Product Description

Product Description

Introducing the (H)GWBEB type outdoor high-voltage isolation switch, also renowned as the isolation disconnect switch. This cutting-edge equipment is expertly engineered for deployment on 10(12, 15, 24)kV high voltage power transmission and distribution lines, adeptly handling the opening and closing of single-phase or three-phase circuits without load, yet maintaining voltage presence.

This high-performance switch is specifically crafted for single-phase operations within three-phase line systems and stands out with its simplicity, cost-efficiency, and user-friendly nature. With a selection of rated currents from 200 to 1250 amps, these switches are composed of a robust base, sturdy post insulators, conductive elements, and a precise mechanical section. The innovative gate knife structure facilitates seamless circuit management. Each phase's gate knife is fortified with dual conductive blades, externally supported by compression springs for optimal contact pressure adjustment. Operated with an insulated hook stick, this switch ensures secure opening and closing, further secured by a sophisticated self-locking device.

Working Environment:

Optimally designed for altitudes not exceeding 1000 meters;

Ensures peak performance within ambient temperatures: with a maximum threshold of +40°C and a minimum of -30°C;

Built to withstand outdoor wind speeds not surpassing 35 meters/second;

Engineered to endure seismic intensity levels up to 8 degrees, with installation sites free from frequent severe vibrations.

The installation environment must be devoid of gases, chemical deposits, salt mist, dust, dirt, or other elements that could explosively or corrosively compromise the switch's insulation and conductive capabilities.

Note:

WHEN NORMAL USE CONDITIONS ARE EXCEEDED, USERS ARE INVITED TO NEGOTIATE WITH THE COMPANY FOR CUSTOMIZED SOLUTIONS.

Installation, Use, and Adjustment

Pre-installation Preparation

1. Ensure all components are meticulously dust-free, wiping clean the insulating porcelain bottle surfaces for optimal performance.
2. Thoroughly scrub the wiring surface of the ground screw to ensure connectivity.
3. Apply a protective layer of industrial Vaseline to all rotating parts and contact interfaces for enhanced durability.
4. Diligently inspect the contact surfaces, adjusting the compression spring height to align contact pressure with standards outlined in Table II.
5. This switch is exclusively crafted for hoisting operations, designed to integrate seamlessly with transformers along the line.
6. With a rated current spanning 200-400 ampere hours, typically deploying three mounting holes, while 600-1000A configurations also utilize this setup.

Annual Maintenance Checklist:
Regularly eliminate dirt from conductive parts, contact surfaces, and the surface of insulating porcelain bottles to maintain optimal function.

Conduct a thorough inspection for any damage, specifically focusing on the integrity of the insulating porcelain bottles for cracks and defects.

Ensure the conductive part's contact surface remains pristine and effective.
