Product Description

Product Description

Introducing the (H)GWBEB Type Outdoor High-Voltage Isolation Switch, a cutting-edge solution specifically crafted for deployment on 10(12, 15, 24)kV high voltage power transmission and distribution lines. This state-of-the-art isolation disconnect switch is engineered to efficiently open and close single-phase or three-phase circuits, ensuring safety even with voltage present, but devoid of load. Experience the perfect blend of reliability and innovation with our product.

This switch is meticulously designed for single-phase operations within three-phase line systems, boasting a simple yet robust structure that offers cost-efficiency and user-friendliness. With available rated currents of 200, 400, 600, 800, 1000, and 1250 amps, it embodies versatility and adaptability for varying needs. Composed of a sturdy base, durable post insulators, high-conductivity parts, and a mechanical section, our switch employs a sophisticated gate knife structure for seamless circuit operations. Each phase's gate knife is equipped with dual conductive blades, further enhanced by external compression springs for optimal contact pressure, easily adjustable in height. Operated effortlessly with an insulated hook stick, it also features a secure self-locking mechanism for added safety.

Working Environment:

Operates perfectly at altitudes not exceeding 1000 meters; ideal for diverse geographical settings.

Designed to withstand ambient temperatures ranging from a maximum of +40°C to a minimum of -30°C, ensuring reliable performance in extreme climates.

Capable of withstanding outdoor wind speeds up to 35 meters/second, reflecting its robust and resilient design.

Ensures seamless performance in environments with seismic intensity not exceeding 8 degrees, provided the installation site is free from frequent severe vibrations.

Installation sites must be devoid of gases, chemical deposits, salt mist, dust, dirt, or other explosive or corrosive mediums that could severely compromise the switch's insulation and conductivity.

Note:

In scenarios where the aforementioned normal use conditions are exceeded, users are encouraged to negotiate with Beierbian Group Co., Ltd for tailored solutions.

Installation, Use and Adjustment

Pre-installation work

1. Ensure the removal of all dust and dirt from the components, and meticulously clean the surface of the insulating porcelain bottle to guarantee optimal performance.
2. Thoroughly scrub the wiring surface of the ground screw to maintain impeccable connectivity.
3. Apply a protective layer of industrial Vaseline to the rotating parts and contact areas to ensure smooth operation and longevity.
4. Assess the contact surface and adjust the height of the compression spring to ensure that the contact pressure complies with Table II standards, optimizing switch performance.
5. This switch is exclusively designed for hoisting use and is intended to be used in conjunction with the transformer on the line, showcasing its specialized application.
6. The rated current for this switch ranges from 200 to 400 ampere hours, typically utilizing three mounting holes. For 600-1000A applications, three mounting holes are employed, highlighting its adaptable installation design.

Conduct an annual inspection of the following switch components:
Diligently remove dirt from conductive parts, contact surfaces, and the insulating porcelain bottle to uphold optimal functionality and performance.

Inspect all components for any damage, with particular attention to detecting any damage or cracks in the insulating porcelain bottle, ensuring safety and integrity.

Verify the quality of the contact surface of the conductive parts to maintain excellent electrical connectivity and reliability.
