Product Description

Product Description

The (H)GWBEB type outdoor high-voltage isolation switch, an exceptional isolation disconnect switch, is expertly crafted for deployment on 10(12,15,24)kV high voltage power transmission and distribution lines. This innovative switch is engineered to facilitate the seamless opening and closing of single-phase or three-phase circuits under the presence of voltage, but without load. Its advanced design ensures reliable performance across a spectrum of high voltage environments.

Tailored exclusively for single-phase applications within three-phase line systems, this switch stands out for its minimalistic yet robust architecture. It offers a delightful blend of cost-effectiveness, simplicity, and user-friendliness. The switch comes in a variety of rated currents: 200, 400, 600, 800, 1000, and 1250 amps, accommodating diverse operational needs. It incorporates a base, post insulators, conductive parts, and a mechanical section, all harmonized to deliver peak performance. The ingenious gate knife structure seamlessly facilitates the circuit's opening and closing, with each phase utilizing dual conductive blades complemented by external compression springs. These springs' heights are adjustable to attain the requisite contact pressure for the gate knife. Operated effortlessly with an insulated hook stick, the switch also features a self-locking device for enhanced security.

Working Environment:

Operate at altitudes not exceeding 1000 meters for optimal performance;

Maintain ambient temperatures within a maximum of +40°C and a minimum of -30°C;

Ensure outdoor wind speeds do not surpass 35 meters/second;

Installations should remain robust against seismic intensity levels not exceeding 8 degrees, and should avoid locations prone to frequent severe vibrations.

Select installation sites free from gases, chemical deposits, salt mist, dust, dirt, or any other explosive or corrosive mediums that could severely compromise the switch’s insulation and conductivity.

Note:

SHOULD THE ABOVE NORMAL USE CONDITIONS BE SURPASSED, USERS ARE ENCOURAGED TO DISCUSS CUSTOM SOLUTIONS WITH THE COMPANY.

Installation, Use and Adjustment

Pre-installation work

1. Carefully eliminate any dust and dirt from parts, and meticulously clean the surface of the insulating porcelain bottle.
2. Thoroughly scrub the wiring surface of the ground screw to ensure optimal conductivity.
3. Coat the rotating parts and contact areas with a protective layer of industrial Vaseline to enhance performance.
4. Inspect the contact surface and fine-tune the compression spring's height to ensure the contact pressure meets the specifications outlined in Table II.
5. This switch is uniquely designed for hoisting applications, perfectly complementing transformers along the line.
6. The switch, rated for currents between 200-400 ampere hours, typically requires three mounting holes, with the 600-1000A variants also utilizing three holes for secure installation.

Conduct a thorough yearly inspection of the following switch components:
Meticulously remove any dirt from conductive parts, contact surfaces, and insulating porcelain bottle surfaces.

Examine all components closely for damage, with particular attention to the insulating porcelain bottle for any signs of damage or cracks.

Assess if the contact surface of the conductive part remains in excellent condition.
