Product Description

Product Description

(H)GWBEB type outdoor high-voltage isolation switch, commonly referred to as an isolation disconnect switch, is meticulously engineered for deployment on 10(12, 15, 24)kV high voltage power transmission and distribution lines. It efficiently facilitates the opening and closing of single-phase or three-phase circuits, maintaining voltage presence without load.

Tailored for single-phase applications within three-phase line systems, this switch is renowned for its uncomplicated design, economical viability, and user-friendly operation. It offers rated currents of 200, 400, 600, 800, 1000, and 1250 amps. Comprising a base, post insulators, conductive elements, and a mechanical section, the switch employs a gate knife structure for efficient circuit management. Each phase's gate knife integrates dual conductive blades, supported by external compression springs on both flanks. Adjusting spring height ensures optimal contact pressure for effective gate knife operation. The switch is maneuvered using an insulated hook stick, featuring a self-locking mechanism for seamless operations.

Working Environment:

Ideally situated at altitudes not surpassing 1000 meters;

Operates within ambient temperatures: a maximum of +40°C and a minimum of -30°C;

Sustains outdoor wind speeds not exceeding 35 meters/second;

Designed for seismic intensities not surpassing 8 degrees, ensuring stability without frequent severe vibrations at the installation locale.

The installation site must be free from gases, chemical deposits, salt mist, dust, dirt, and other explosive or corrosive substances that can severely impair the switch's insulation and electrical conductivity.

Note:

WHEN CONDITIONS EXCEED THE SPECIFIED NORMAL USE PARAMETERS, USERS ARE ENCOURAGED TO NEGOTIATE WITH THE COMPANY FOR CUSTOM SOLUTIONS.

Installation, Use and Adjustment

Pre-installation work

1. Meticulously clear dust and debris from all components, meticulously cleansing the surface of the insulating porcelain bottle.
2. Thoroughly scrub the wiring surfaces of the ground screw to ensure optimal connectivity.
3. Apply a generous layer of industrial Vaseline to the rotating components and contact zones to enhance durability and performance.
4. Inspect the contact surfaces, adjusting the compression spring height to ensure contact pressure aligns with Table II specifications.
5. This switch is specifically engineered for hoisting applications and functions integrally with line transformers.
6. Switch rated current ranges from 200-400 ampere hours, typically requiring only three mounting holes. For 600-1000A, three mounting holes remain sufficient.

Conduct an annual inspection of the following switch components:
Ensure removal of all contaminants from conductive parts, contact surfaces, and insulating porcelain bottle surfaces.

Examine all components for potential damage, with particular focus on inspecting the insulating porcelain bottle for any signs of damage or cracking.

Assess the integrity of the contact surfaces within the conductive components.
