Product Description

Product Description

(H)GWBEB type outdoor high-voltage isolation switch, fondly termed as the isolation disconnect switch, is crafted meticulously for deployment on 10(12, 15, 24)kV high voltage power transmission and distribution lines. This sophisticated device is engineered to manage the seamless opening and closing of single-phase or three-phase circuits, skillfully handling situations where a load is absent yet voltage is present.

Our switch is meticulously curated for single-phase operation within three-phase line systems. Distinguished by its uncomplicated design, this switch offers affordability and unparalleled ease of use. It is available in a variety of rated currents including 200, 400, 600, 800, 1000, and an impressive 1250 amps. The switch is a masterpiece of engineering, comprising a base, robust post insulators, high-conductivity parts, and a meticulously designed mechanical section. It employs a gate knife structure for circuit operations. Each phase's gate knife features two conductive blades, enhanced with external compression springs on both sides for optimal performance. Precise adjustment of the spring height ensures the necessary contact pressure for flawless switch operation. The switch's operations, including opening and closing, are seamlessly carried out using an insulated hook stick and it boasts a reliable self-locking device to enhance safety.

Working Environment:

Altitude must not exceed 1000 meters;

Ambient temperature: soaring to a maximum of +40°C and dipping to a minimum of -30°C;

Outdoor wind velocity should not surpass 35 meters/second;

Seismic intensity is restrained to 8 degrees; the installation site must be free from frequent intense vibrations.

The installation environment should be devoid of gases, chemical residues, salt mist, dust, grime, or any other explosive or corrosive substances that could significantly impair the switch's insulation and conductivity.

Note:

SHOULD THE AFOREMENTIONED NORMAL USAGE CONDITIONS BE EXCEEDED, USERS ARE INVITED TO ENGAGE IN DISCUSSIONS WITH OUR COMPANY TO FIND OPTIMAL SOLUTIONS.

 

Installation, Use and Adjustment

Pre-installation work

1. Eradicate all dust and debris from the parts, ensuring a thorough cleansing of the insulating porcelain bottle's surface.
2. Diligently clean the wiring surface of the ground screw to ensure optimal connectivity.
3. Apply a protective coating of industrial Vaseline to the rotating parts and contact areas to enhance performance and longevity.
4. Conduct a meticulous inspection of the contact surface, adjusting the height of the compression spring meticulously to ensure that contact pressure adheres to the specifications outlined in Table II.
5. This switch is exclusively designed for hoisting applications and is perfectly complemented when used in conjunction with transformers on the line.
6. The switch's rated current ranges from 200 to 400 ampere hours, generally utilizing three mounting holes. For currents of 600 to 1000A, three mounting holes are similarly employed to ensure secure installation.

Conduct an annual inspection, meticulously evaluating the following components of the switch:
Diligently remove any impurities from conductive components, contact surfaces, and the surface of insulating porcelain bottles to maintain operational excellence.

Scrutinize all components meticulously for any signs of damage, giving particular attention to the insulating porcelain bottle to detect any damage or cracks.

Ensure that the contact surface of the conductive part maintains its integrity and performance.
