Product Description

Product Description

(H)GWBEB type outdoor high-voltage isolation switch, renowned in the industry as an isolation disconnect switch, is engineered with precision for optimal use on 10(12, 15, 24)kV high voltage power transmission and distribution lines. This switch empowers users with the capability to safely open and close single-phase or three-phase circuits, all while under voltage, but without any load. Its robust design ensures safety and reliability in critical applications.

Designed with versatility in mind, this switch excels in single-phase scenarios within three-phase line systems. It is celebrated for its straightforward construction, cost-efficiency, and user-friendliness. A variety of rated currents are accessible: 200, 400, 600, 800, 1000, and 1250 amps, each tailored to meet diverse operational requirements. This switch is composed of a sturdy base, reliable post insulators, conductive elements, and a mechanical section for seamless operation. The innovative gate knife structure is employed for efficiently opening and closing circuits. Each phase's gate knife is ingeniously crafted with two conductive blades, equipped with external compression springs on both sides to ensure optimal contact pressure. By adjusting the spring height, users can achieve the precise contact pressure needed for the switch's gate knife. The switch operates using an insulated hook stick for effortless actions, featuring a self-locking device for added security.

Working Environment:

Altitude permissible: not exceeding 1000 meters;

Ambient temperature range: maximum allowable +40°C; minimum threshold -30°C;

Outdoor wind velocity: restriction to 35 meters/second;

Seismic resilience: capable of withstanding intensity up to 8 degrees; Installation locations should remain free from recurrent severe vibrations.

Installation sites must remain devoid of gases, chemical deposits, salt mist, dust, dirt, or any explosive or corrosive mediums that could severely compromise the switch's insulation and conductive capabilities.

Note:

SHOULD THE ABOVE NORMAL OPERATING CONDITIONS BE EXCEEDED, USERS ARE ENCOURAGED TO DISCUSS OPTIONS WITH THE COMPANY.

Installation, Use and Adjustment

Pre-installation Procedures

1. Meticulously remove any dust or dirt from all components, ensuring the insulating porcelain bottle is cleaned to perfection.
2. Thoroughly scrub the wiring surface of the grounding screw.
3. Apply a protective layer of industrial Vaseline to all rotating parts and contact points to ensure smooth operation.
4. Inspect the contact surface rigorously, adjusting the compression spring's height to ensure contact pressure aligns with the specifications in Table II.
5. This switch is specifically designed for hoisting operations and is intended to be used in tandem with transformers on the power line.
6. The switch accommodates a rated current range of 200-400 amperes, typically utilizing three mounting holes. For currents between 600-1000A, three mounting holes are standard.

Conduct an annual examination of the following switch components:
Clear away any dirt from conductive parts, contact surfaces, and the insulating porcelain bottles' exterior.

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

Ensure that the contact surface of each conductive part maintains integrity and functionality.
