Product Description

Product Description

Introducing the (H)GWBEB type outdoor high-voltage isolation switch, a premier solution in the realm of electrical power systems. Known in the industry as an isolation disconnect switch, this innovative device is meticulously engineered for seamless operations on 10(12, 15, 24)kV high voltage power transmission and distribution lines. Its primary function is to skillfully open and close single-phase or three-phase circuits, even in the presence of voltage, without any load. Elevate your power grid's reliability with this state-of-the-art switch.

Designed with precision for single-phase applications in three-phase line systems, our switch stands out with its straightforward design, affordability, and user-friendly nature. It accommodates a range of rated currents: 200, 400, 600, 800, 1000, and 1250 amps. The robust construction comprises a sturdy base, resilient post insulators, conductive components, and a sophisticated mechanical section. Utilizing a gate knife structure, it ensures efficient circuit operations. Each phase features a gate knife with dual conductive blades, supported by external compression springs that are adjustable for optimal contact pressure. Operate with ease using an insulated hook stick, and benefit from its built-in self-locking mechanism, ensuring secure and reliable performance at all times.

Working Environment:

Ensure optimal performance with an altitude not exceeding 1000 meters.

Maintain ambient temperature conditions: maximum of +40°C and minimum of -30°C.

Operates efficiently in outdoor conditions with wind speeds not exceeding 35 meters/second.

Designed to withstand seismic intensities up to 8 degrees, ensuring stability in various installations. The site should remain free from frequent severe vibrations.

Installation sites must be free from gases, chemical deposits, salt mist, dust, dirt, or other explosive or corrosive substances that could significantly compromise the switch's insulation and conductivity.

Note:

FOR CONDITIONS OUTSIDE THE SPECIFIED NORMAL USE PARAMETERS, USERS ARE ENCOURAGED TO DISCUSS OPTIONS WITH OUR COMPANY.

 

Installation, Use and Adjustment

Pre-installation work

1. Thoroughly cleanse the switch parts of any dust and dirt, and gently polish the insulating porcelain bottle's surface to ensure pristine condition.
2. Carefully scrub the ground screw's wiring surface for optimal connectivity.
3. Apply a protective layer of industrial Vaseline to all rotating components and contact areas for enhanced performance.
4. Inspect the contact surface meticulously, adjusting the compression spring height to ensure contact pressure aligns with the standards outlined in Table II.
5. This switch is exclusively designed for hoisting applications, to be used in synergy with transformers along the line.
6. For rated currents of 200-400 amperes, three mounting holes are generally utilized. For 600-1000A, three mounting holes are also employed, ensuring secure installation.

Conduct an annual inspection of the switch's components to ensure consistent performance:
Meticulously remove any dirt from conductive parts, contact surfaces, and the insulating porcelain bottles' exteriors.

Examine all components carefully for any signs of damage, with particular focus on detecting any injuries or cracks on the insulating porcelain bottle.

Verify the integrity of the conductive part's contact surface to maintain optimal functionality.
