Product Description

Product Description

(H)GWBEB Type Outdoor High-Voltage Isolation Switch, also renowned as the 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 open and close single-phase or three-phase circuits while voltage is present, yet without load.

Crafted for single-phase application within three-phase line systems, this switch stands out with its uncomplicated structure, economic viability, and user-friendly nature. It offers a versatile range of rated currents comprising 200, 400, 600, 800, 1000, and 1250 amps. Each switch incorporates a base, post insulators, conductive elements, and a mechanical section. Its gate knife design facilitates circuit operations, consisting of a pair of conductive blades per phase, complemented by external compression springs for optimal performance. Adjusting the spring height fine-tunes the requisite contact pressure. Operations are conducted with an insulated hook stick, complemented by a self-locking mechanism for security.

Working Environment:

Operational altitude must not exceed 1000 meters;

Ambient temperature parameters: a maximum of +40°C and a minimum of -30°C;

Outdoor wind velocity threshold is 35 meters/second;

Seismic resistance up to 8 degrees; installation venues should remain free from recurrent severe vibrations.

The installation environment should be devoid of gases, chemical residues, salt mist, dust, dirt, or any other explosive or corrosive elements that could severely compromise the switch’s insulation and conductive properties.

Note:

FOR CONDITIONS SURPASSING THE ABOVE-NORMAL USE PARAMETERS, USERS ARE ADVISED TO ENGAGE IN DISCUSSIONS WITH THE COMPANY.

Installation, Use, and Adjustment

Pre-installation Procedures

1. Eliminate dust and dirt from components, ensuring the insulating porcelain bottle surfaces are meticulously cleaned.
2. Thoroughly cleanse the wiring interfaces of the ground screws.
3. Administer a coat of industrial Vaseline over the rotating components and contact areas for optimal functionality.
4. Assess the contact surfaces and modify the compression spring height to align the contact pressure with Table II standards.
5. This switch is exclusively designed for hoisting applications and is intended for cooperative use with transformers along the line.
6. The switch's rated current spans 200-400 ampere hours, typically employing three mounting holes. The 600-1000A series also utilizes three mounting holes.

Annual Inspection Recommendations:
Consistently clear dirt from conductive components, contact surfaces, and the insulating porcelain bottle's exterior.

Vigilantly inspect all components for signs of damage, with particular attention to the insulating porcelain bottle for any cracks or harm.

Ensure the integrity of the conductive part's contact surface.
