Product Description

Product Description

Introducing the (H)GWBEB type outdoor high-voltage isolation switch, an indispensable asset known as the isolation disconnect switch. Crafted for unparalleled performance on 10(12, 15, 24)kV high voltage power transmission and distribution lines, this switch excels at opening and closing single-phase or three-phase circuits in the presence of voltage, effortlessly and safely.

Tailored for single-phase operations within three-phase line systems, this switch stands out for its streamlined design, economic advantage, and user-friendly operation. Available in rated currents of 200, 400, 600, 800, 1000, and 1250 amps, it is composed of a robust base, durable post insulators, high-quality conductive parts, and a precise mechanical section. Featuring an innovative gate knife structure, each phase's gate knife incorporates two conductive blades, fortified by external compression springs on both sides, ensuring optimal contact pressure through adjustable spring height. The switch is manually operated with an insulated hook stick for seamless opening and closing actions, enhanced by a reliable self-locking device.

Working Environment:

Operates efficiently at altitudes up to 1000 meters, guaranteeing robust performance.

Withstands ambient temperatures ranging from a sweltering +40°C to a chilly -30°C, ensuring reliability in diverse climatic conditions.

Resilient against outdoor wind speeds up to 35 meters/second, providing secure and stable operation.

Structured to endure seismic intensities up to 8 degrees, this switch is ideal for locations with minimal severe vibrations.

Optimal performance is ensured when the installation site is free from gases, chemical deposits, salt mist, dust, dirt, and other explosive or corrosive mediums that could compromise insulation and conductivity.

Installation, Use and Adjustment

Pre-installation work

1. Thoroughly cleanse all parts to remove any dust and dirt, ensuring a spotless surface on the insulating porcelain bottle.
2. Meticulously scrub the wiring surface of the ground screw to ensure optimal connectivity.
3. Lubricate rotating parts and contact areas with a layer of industrial Vaseline to maintain smooth operation.
4. Inspect the contact surface meticulously and adjust the compression spring height to align with the specifications in Table II, ensuring perfect contact pressure.
5. Exclusively designed for hoisting applications, this switch integrates seamlessly with transformers on the line, optimizing operational efficiency.
6. Featuring a rated current range of 200-400 ampere hours, the switch typically utilizes three mounting holes, while the 600-1000A versions also require three mounting holes, ensuring stable installation.

Regular inspections every year are pivotal to ensure seamless functionality of the switch components:
Diligently remove any dirt from conductive parts, contact surfaces, and the insulating porcelain bottles' surface to maintain peak performance.

Conduct a thorough examination of all parts for any potential damage, paying particular attention to the insulating porcelain bottle for any signs of damage or cracks, ensuring longevity and safety.

Verify the quality of the contact surface of the conductive parts to ensure superior electrical performance.
