Product Description

Product Description

Introducing the (H)GWBEB type outdoor high-voltage isolation switch, an essential asset for your 10(12, 15, 24)kV high voltage power transmission and distribution needs. Commonly referred to as an isolation disconnect switch, this device is expertly crafted to manage the opening and closing of single-phase or three-phase circuits while under voltage, but without load.

This switch is uniquely engineered for single-phase functionality in three-phase line systems, boasting a straightforward design that is both economical and user-friendly. Offered in a variety of rated currents—200, 400, 600, 800, 1000, and 1250 amps—these switches comprise a robust base, durable post insulators, reliable conductive components, and an efficient mechanical section. Featuring a gate knife design for circuit operations, each phase includes dual conductive blades with external compression springs. Adjusting spring height ensures optimal contact pressure for the gate knife's operation. The switch is manipulated with an insulated hook stick and includes a secure self-locking mechanism.

Working Environment:

Designed for altitudes not exceeding 1000 meters;

Suitable for ambient temperatures with a maximum of +40°C and a minimum of -30°C;

Capable of withstanding outdoor wind speeds up to 35 meters per second;

Withstands seismic activity up to 8 degrees, ensuring stability in areas free from frequent severe vibrations.

Ideal installation sites are free from gases, chemical deposits, salt mist, dust, dirt, or other explosive or corrosive mediums that could impact the switch's insulation and conductivity.

Note:

IF THE STANDARD USAGE CONDITIONS ARE EXCEEDED, USERS ARE INVITED TO DISCUSS CUSTOM SOLUTIONS WITH OUR COMPANY.

Installation, Use and Adjustment

Pre-installation work

1. Thoroughly clean dust and grime from all components, paying special attention to the insulating porcelain bottle surfaces.
2. Ensure the ground screw's wiring surface is scrubbed clean.
3. Apply a protective layer of industrial Vaseline to all rotating parts and contact areas to ensure smooth operation.
4. Verify the contact surface and adjust compression spring height to meet the specifications outlined in Table II, ensuring proper contact pressure.
5. This switch is exclusively designed for hoisting applications and should be used in tandem with line transformers for optimal performance.
6. Rated for currents between 200-400 ampere hours, typically requiring three mounting holes. For 600-1000A, three mounting holes are standard.

Conduct an annual inspection of the following switch components:
Remove any accumulated dirt from conductive parts, contact surfaces, and insulating porcelain bottle exteriors.

Inspect all components for signs of damage, with a particular focus on assessing the insulating porcelain bottle for cracks or damage.

Evaluate the quality of the contact surface on the conductive parts to ensure optimal performance.
