Product Description

Product Description

Unveiling the (H)GWBEB type outdoor high-voltage isolation switch, this remarkable device, also known as an isolation disconnect switch, is meticulously engineered for deployment on 10(12, 15, 24)kV high voltage power transmission and distribution lines. Its primary function is to efficiently open and close single-phase or three-phase circuits while maintaining voltage presence, yet without a load.

This switch is tailored for single-phase operations within three-phase line systems. It stands out due to its streamlined structure, affordability, and user-friendly design. It is available in a wide range of rated currents including 200, 400, 600, 800, 1000, and 1250 amps. Structurally, these switches are composed of a base, post insulators, conductive components, and a mechanical section. The innovative gate knife structure facilitates circuit operations. Each phase's gate knife is equipped with two conductive blades and features external compression springs on both sides. By adjusting the spring height, the required contact pressure for the switch's gate knife is ensured. Operation is conducted with an insulated hook stick for seamless opening and closing actions, complemented by a self-locking device.

Working Environment:

Designed to operate at altitudes not exceeding 1000 meters;

Capable of withstanding ambient temperatures: with a maximum not exceeding +40°C and a minimum not dropping below -30°C;

Engineered to endure outdoor wind speeds not exceeding 35 meters/second;

Built to tolerate seismic intensity not exceeding 8 degrees, with the installation site free from frequent and severe vibrations.

The installation site must be devoid of gases, chemical deposits, salt mist, dust, dirt, or other explosive or corrosive mediums that could significantly impair the switch's insulation and conductivity.

Note:

IN INSTANCES WHERE THE ABOVE NORMAL USE CONDITIONS ARE SURPASSED, USERS ARE ENCOURAGED TO CONSULT WITH OUR COMPANY FOR FURTHER NEGOTIATIONS.

 

Installation, Use and Adjustment

Pre-installation work

1. Thoroughly clean dust and dirt from all parts, ensuring the insulating porcelain bottle's surface is meticulously wiped.
2. Carefully scrub the wiring surface of the ground screw to ensure optimal performance.
3. Apply a protective layer of industrial Vaseline to the rotating parts and areas of contact to enhance durability.
4. Examine the contact surface and meticulously adjust the height of the compression spring to ensure the contact pressure aligns with the specifications outlined in Table II.
5. This switch is expressly designed for hoisting use and is intended to be used in conjunction with the line transformer.
6. The switch comes with a rated current range of 200-400 ampere hours, typically utilizing only three mounting holes. The 600-1000A variants also employ three mounting holes for secure installation.

Conduct an annual inspection of the following switch components:
Diligently remove any accumulated dirt from conductive parts, contact surfaces, and the insulating porcelain bottles' exterior.

Inspect all components for potential damage, with a particular focus on identifying any issues with the insulating porcelain bottle, such as damage or cracks.

Examine the conductive part's contact surface to ensure optimal integrity and performance.
