Product Description

Product Description

(H)GWBEB type outdoor high-voltage isolation switch, also recognized as an isolation disconnect switch, is expertly crafted for deployment on 10(12, 15, 24)kV high voltage power transmission and distribution lines. Its primary function is to adeptly open and close single-phase or three-phase circuits without load, yet with voltage present, ensuring seamless operations.

This high-efficiency switch is purpose-built for single-phase utilization in three-phase line systems, boasting a straightforward design that ensures both cost-efficiency and user-friendliness. Offered in a range of rated currents, including 200, 400, 600, 800, 1000, and 1250 amps, these switches are composed of a sturdy base, dependable post insulators, robust conductive components, and a mechanical section. The innovative gate knife structure ensures reliable circuit opening and closing. Each phase's gate knife is ingeniously crafted with two conductive blades, complemented by external compression springs on both sides. By adjusting the spring height, optimal contact pressure for the switch's gate knife is achieved. The switch operation is facilitated through an insulated hook stick for seamless opening and closing actions, all while featuring a secure self-locking device.

Working Environment:

Altitude: should not exceed 1000 meters; ensuring optimal performance.

Ambient temperature: maintaining a maximum of +40°C and a minimum of -30°C, suitable for various climatic conditions.

Outdoor wind speed: must not exceed 35 meters/second, ensuring stability and safety.

Seismic intensity: should not surpass 8 degrees; the installation site must be free from frequent intense vibrations to guarantee security.

The installation location must be clear of gases, chemical deposits, salt mist, dust, dirt, and any other explosive or corrosive mediums that severely compromise the switch's insulation and conductivity.

Note:

WHEN THE ABOVE NORMAL USE CONDITIONS ARE EXCEEDED, USERS ARE ENCOURAGED TO CONSULT WITH THE COMPANY TO EXPLORE VIABLE SOLUTIONS.

Installation, Use and Adjustment

Pre-installation work

1. Thoroughly remove any dust and dirt from the components, and meticulously clean the surface of the insulating porcelain bottle to maintain its integrity.
2. Scrub the wiring surface of the ground screw to ensure excellent connectivity.
3. Apply a generous layer of industrial Vaseline to the rotating parts and contact areas to promote smooth operation.
4. Inspect the contact surface and adjust the compression spring's height to ensure the contact pressure adheres to Table II's specifications.
5. This switch is exclusively designed for hoisting and is intended to be used in conjunction with the transformer on the line, offering efficient integration.
6. The rated current for this switch ranges from 200-400 amperes, with three mounting holes generally used. For 600-1000A, three mounting holes are consistently employed to ensure secure installation.

Essential annual maintenance includes regular inspection of the following components of the switch:
Meticulously remove dirt from conductive parts, contact surfaces, and the insulating porcelain bottles' surface to maintain optimal functionality.

Examine all parts for potential damage, with particular attention to inspecting the insulating porcelain bottle for any signs of damage or cracks.

Verify that the contact surface of the conductive part remains in excellent condition for reliable performance.
