Product Description

Product Description

Introducing the (H)GWBEB type outdoor high-voltage isolation switch, a state-of-the-art solution also recognized as an isolation disconnect switch. Expertly designed for the demanding needs of 10(12, 15, 24)kV high voltage power transmission and distribution lines, it seamlessly facilitates the opening and closing of single-phase or three-phase circuits. This exceptional switch operates safely with voltage present, yet without load, ensuring reliable performance in critical applications.

Crafted specifically for single-phase deployment within three-phase line systems, this switch boasts a straightforward structure, making it both a cost-effective and user-friendly solution. It is available in an impressive range of rated currents, including 200, 400, 600, 800, 1000, and 1250 amps. The robust construction comprises a durable base, high-quality post insulators, conductive components, and a mechanical section designed for optimal performance. Utilizing an innovative gate knife structure to manage circuit operations, each phase features a dual blade system complemented by external compression springs on both sides. The spring height can be finely adjusted to ensure the necessary contact pressure for the switch's gate knife, providing unmatched precision. The switch is manipulated via a specialized insulated hook stick, featuring a self-locking device that guarantees secure and efficient operation.

Working Environment:

Engineered for altitudes not exceeding 1000 meters,

Capable of withstanding ambient temperatures ranging from a maximum of +40°C to a minimum of -30°C,

Designed to withstand outdoor wind speeds not exceeding 35 meters per second,

Built to endure seismic intensities up to 8 degrees, ensuring stability even without frequent severe vibrations at the installation site.

Ideal for installation sites free from gases, chemical deposits, salt mist, dust, dirt, or any other explosive or corrosive mediums that could significantly impair the switch's insulation and conductivity.

Note:

SHOULD THE NORMAL USE CONDITIONS BE SURPASSED, USERS ARE ENCOURAGED TO ENGAGE IN A DISCUSSION WITH THE COMPANY FOR CUSTOM SOLUTIONS.

 

Installation, Use and Adjustment

Pre-installation work

1. Ensure all parts are free from dust and dirt, meticulously cleaning the surface of the insulating porcelain bottle for optimal performance.
2. Thoroughly scrub the wiring surface of the ground screw to ensure a clean connection.
3. Apply a protective layer of industrial Vaseline to all rotating parts and contact areas to enhance longevity and reliability.
4. Inspect the contact surface and adjust the compression spring height to maintain the contact pressure as specified in Table II, ensuring consistent and reliable operation.
5. This switch is optimally designed for hoisting use, seamlessly integrating with transformers on the line for enhanced efficiency.
6. The switch is rated for currents between 200 to 400 amperes, typically utilizing three mounting holes; configurations for 600-1000A also use three mounting holes for secure installation.

Regular annual checks should be conducted on the following switch components:
Remove any accumulated dirt from conductive parts, contact surfaces, and the insulating porcelain bottles to maintain optimal performance.

Inspect all components for potential damage, with special attention to the insulating porcelain bottle for any signs of damage or cracks.

Ensure the contact surface of the conductive parts remains in excellent condition, facilitating reliable electrical connections.
