Product Description

Product Description

Presenting the (H)GWBEB type outdoor high-voltage isolation switch, also renowned as an isolation disconnect switch. This innovative device is meticulously designed for application on 10(12, 15, 24)kV high voltage power transmission and distribution lines to efficiently open and close single-phase or three-phase circuits without load while voltage remains present.

This switch is perfectly crafted for single-phase applications within three-phase line systems and stands out due to its simple structure, cost-effectiveness, and exceptional ease of use. With available rated currents of 200, 400, 600, 800, 1000, and 1250 amps, these switches are composed of a stable base, durable post insulators, conductive parts, and a robust mechanical section. Employing a gate knife structure for seamless circuit operations, each phase's gate knife consists of two highly conductive blades, enhanced with external compression springs on either side. The height adjustment of these springs ensures optimal contact pressure for the switch's gate knife. An insulated hook stick facilitates the switching operations, complemented by a reliable self-locking mechanism for enhanced safety.

Working Environment:

Designed for altitudes not exceeding 1000 meters; this switch is engineered to perform efficiently.

It thrives in ambient temperatures ranging from a maximum of +40°C to a minimum of -30°C; ensuring reliability across a wide temperature spectrum.

Capable of withstanding outdoor wind speeds of up to 35 meters per second; offering steadfast resilience.

Rated for seismic intensities not exceeding 8 degrees; ideal for locations with minimal severe vibrations.

The installation site must remain free from harmful gases, chemical deposits, salt mist, dust, dirt, and other explosive or corrosive substances that could severely impact the switch's insulation and conductivity.

Note:

SHOULD THE ABOVE STANDARD USE CONDITIONS BE EXCEEDED, USERS ARE ENCOURAGED TO NEGOTIATE WITH THE COMPANY FOR CUSTOM SOLUTIONS.

Installation, Use and Adjustment

Pre-installation Work

1. Ensure all parts are free from dust and dirt, meticulously cleaning the surface of the insulating porcelain bottle for optimal performance.
2. Thoroughly clean the wiring surface of the ground screw to maintain strong electrical connections.
3. Apply a protective layer of industrial Vaseline on the rotating parts and contact areas to ensure smooth operations.
4. Inspect the contact surface and finely adjust the compression spring height to align with the defined parameters in Table II, thereby assuring optimal contact pressure.
5. This switch is specifically designed for hoisting use and is intended to be used in conjunction with transformers on the line, enhancing system efficiency.
6. The rated current of this versatile switch ranges between 200-400 ampere hours, typically utilizing three mounting holes. For currents between 600-1000A, three mounting holes are used to ensure stability.

Schedule annual inspections to maintain the integrity and functionality of the switch:
Thoroughly clean dirt from conductive parts, contact surfaces, and insulating porcelain bottle surfaces to maintain performance.

Conduct a comprehensive damage assessment on all parts, with particular attention to potential damages or cracks in the insulating porcelain bottle.

Evaluate the condition of the conductive parts' contact surfaces to ensure continued operational excellence.
