Product Description

Product Description

(H)GWBEB type outdoor high-voltage isolation switch, often referred to as an isolation disconnect switch, is masterfully engineered for operation on 10(12, 15, 24)kV high voltage power transmission and distribution lines. This essential device is adept at opening and closing single-phase or three-phase circuits while voltage is present, ensuring seamless operation without load.

The switch is crafted for single-phase use within three-phase line systems. It stands out for its straightforward design, affordability, and user-friendly operation. With an array of rated currents available - 200, 400, 600, 800, 1000, and 1250 amps - this versatile switch integrates a base, post insulators, conductive components, and a mechanical section. Utilizing a gate knife structure, it adeptly manages circuit opening and closing. Each phase's gate knife includes two conductive blades complemented by external compression springs on both sides. By adjusting the spring height, the required contact pressure for the switch's gate knife is effortlessly achieved. An insulated hook stick ensures smooth and safe operation, while a self-locking device adds an extra layer of security.

Working Environment:

Altitude must not exceed 1000 meters;

Ambient temperature: ranges from a splendid maximum of +40°C to a chilly minimum of -30°C;

Outdoor wind velocity should not surpass 35 meters/second;

Seismic intensity is limited to 8 degrees; installation sites should remain free from frequent severe vibrations to ensure optimal performance.

The installation site should remain devoid of gases, chemical deposits, salt mist, dust, dirt, or any other explosive or corrosive mediums that could significantly impair the switch's insulation and conductivity.

Note:

IF THE ABOVE NORMAL USE CONDITIONS ARE EXCEEDED, THE USER IS ENCOURAGED TO DISCUSS CUSTOM SOLUTIONS WITH THE COMPANY.

Installation, Use and Adjustment

Pre-installation work

1. Thoroughly clean the parts from dust and grime, and gently wipe the insulating porcelain bottle's surface to ensure pristine condition.
2. Meticulously scrub the wiring surface of the ground screw for optimal connectivity.
3. Apply a protective layer of industrial Vaseline to the rotating parts and contact areas to prevent wear and enhance performance.
4. Inspect the contact surface and adjust the compression spring's height to ensure contact pressure aligns with the precise standards outlined in Table II.
5. This switch is meticulously designed exclusively for hoisting use and is intended to work harmoniously with the transformer along the line.
6. For rated currents of 200-400 ampere hours, typically three mounting holes are utilized, while for 600-1000A, the same configuration applies, ensuring secure and reliable installation.

Undertake an annual routine check of the following switch components:
Diligently remove any dirt from the conductive parts, contact surfaces, and the insulating porcelain bottles' exterior to maintain pristine conditions.

Inspect all components for any signs of damage, with particular focus on the insulating porcelain bottle for any damage or cracks.

Ensure the contact surface of the conductive part remains in excellent condition for seamless operation.
