Product Description

Product Description

(H)GWBEB type outdoor high-voltage isolation switch, often referred to as an isolation disconnect switch, is meticulously engineered to operate on 10(12, 15, 24)kV high voltage power transmission and distribution lines. This switch is adept at safely opening and closing single-phase or three-phase circuits while maintaining voltage. An ideal solution for reliable power management.

This switch is specifically crafted for single-phase usage within three-phase line systems. Its standout features include a straightforward design, cost-efficiency, and user-friendliness. Available rated currents are 200, 400, 600, 800, 1000, and 1250 amps. The switch is composed of a sturdy base, robust post insulators, high-conductivity parts, and a precision mechanical section. Employing a gate knife structure for circuit operation, each phase's gate knife integrates two conductive blades, bolstered with external compression springs on either side. The spring height is adjustable to ensure optimal contact pressure. An insulated hook stick facilitates operation, and a self-locking device enhances safety.

Working Environment:

The installation altitude should not exceed 1000 meters;

Ambient temperature conditions: a maximum of +40°C and a minimum of -30°C;

Outdoor wind speeds should remain below 35 meters per second;

Seismic intensity should not surpass 8 degrees; the site must not endure frequent severe vibrations.

The location should be free from gases, chemical deposits, salt mist, dust, dirt, or any other explosive or corrosive substances that could deteriorate the switch’s insulation and conductivity.

Note:

WHEN THE ABOVE NORMAL USE CONDITIONS ARE EXCEEDED, USERS ARE ENCOURAGED TO DISCUSS WITH THE COMPANY FOR ALTERNATIVE ARRANGEMENTS.

Installation, Use and Adjustment

Pre-installation work

1. Eliminate dust and dirt from all components, and meticulously clean the insulating porcelain bottle surface.
2. Thoroughly scrub the wiring surface of the grounding screw.
3. Apply a protective layer of industrial Vaseline to all rotating parts and contact areas for smooth operation.
4. Inspect the contact surfaces and adjust the compression spring height to ensure the contact pressure meets the standards outlined in Table II.
5. This switch is specifically designed for hoisting applications and should be used in tandem with the transformer on the line.
6. The switch's rated current is between 200-400 ampere hours, typically utilizing three mounting holes. For 600-1000A applications, three mounting holes are also used.

Conduct an annual inspection of the following switch components:
Cleanse dirt from conductive parts, contact surfaces, and the insulating porcelain bottle's surface.

Examine all components for damage, with particular attention to checking the insulating porcelain bottle for any damage or cracks.

Verify that the contact surface of the conductive part is in optimal condition.
