Product Description

Product Description

The (H)GWBEB type outdoor high-voltage isolation switch, also known as an isolation disconnect switch, is expertly engineered for deployment on 10(12, 15, 24)kV high voltage power transmission and distribution lines. It facilitates the effortless opening and closing of single-phase or three-phase circuits under voltage without load, ensuring seamless energy management.

Designed with simplicity and efficiency in mind, this switch is intended for single-phase utilization within three-phase line systems. Its hallmark features include a straightforward structure, cost-effectiveness, and user-friendly operation. Choose from a range of rated currents: 200, 400, 600, 800, 1000, and 1250 amps. Constructed with a robust base, steadfast post insulators, conductive components, and a mechanical section, these switches employ a gate knife mechanism for circuit operations. Each phase incorporates a double-blade gate knife, complete with external compression springs to optimize contact pressure through adjustable spring height. The switch operation is controlled using an insulated hook stick for secure opening and closing, complemented by a self-locking device for added safety.

Working Environment:

The installation altitude must not exceed 1000 meters;

The ambient temperature should range between a maximum of +40°C and a minimum of -30°C.

The outdoor wind speed must not surpass 35 meters/second;

Seismic resilience is ensured up to an intensity of 8 degrees; ensure the installation site is free from frequent severe vibrations.

The installation site must be devoid of gases, chemical residues, salt mist, dust, dirt, and other explosive or corrosive elements that could significantly impair the switch's insulation and conductivity.

Note:

IN CASE OF OPERATING BEYOND THESE NORMAL CONDITIONS, USERS ARE ENCOURAGED TO CONSULT WITH THE COMPANY FOR CUSTOM SOLUTIONS.

Installation, Use and Adjustment

Pre-installation work:

1. Ensure all parts are free from dust and dirt, and meticulously clean the surface of the insulating porcelain bottle for optimal performance.
2. Thoroughly scrub the wiring surface of the ground screw to maintain connectivity.
3. Apply a protective layer of industrial Vaseline to rotating parts and contact surfaces for smooth operation.
4. Inspect the contact surface and adjust the compression spring height to ensure the contact pressure aligns with the standards set in Table II.
5. This switch is uniquely designed for hoisting applications and should be used in conjunction with a transformer on the line for comprehensive energy management.
6. For rated currents of 200-400 amperes, usually three mounting holes are used, while for currents of 600-1000A, three mounting holes are also standard.

Conduct an annual inspection of the following switch components:
Regularly eliminate dirt from conductive parts, contact surfaces, and the insulating porcelain bottle's exterior to ensure optimal operation.

Thoroughly examine all components for any signs of damage, with particular attention to the insulating porcelain bottle for integrity and absence of cracks.

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