Product Description

Product Description

(H)GWBEB type outdoor high-voltage isolation switch, also recognized as an isolation disconnect switch, is expertly crafted for 10(12, 15, 24)kV high voltage power transmission and distribution systems. This essential component is engineered to open and close single-phase or three-phase circuits operating with voltage but without carrying any load.

Designed for seamless integration in three-phase line systems, the switch is celebrated for its straightforward structure, economic viability, and user-friendly operation. It comes in a range of rated currents, including 200, 400, 600, 800, 1000, and 1250 amps. The switch is composed of a robust base, reliable post insulators, conductive elements, and a precise mechanical section. Utilizing an innovative gate knife structure, the switch efficiently opens and closes circuits. Each phase's gate knife includes dual conductive blades with external compression springs on both sides to ensure optimal contact pressure, adjustable through spring height modifications. An insulated hook stick facilitates smooth operational opening and closing actions, complemented by a secure self-locking mechanism.

Working Environment:

Altitude should not surpass 1000 meters;

Ambient temperature must remain within a maximum of +40°C and a minimum of -30°C;

Outdoor wind velocities should not exceed 35 meters/second;

Seismic intensity up to 8 degrees is permissible; the installation environment must be free from frequent intense vibrations.

The installation site should be devoid of gases, chemical deposits, salt mist, dust, dirt, and any other explosive or corrosive substances that could seriously compromise the switch's insulation and conductivity.

Note:

SHOULD THE NORMAL OPERATING CONDITIONS MENTIONED ABOVE BE SURPASSED, A NEGOTIATION WITH THE COMPANY IS RECOMMENDED.

Installation, Use and Adjustment

Pre-installation work

1. Thoroughly remove dust and debris from all parts, and gently cleanse the surface of the insulating porcelain bottle for optimal performance.
2. Carefully scrub the wiring surface of the ground screw.
3. Generously apply a layer of industrial Vaseline to both the rotating parts and contact areas to ensure smooth operation.
4. Verify the contact surfaces and adjust the compression spring height to ensure the contact pressure is in accordance with Table II.
5. This switch is specifically designed for hoisting applications and intended to be used in conjunction with transformers along the line.
6. This switch accommodates rated currents between 200-400 ampere hours, typically utilizing three mounting holes. For currents between 600-1000A, three mounting holes are also used.

Conduct an annual inspection of the following switch components:
Eliminate dirt from conductive parts, contact interfaces, and insulating porcelain bottle surfaces to maintain optimal conductivity.

Inspect all components for any damage, paying particular attention to the insulating porcelain bottle to detect any cracks or impairments.

Ensure that the contact surfaces of the conductive parts maintain excellent condition.
