, is the pinnacle of engineering for 10(12, 15, 24)kV high voltage power transmission and distribution lines. It masterfully opens and closes single-phase or three-phase circuits, maintaining voltage presence without the burden of load.

Crafted for single-phase usage within three-phase line systems, this switch boasts an uncomplicated structure, unparalleled cost-effectiveness, and user-friendly operation. With an array of rated currents—200, 400, 600, 800, 1000, and 1250 amps—this versatile switch is constructed with a robust base, resilient post insulators, premium conductive parts, and an efficient mechanical section. Its innovative gate knife structure facilitates seamless circuit opening and closing, featuring dual conductive blades with strategically placed external compression springs. By modifying the spring height, users can fine-tune the contact pressure of the gate knife. An insulated hook stick ensures safe and efficient operation, complemented by a reliable self-locking device.

Working Environment:

Altitude: Not to exceed 1000 meters;

Temperature Range: Maximum +40°C; Minimum -30°C;

Wind Conditions: Outdoor wind speed should not surpass 35 meters/second;

Seismic Conditions: Seismic intensity should remain below 8 degrees; the site must be free from frequent severe vibrations.

Site Conditions: Avoid sites with gases, chemical deposits, salt mist, dust, dirt, or any explosive or corrosive elements that could impair the switch's insulation and conductivity.

Note:

Should the aforementioned normal use conditions be exceeded, the user is encouraged to engage in a consultation with the company.

Installation, Use and Adjustment

Pre-installation Work

1. Ensure the removal of dust and dirt from all components, meticulously cleaning the insulating porcelain bottle's surface.
2. Thoroughly scrub the wiring surfaces of the ground screw.
3. Apply a generous layer of industrial Vaseline to all rotating parts and contact areas to ensure smooth operation.
4. Inspect the contact surfaces and adjust the compression spring height to meet the specifications outlined in Table II.
5. This switch is designed exclusively for hoisting use and should be used in conjunction with the transformer on the line for optimal performance.
6. The switch's rated current spans from 200 to 400 ampere hours, with three mounting holes typically utilized. For ratings of 600-1000A, three mounting holes are standard.

Annual Inspection Checklist:
Conduct a thorough removal of dirt from conductive parts, contact surfaces, and the insulating porcelain bottles.

Examine all components for potential damage, with a particular focus on identifying any damage or cracks in the insulating porcelain bottle.

Assess the contact surface of the conductive parts for optimal connectivity.
