Product Description

Product Description

(H)GWBEB type outdoor high-voltage isolation switch, renowned as an isolation disconnect switch, is expertly crafted for deployment on 10(12, 15, 24)kV high-voltage power transmission and distribution lines. It's designed to facilitate the opening and closing of single-phase or three-phase circuits without load, yet with voltage present, ensuring seamless operation.

This switch is engineered for single-phase use within three-phase line systems, boasting a straightforward design, cost-efficiency, and user-friendliness. The available rated currents are 200, 400, 600, 800, 1000, and 1250 amps. It comprises a robust base, durable post insulators, efficient conductive parts, and a mechanical section. Utilizing a gate knife structure for circuit operations, each phase's gate knife features two conductive blades with exterior compression springs on either side. By adjusting the spring height, optimal contact pressure is achieved. The switch is actuated with an insulated hook stick for opening and closing, equipped with a reliable self-locking device.

Working Environment:

Designed for altitudes not exceeding 1000 meters.

Operates efficiently with an ambient temperature ranging from a maximum of +40°C to a minimum of -30°C.

Capable of withstanding outdoor wind speeds up to 35 meters/second.

Rated for seismic intensities not surpassing 8 degrees, ensuring stability in areas without frequent severe vibrations.

The installation site must be free from gases, chemical deposits, salt mist, dust, dirt, and other explosive or corrosive substances that could impair the switch's insulation and conductivity.

Note:

IF THE ABOVE NORMAL USAGE CONDITIONS ARE EXCEEDED, USERS ARE ENCOURAGED TO CONSULT WITH THE COMPANY.

Installation, Use and Adjustment

Pre-installation work

1. Thoroughly clean dust and dirt from all parts, and gently polish the surface of the insulating porcelain bottle for optimal performance.
2. Meticulously scrub the wiring surface of the ground screw to ensure seamless connectivity.
3. Coat the rotating parts and contact areas with a generous layer of industrial Vaseline to maintain smooth operation.
4. Examine the contact surface and adjust the compression spring height to ensure the contact pressure aligns with Table II standards.
5. Optimally designed for hoisting use, this switch functions in conjunction with the transformer on the line.
6. The switch accommodates rated currents of 200-400 ampere hours, with three mounting holes generally utilized. For 600-1000A, three mounting holes are also employed.

Conduct annual inspections to maintain the switch's integrity:
Regularly clean dirt from conductive parts, contact surfaces, and the surface of insulating porcelain bottles to ensure continued efficiency.

Inspect all components for damage, with particular focus on the insulating porcelain bottle to identify any cracks or damage.

Verify that the contact surface of the conductive parts remains in excellent condition.
