Product Description

Product Description

Allow us to present the state-of-the-art (H)GWBEB type outdoor high-voltage isolation switch, also known as an isolation disconnect switch. This marvel of engineering is impeccably crafted for seamless operation on high voltage power transmission and distribution lines, specifically rated at 10(12, 15, 24)kV. With a focus on maximizing safety and reliability, this advanced switch excels in opening and closing single-phase or three-phase circuits under voltage conditions, all without carrying any load.

This switch is an engineering masterpiece designed for single-phase use within three-phase systems. It shines through with its simplicity, cost-effectiveness, and straightforward operation. Remarkably versatile, it accommodates rated currents ranging from 200 to 1250 amps, including 200, 400, 600, 800, 1000, and 1250. The switch features a robust base, durable post insulators, premium conductive components, and an advanced mechanical section. Its innovative gate knife structure optimizes circuit operations, with each phase equipped with two conductive blades. To ensure optimal contact pressure, adjustable external compression springs are placed on both sides. The switch operation is seamlessly handled using an insulated hook stick, complemented by a self-locking device for enhanced security.

Working Environment:

Flawlessly engineered to perform at altitudes up to 1000 meters;

Expertly crafted to withstand ambient temperatures: maximum up to +40°C; minimum as low as -30°C;

Designed to ensure performance in outdoor wind speeds not exceeding 35 meters/second;

Built with enduring durability to withstand seismic activities up to 8 degrees, ideal for installation sites with minimal severe vibrations.

For optimal functionality, the installation site must be devoid of gases, chemical deposits, salt mist, dust, or any explosive or corrosive mediums that could adversely affect the switch's insulation and conductivity.

Note:

SHOULD CONDITIONS EXCEED THE NORMAL PARAMETERS, USERS ARE ADVISED TO CONSULT WITH THE COMPANY FOR OPTIMAL SOLUTIONS.

Installation, Use and Adjustment

Pre-installation work

1. Maximize performance by removing all dust and dirt from components. Maintain the porcelain insulating bottle's integrity by carefully cleaning its surface.
2. Ensure optimal electrical contact by thoroughly cleaning the wiring surface of the ground screw.
3. Apply a protective industrial Vaseline layer on all rotating parts and contact areas to ensure smooth operation.
4. Diligently inspect the contact surface. Adjust the compression spring height to meet the specifications detailed in Table II.
5. This switch is exclusively engineered for hoisting applications and is designed to integrate seamlessly with transformers on the line.
6. Supporting rated currents from 200 to 400 amperes typically requires three mounting holes, while the 600-1000A configurations also utilize three mounting holes for optimal stability.

Ensure enduring performance by conducting annual inspections on the following parts:
Carefully clean any dirt from conductive parts, contact surfaces, and the porcelain insulating bottle to maintain functionality.

Inspect all components for any potential damage, paying particular attention to any signs of damage or cracks in the porcelain insulating bottle.

Verify that the conductive part's contact surface remains in excellent condition to guarantee efficient operation.
