Product Description

Product Description

Introducing the (H)GWBEB type outdoor high-voltage isolation switch, often referred to as an isolation disconnect switch. This innovative product is meticulously crafted for seamless integration with 10(12, 15, 24)kV high voltage power transmission and distribution lines. It expertly handles the opening and closing of single-phase or three-phase circuits while the voltage remains intact, ensuring unmatched efficiency and reliability.

Our switch is specifically designed for single-phase operation within three-phase line systems, highlighting its simplistic design, affordability, and user-friendly nature. Available with rated currents of 200, 400, 600, 800, 1000, and 1250 amps, these switches are composed of a sturdy base, resilient post insulators, conductive elements, and a robust mechanical section. The ingenious gate knife structure facilitates circuit engagement and disengagement. Each phase's gate knife incorporates two conductive blades, supported by external compression springs on either side. By adjusting the spring height, the optimal contact pressure of the gate knife is achieved. The switch operation is controlled via an insulated hook stick, ensuring safe opening and closing, complemented by a reliable self-locking mechanism.

Working Environment:

Altitude requirements: not exceeding 1000 meters;

Ambient temperature: ideally ranging from a maximum of +40°C to a minimum of -30°C;

Accommodates outdoor wind speeds up to 35 meters per second;

Designed to withstand seismic intensities up to 8 degrees; the installation site should be free from frequent severe vibrations.

To ensure optimal performance and longevity, the installation site must be devoid of gases, chemical deposits, salt mist, dust, dirt, or any other explosive or corrosive agents that could compromise the switch's insulation and conductivity.

Note:

FOR CONDITIONS EXCEEDING THE ABOVE NORMAL USE SPECIFICATIONS, USERS ARE ENCOURAGED TO DISCUSS ALTERNATIVE SOLUTIONS WITH THE COMPANY.

 

Installation, Use and Adjustment

Pre-installation work

1. Thoroughly remove any dust and grit from components, and delicately cleanse the surface of the insulating porcelain bottle for optimal function.
2. Ensure the wiring surface of the ground screw is clean and scrubbed for superior connectivity.
3. Safeguard the rotating parts and contact areas by applying a protective layer of industrial Vaseline.
4. Inspect the contact surface meticulously and adjust the compression spring's height to ensure the contact pressure aligns with the specifications in Table II.
5. This switch is specifically designed for hoisting applications and is intended to be utilized in conjunction with the transformer on the line.
6. The switch's rated current ranges from 200-400 ampere hours typically, utilizing three mounting holes, with 600-1000A configurations also making use of three mounting holes.

Conduct a thorough annual inspection of the following switch components:
Meticulously clear all dirt from conductive parts, contact surfaces, and the surface of insulating porcelain bottles to maintain peak performance.

Diligently examine all components for potential damage, with particular focus on detecting any damage or cracks in the insulating porcelain bottle.

Ensure the contact surface of the conductive part remains in excellent condition.
