Product Description

Product Description

(H)GWBEB type outdoor high-voltage isolation switch, also heralded as an isolation disconnect switch, is meticulously crafted for deployment on 10(12, 15, 24)kV high voltage power transmission and distribution lines. It efficiently manages the opening and closing of single-phase or three-phase circuits, ensuring operations occur with voltage present but without load.

This switch, tailored for single-phase application within three-phase line systems, stands out for its simplistic design, affordability, and user-friendly operations. Available rated currents are 200, 400, 600, 800, 1000, and 1250 amps. The switches comprise a robust base, post insulators, conductive components, and a mechanical section. A sophisticated gate knife mechanism enables seamless circuit operations. Each phase's gate knife includes two conductive blades, complemented by external compression springs on both ends. Spring height adjustments create the optimal contact pressure for superior functionality. An insulated hook stick facilitates operational actions, complete with a self-locking device for enhanced security.

Working Environment:

Ideal for altitudes not exceeding 1000 meters;

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

Outdoor wind speed should not surpass 35 meters/second;

Designed to withstand seismic intensity up to 8 degrees; the installation site should be stable without frequent severe vibrations.

Installation sites must be free from gases, chemical deposits, salt mist, dust, dirt, or other explosive or corrosive elements that could adversely impact the switch's insulation and conductivity.

Note:

IF THE ABOVE NORMAL OPERATING CONDITIONS ARE EXCEEDED, USERS ARE ENCOURAGED TO DISCUSS OPTIONS WITH THE COMPANY.

 

Installation, Use and Adjustment

Pre-installation work

1. Carefully remove dust and dirt from all components, and meticulously clean the surface of the insulating porcelain bottle.
2. Thoroughly clean the wiring surface of the ground screw to ensure optimal connectivity.
3. Apply a protective layer of industrial Vaseline to all rotating components and contact zones to enhance durability.
4. Inspect the contact surface and adjust the compression spring height to meet the specifications outlined in Table II.
5. This switch is exclusively designed for hoisting purposes and is intended to be used in tandem with transformers on the line.
6. The rated current capacity for this switch ranges from 200-400 ampere hours, with typically three mounting holes employed. For 600-1000A, three mounting holes are standard.

Ensure regular annual inspections of the following switch components:
Consistently remove any dirt from conductive parts, contact surfaces, and the insulating porcelain bottles to maintain peak performance.

Inspect all components for damage, with a focus on identifying any damage or cracks in the insulating porcelain bottle.

Verify that the contact surface of conductive parts remains in excellent condition.
