Product Description

Product Description

(H)GWBEB type outdoor high-voltage isolation switch, also referred to as an isolation disconnect switch, is expertly crafted for deployment on 10(12, 15, 24)kV high voltage power transmission and distribution lines. It is specifically designed to facilitate the opening and closing of single-phase or three-phase circuits, without carrying a load but with voltage still present.

Purpose-built for single-phase operations within three-phase line systems, this switch stands out due to its straightforward design, exceptional cost efficiency, and user-friendly attributes. It is available in rated currents of 200, 400, 600, 800, 1000, and 1250 amps. The construction consists of a robust base, post insulators, conductive components, and a precise mechanical section. Incorporating a gate knife mechanism, each phase's gate knife utilizes two conductive blades with external compression springs on either side. By adjusting the spring height, the ideal contact pressure for the switch's gate knife is achieved. Operated with an insulated hook stick for seamless opening and closing, the switch also features a reliable self-locking device.

Working Environment:

Altitude should not exceed 1000 meters;

Ambient temperature: maximum not exceeding +40°C; minimum not dropping below -30°C;

Outdoor wind speed: must not exceed 35 meters/second;

Seismic intensity should not surpass 8 degrees; the installation site must be free from frequent severe vibrations.

The installation location must be devoid of gases, chemical deposits, salt mist, dust, dirt, or any explosive or corrosive substances that could seriously impair the switch's insulation and conductivity.

Note:

SHOULD THE ABOVE STANDARD USAGE CONDITIONS BE EXCEEDED, USERS ARE ENCOURAGED TO ENGAGE IN DISCUSSIONS WITH THE COMPANY.

Installation, Use, and Adjustment

Preparation Before Installation

1. Thoroughly clean dust and debris from the components, ensuring to gently wipe the insulating porcelain bottle's surface.
2. Carefully scrub the wiring surface of the ground screw.
3. Apply a protective layer of industrial Vaseline to all rotating parts and contact surfaces.
4. Inspect the contact surfaces and adjust the compression spring height to ensure it conforms to the specified contact pressure in Table II.
5. Designed exclusively for hoisting applications, this switch operates in tandem with transformers on the power line.
6. The switch's rated current ranges from 200 to 400 ampere hours, typically utilizing three mounting holes. For 600-1000A, three mounting holes are used.

Annually inspect the following components of the switch:
Thoroughly clean any dirt from conductive parts, contact surfaces, and the insulating porcelain bottles' surface.

Inspect all components for any signs of damage, with particular attention to potential harm and cracks in the insulating porcelain bottle.

Verify that the contact surfaces of the conductive parts remain in optimal condition.
