Product Description

Product Description

Introducing the (H)GWBEB type Outdoor High-Voltage Isolation Switch, also known as the Isolation Disconnect Switch. This cutting-edge technology is crafted for superior performance on 10(12, 15, 24)kV high voltage power transmission and distribution lines. Expertly engineered to open and close single-phase or three-phase circuits, this switch operates seamlessly with voltage present, yet without load, ensuring maximum safety and reliability.

Ideal for single-phase applications in three-phase systems, this switch boasts a simple, cost-effective, and user-friendly design. With rated currents of 200, 400, 600, 800, 1000, and 1250 amps, it offers versatility and adaptability. The construction features a robust base, durable post insulators, conductive components, and a precision-engineered mechanical section. Utilizing a sophisticated gate knife structure, the switch deftly manages circuit operations. Each phase's gate knife includes two conductive blades, enhanced with external compression springs for optimal performance. The spring height is adjustable to ensure the required contact pressure. Operated with an insulated hook stick, the switch also includes a state-of-the-art self-locking device for secure handling.

Working Environment:

Optimally designed for altitudes below 1000 meters,

Crafted to perform in ambient temperatures from a chilly -30°C up to a warm +40°C.

Engineered to withstand outdoor wind speeds up to 35 meters/second,

Resilient against seismic intensities up to 8 degrees, ensuring stability in areas without excessive vibrations.

Installation sites must be free from harmful gases, chemical deposits, salt mist, dust, dirt, or other corrosive or explosive elements that could adversely affect insulation and conductivity.

Note:

IF THE CONDITIONS FOR NORMAL USE EXCEED THE SPECIFIED LIMITS, WE WELCOME USERS TO CONSULT WITH THE COMPANY FOR CUSTOM SOLUTIONS.

 

Installation, Use and Adjustment

Pre-installation work

1. Thoroughly remove dust and dirt from all components, ensuring the insulating porcelain bottle surfaces are meticulously clean.
2. Carefully scrub the wiring area of the ground screw to ensure pristine connectivity.
3. Generously apply a coat of industrial Vaseline to all rotating parts and contact zones for smooth operation.
4. Inspect the contact surfaces and adjust the compression spring height to conform precisely with Table II specifications, ensuring adequate contact pressure.
5. This switch is exclusively designed for hoisting applications, intended for use in tandem with transformers along the line.
6. Designed for versatility, the switch with rated currents of 200-400 ampere hours typically utilizes three mounting holes, while those rated 600-1000A also employ three mounting holes.

An annual inspection protocol should include the following checks:
Remove any accumulated dirt from conductive parts, contact surfaces, and insulating porcelain bottle surfaces to maintain peak performance.

Conduct a thorough inspection of all components, paying special attention to the integrity of the insulating porcelain bottle for any signs of damage or cracks.

Ensure that the conductive part's contact surface remains impeccable and optimal for superior functionality.
