Product Description

Product Description

(H)GWBEB type outdoor high-voltage isolation switch, also known as the isolation disconnect switch, is a cutting-edge solution meticulously engineered for deployment on 10(12, 15, 24)kV high voltage power transmission and distribution lines. This innovative switch facilitates the seamless opening and closing of single-phase or three-phase circuits under voltage, but without any load, ensuring optimal performance and reliability.

Tailored specifically for single-phase applications within three-phase line systems, this switch boasts a straightforward design, offering both cost-effectiveness and user-friendly operation. With a range of rated currents available, including 200, 400, 600, 800, 1000, and 1250 amps, it affords versatility to meet diverse operational needs. The switch is composed of a sturdy base, durable post insulators, conductive components, and a resilient mechanical section, all working in harmony to ensure efficient functionality. Its gate knife structure, comprising dual conductive blades per phase and externally mounted compression springs on both sides, allows for precise contact pressure adjustments via spring height modification. The switch's operation is streamlined through an insulated hook stick, complemented by a self-locking mechanism for enhanced security and ease of use.

Working Environment:

Altitude requirements: not exceeding 1000 meters; ensuring optimal operational conditions.

Ambient temperature: a comfortable maximum of +40°C to a minimum chill of -30°C;

Outdoor wind speed: maintain a serene environment with speeds below 35 meters/second;

Seismic intensity: limited to a maximum of 8 degrees; ensure installation sites are free from frequent severe vibrations.

Installation sites must be devoid of gases, chemical deposits, salt mist, dust, dirt, or other explosive or corrosive mediums that could impede the switch's insulation and conductivity.

WHEN STANDARD OPERATING CONDITIONS ARE EXCEEDED, USERS ARE ENCOURAGED TO CONSULT AND NEGOTIATE WITH OUR COMPANY.

Installation, Use and Adjustment

Pre-installation work

1. Begin by thoroughly cleaning dust and dirt from all components, ensuring the insulating porcelain bottle surfaces are meticulously wiped down for optimal functioning.
2. Carefully scrub and clean the wiring surface of the ground screw to maintain efficient connectivity.
3. Apply a protective layer of industrial Vaseline to all rotating parts and critical contact areas to enhance longevity and performance.
4. Inspect the contact surfaces and adjust the compression spring height to ensure the contact pressure aligns perfectly with the specifications detailed in Table II.
5. Note that this switch is exclusively designed for hoisting applications, working seamlessly in conjunction with transformers on the line.
6. For currents ranging from 200-400 amperes, the switch typically utilizes three mounting holes, while configurations of 600-1000A also employ three mounting holes.

Annual Maintenance Recommendations: Conduct regular inspections to ensure optimal functionality, focusing on the following areas:
Meticulously clean dirt and contaminants from conductive parts, contact surfaces, and the insulating porcelain bottle's surface to maintain pristine conditions.

Assess all components for any potential damage, with particular attention given to inspecting the insulating porcelain bottle for any signs of damage or cracking.

Verify the integrity of the conductive part's contact surface to ensure continued excellent connectivity.
