Product Description

Product Description

(H)GWBEB type outdoor high-voltage isolation switch, often referred to as an isolation disconnect switch, is meticulously crafted for operation on 10(12, 15, 24)kV high voltage power transmission and distribution lines. It masterfully opens and closes single-phase or three-phase circuits without a load, yet with voltage present.

Engineered for single-phase use within three-phase line systems, this switch is renowned for its straightforward design, economic viability, and user-friendly nature. With rated currents available at 200, 400, 600, 800, 1000, and 1250 amps, these switches are expertly composed of a base, post insulators, conductive components, and a mechanical section. Utilizing a gate knife structure to facilitate opening and closing the circuits, each phase's gate knife features two conductive blades complemented by external compression springs on both sides. By adjusting the spring height, the essential contact pressure for the gate knife is achieved. Operation is seamlessly conducted using an insulated hook stick for opening and closing actions, and it includes a robust self-locking device.

Working Environment:

Altitude should not exceed 1000 meters;

Ambient temperature: must not surpass a maximum of +40°C, nor drop below a minimum of -30°C;

Outdoor wind velocity should not exceed 35 meters/second;

Seismic intensity shall remain below 8 degrees; the installation site must be free from frequent severe vibrations.

The site of installation must remain clear of gases, chemical deposits, salt mist, dust, dirt, or any other explosive or corrosive substances that could severely impact the switch's insulation and conductivity.

Note:

WHEN CONDITIONS EXCEED THE ABOVE NORMAL USE PARAMETERS, CUSTOMERS SHOULD ENGAGE IN DISCUSSIONS WITH THE COMPANY FOR FURTHER ASSISTANCE.

Installation, Use and Adjustment

Pre-installation Procedures

1. Ensure removal of dust and dirt from components, with careful attention to wiping the surface of the insulating porcelain bottle.
2. Clean the wiring surface of the ground screw thoroughly.
3. Apply a generous layer of industrial Vaseline to all rotating parts and contact areas to ensure smooth operation.
4. Verify the contact surface and adjust the compression spring height to ensure the contact pressure aligns with Table II specifications.
5. This switch is specifically designed for hoisting use and is intended for seamless operation in conjunction with line transformers.
6. With a rated current spanning 200-400 ampere hours, it typically requires only three mounting holes, while 600-1000A setups utilize three mounting holes for enhanced stability.

Annual Maintenance Checklist:
Ensure the removal of dirt from all conductive parts, contact surfaces, and the insulating porcelain bottle surfaces.

Inspect all components for potential damage, particularly focusing on checking the insulating porcelain bottle for any cracks or fractures.

Assess whether the contact surface of the conductive part remains in optimal condition.
