Product Description

Product Description

Introducing the (H)GWBEB type outdoor high-voltage isolation switch, a marvel of engineering innovation, commonly referred to as the isolation disconnect switch. This extraordinary piece of technology is meticulously crafted for seamless integration into 10(12, 15, 24)kV high voltage power transmission and distribution lines. Its primary function is to efficiently open and close single-phase or three-phase circuits while voltage is present, yet without load—ensuring safety and reliability in operation.

Designed specifically for single-phase applications within three-phase line systems, this switch stands out for its straightforward design, economical pricing, and user-friendliness. It boasts a variety of available rated currents, including 200, 400, 600, 800, 1000, and 1250 amps. The construction includes a robust base, durable post insulators, conductive components, and a precision-engineered mechanical section. Utilizing a gate knife structure, the switch facilitates the opening and closing of circuits. Each phase's gate knife features two conductive blades, complemented by external compression springs on both sides, with adjustable spring heights to ensure optimal contact pressure. Operation is effortlessly executed using an insulated hook stick, which controls the switch's opening and closing actions, further enhanced by a self-locking mechanism.

Working Environment:

The ideal altitude for operation should not exceed 1000 meters above sea level;

The ambient temperature is perfectly suited to a maximum of +40°C and a minimum of -30°C;

The switch can withstand outdoor wind speeds of up to 35 meters/second, ensuring durability against natural forces;

With a seismic resilience of up to 8 degrees, the installation site should be free from frequent severe vibrations, providing a stable operational environment.

The installation area must remain free of harmful gases, chemical deposits, salt mist, dust, dirt, or other explosive or corrosive substances that could significantly impair the switch's effectiveness in terms of insulation and conductivity.

Note:

SHOULD YOU ENCOUNTER CONDITIONS BEYOND THE STANDARD SPECIFICATIONS, WE ENCOURAGE USERS TO DISCUSS CUSTOM SOLUTIONS DIRECTLY WITH OUR COMPANY FOR OPTIMAL PERFORMANCE.

Installation, Use and Adjustment

Pre-installation work

1. Commence by meticulously removing any dust and dirt from all parts, paying particular attention to the insulating porcelain bottle's surface for optimal cleanliness.
2. Carefully scrub the wiring surface of the ground screw to ensure optimal electrical connectivity.
3. Apply a generous layer of industrial Vaseline to all rotating parts and contact areas to enhance the longevity and smooth operation of the switch.
4. Thoroughly inspect the contact surface and make necessary adjustments to the height of the compression spring to meet the specifications outlined in Table II, ensuring superior contact pressure.
5. This switch is explicitly designed for hoisting use, optimized for seamless cooperation with transformers along the line, ensuring efficient energy distribution.
6. The switch's rated current ranges from 200-400 ampere hours, utilizing three mounting holes typically. For higher currents, between 600-1000A, three mounting holes are also employed, ensuring robust installation.

For sustained performance, undertake an annual examination of the following switch components:
Meticulously clean dirt from conductive parts, contact surfaces, and the exterior of insulating porcelain bottles to maintain peak performance.

Conduct a comprehensive inspection of all parts for potential damage, with special focus on detecting any damage or cracks in the insulating porcelain bottle.

Assess the quality of the contact surface of the conductive part to confirm its optimal condition.
