Product Description

Product Description

Introducing the (H)GWBEB type Outdoor High-Voltage Isolation Switch – an unparalleled isolation disconnect switch crafted for impeccable performance on 10(12, 15, 24)kV high voltage power transmission and distribution lines. This distinguished device is engineered to seamlessly open and close single-phase or three-phase circuits even with voltage present, ensuring top-line efficiency and reliability.

Designed for single-phase excellence in three-phase line systems, this switch stands out with its simplistic structure, budget-friendly nature, and user-friendly operation. With rated currents of 200, 400, 600, 800, 1000, and 1250 amps, these switches boast a formidable construction comprising a sturdy base, reliable post insulators, and enduring conductive and mechanical parts. The sophisticated gate knife structure guarantees smooth circuit operations. Every phase's gate knife showcases dual conductive blades, reinforced by external compression springs on either side. Tailoring the spring height achieves the precise contact pressure essential for flawless switch operation. Operable with an insulated hook stick for seamless opening and closing, it also features an ingenious self-locking device for added safety.

Working Environment:

Optimal operation at altitudes not exceeding 1000 meters;

Perfect performance within an ambient temperature range from a soaring +40°C to a chilly -30°C;

Thrives in outdoor conditions with wind speeds up to 35 meters/second;

Withstands seismic intensities up to 8 degrees; ideally suited for installation sites free from frequent severe vibrations.

The installation site must be devoid of gases, chemical residues, salt mist, dust, dirt, or any other explosive or corrosive elements that could significantly impair the switch's insulation and conductivity.

Note:

SHOULD THE STANDARD OPERATING CONDITIONS BE SURPASSED, USERS ARE ENCOURAGED TO DISCUSS WITH THE COMPANY FOR A CUSTOMIZED SOLUTION.

Installation, Use, and Adjustment

Pre-installation work

1. Begin by meticulously removing dust and dirt from all components, ensuring the insulating porcelain bottle surfaces are flawlessly clean.
2. Thoroughly scrub the ground screw's wiring surface to ensure optimal connectivity.
3. Coat rotating parts and contact areas with a protective layer of industrial Vaseline for enhanced longevity.
4. Inspect contact surfaces and fine-tune the compression spring height to meet the standards detailed in Table II, ensuring optimal contact pressure.
5. This switch excels when used exclusively for hoisting applications, seamlessly integrating with transformers on the line.
6. With a rated current spectrum of 200-400 amps, typically utilizing three mounting holes, and extending to 600-1000A configurations also employing three mounting holes.

Annual Maintenance Recommendations: Inspect these critical components each year:
Meticulously eliminate dirt from conductive parts, contact surfaces, and insulating porcelain bottle surfaces to maintain peak performance.

Conduct thorough checks for any component damage, paying particular attention to the insulating porcelain bottle for cracks or other damage.

Ensure the conductive part's contact surface remains in excellent condition for consistent functionality.
