Product Description

Product Description

(H)GWBEB type outdoor high-voltage isolation switch, also known as an isolation disconnect switch, is meticulously crafted for seamless integration into 10(12, 15, 24)kV high voltage power transmission and distribution lines. This switch enables the efficient opening and closing of single-phase or three-phase circuits under the presence of voltage, although without load.

Designed specifically for single-phase utilization in three-phase line systems, this switch is renowned for its uncomplicated structure, affordability, and user-friendliness. Available in rated currents of 200, 400, 600, 800, 1000, and 1250 amps, its construction comprises a base, post insulators, conductive components, and a mechanical section. A sophisticated gate knife mechanism is employed for seamless circuit operation. Each phase's gate knife features dual conductive blades, augmented with external compression springs on both sides. By adjusting the spring height, optimal contact pressure for the gate knife is achieved. Operated via an insulated hook stick, the switch includes a self-locking device for enhanced security during switching operations.

Working Environment:

Altitude should not exceed 1000 meters;

Ambient temperature: must not surpass +40°C at maximum or fall below -30°C at minimum;

Outdoor wind speed should remain under 35 meters/second;

Seismic intensity should not exceed 8 degrees; the chosen installation location should avoid frequent severe vibrations.

The installation site must remain free of gases, chemical residues, salt mist, dust, dirt, or any explosive or corrosive substances that could gravely impact the switch's insulation and conductivity.

Note:

SHOULD THE NORMAL USE CONDITIONS ABOVE BE EXCEEDED, USERS MAY ENGAGE IN NEGOTIATIONS WITH THE COMPANY FOR CUSTOM SOLUTIONS.

Installation, Use and Adjustment

Pre-installation work

1. Thoroughly clean dust and dirt from all components, and delicately polish the surface of the insulating porcelain bottle.
2. Meticulously scrub the wiring surface of the ground screw for optimal connectivity.
3. Apply a protective layer of industrial Vaseline to the rotating parts and contact areas to ensure smooth operation.
4. Inspect the contact surfaces and adjust the compression spring height to align with the pressure specifications outlined in Table II.
5. This switch is strictly designed for hoisting use in conjunction with line transformers.
6. Rated currents for this switch range from 200-400 amps, typically requiring three mounting holes. Currents from 600-1000A also utilize three mounting holes.

Conduct annual inspections on the following switch components:
Eliminate any dirt from conductive parts, contact surfaces, and insulating porcelain bottle surfaces to maintain pristine conditions.

Inspect all components for potential damage, with particular attention to the insulating porcelain bottle for any signs of damage or cracks.

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