Product Description

Product Description

Introducing the revolutionary (H)GWBEB type outdoor high-voltage isolation switch, or isolation disconnect switch. Skillfully engineered for deployment on 10(12, 15, 24)kV high voltage power transmission and distribution lines, this state-of-the-art switch excels in opening and closing single-phase or three-phase circuits with effortless precision. It operates effectively without load while under voltage, ensuring peak safety and unwavering reliability.

This switch represents a pinnacle of engineering, crafted specifically for single-phase use within three-phase line systems. Its simple structure, cost-effectiveness, and ease of use make it a standout choice. Accommodating rated currents of 200, 400, 600, 800, 1000, and 1250 amps, it features a robust base, resilient post insulators, premium conductive parts, and an efficient mechanical section. The innovative gate knife structure optimizes circuit operations, with each phase's gate knife equipped with two conductive blades. External compression springs on each side deliver ideal contact pressure, adjustable via spring height modification. Operating the switch is a breeze with the insulated hook stick, complemented by a convenient self-locking device for enhanced security.

Working Environment:

Specifically designed to deliver flawless performance at altitudes of up to 1000 meters;

Expertly crafted to withstand ambient temperatures: maximum up to +40°C; minimum as low as -30°C;

Constructed to sustain operation with outdoor wind speeds reaching up to 35 meters/second;

Robustly built to withstand seismic intensities not surpassing 8 degrees; ideal for installation in areas with minimal severe vibrations.

For superior performance, ensure the installation site is free from gases, chemical deposits, salt mist, dust, dirt, or other explosive or corrosive elements that could compromise the switch's insulation and conductivity.

Note:

WHEN CONDITIONS SURPASS THE SPECIFIED NORMAL PARAMETERS, USERS ARE ADVISED TO CONSULT WITH THE COMPANY FOR OPTIMAL SOLUTIONS.

Installation, Use and Adjustment

Pre-installation work

1. Guarantee superior performance by thoroughly removing dust and debris from all components. Carefully clean the surface of the insulating porcelain bottle to preserve its integrity.
2. Meticulously clean the wiring surface of the ground screw to ensure optimal electrical contact.
3. To ensure smooth operation, apply a protective layer of industrial Vaseline to all rotating parts and contact areas.
4. Diligently inspect the contact surface. Adjust the compression spring height to ensure the contact pressure matches the specifications in Table II.
5. This switch is meticulously designed exclusively for hoisting use and is meant to function in perfect harmony with transformers on the line.
6. Supporting a rated current of 200-400 ampere hours, the switch typically employs three mounting holes. For 600-1000A, the configuration maintains three mounting holes for optimal stability.

Ensure enduring performance through annual inspections of the following components:
Carefully eliminate any dirt from conductive parts, contact surfaces, and the insulating porcelain bottle's surface to maintain functionality.

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

Verify that the contact surface of the conductive part is in impeccable condition, ensuring efficient operation.
