Product Description

Product Description

(H)GWBEB type outdoor high-voltage isolation switch, also renowned as an isolation disconnect switch, is meticulously engineered for seamless operation on 10(12, 15, 24)kV high voltage power transmission and distribution lines. This switch offers the capacity to open and close single-phase or three-phase circuits where voltage is present, but without the load, ensuring reliable performance.

Crafted for single-phase deployment within three-phase line systems, this switch stands out with its straightforward construction, cost-effectiveness, and user-friendly operation. The available rated currents range from 200 to 1250 amps, catering to diverse needs. This sophisticated switch comprises a robust base, sturdy post insulators, highly conductive components, and a mechanical assembly. The innovative gate knife structure facilitates efficient circuit opening and closing. Each phase’s gate knife incorporates two conductive blades, securely mounted with external compression springs on both sides. The contact pressure of the switch's gate knife is finely tuned by adjusting the spring height. Effortless operation is guaranteed through an insulated hook stick, complemented by a dependable self-locking mechanism for secure positioning.

Working Environment:

Altitude limitation: not to exceed 1000 meters; ensuring optimal performance.

Ambient temperature specifications: maximum of +40°C and a minimum of -30°C, tailored to withstand a wide range of environmental conditions.

Outdoor wind velocity: not to surpass 35 meters/second, maintaining stability in windy conditions.

Designed to endure seismic intensities up to 8 degrees, the installation site must avoid frequent severe vibrations to ensure longevity.

The installation site must remain free from gases, chemical deposits, salt mist, dust, dirt, and other explosive or corrosive elements that may significantly impact the switch's insulation and conductivity.

Note:

WHEN THE ABOVE NORMAL USE CONDITIONS ARE EXCEEDED, USERS ARE ADVISED TO ENGAGE IN DISCUSSION WITH THE COMPANY TO ARRANGE SUITABLE ALTERNATIVES OR SOLUTIONS.

Installation, Use, and Adjustment

Pre-installation work

1. Ensure all parts are thoroughly cleansed of dust and dirt, followed by a delicate wipe-down of the insulating porcelain bottle surface to maintain pristine conditions.
2. Clean the grounding screw's wiring surface meticulously to ensure flawless electrical connections.
3. A protective layer of industrial Vaseline should be applied to rotating parts and contact areas to reduce friction and enhance durability.
4. Inspect the contact surface diligently and adjust the height of the compression spring to meet the specified contact pressure as outlined in Table II.
5. Specifically designed for hoisting applications, this switch is optimized for integration with transformers along the line, ensuring seamless functionality.
6. This switch, with a rated current of 200-400 ampere hours, typically utilizes three mounting holes. For currents between 600-1000A, a similar three-hole mounting configuration is employed for stability.

Conduct an annual inspection of the switch, focusing on the following components:
Remove any accumulated dirt from conductive parts, contact surfaces, and the insulating porcelain bottle's surface to maintain optimal functionality.

Examine all components for possible damage, with particular attention to any signs of damage or cracks in the insulating porcelain bottle.

Ensure the conductive part's contact surface maintains excellent condition for efficient electrical conductivity.
