Product Description

Product Description

Introducing the (H)GWBEB type outdoor high-voltage isolation switch, a marvel of electrical engineering designed to enhance the functionality of your 10(12, 15, 24)kV high voltage power transmission and distribution lines. This sophisticated switch, also known as an isolation disconnect switch, is adept at opening and closing single-phase or three-phase circuits with voltage present but without load. Experience unparalleled efficiency in your outdoor electrical systems!

This switch is engineered for single-phase applications within three-phase line systems, renowned for its uncomplicated design, affordability, and user-friendliness. Available in a variety of rated currents from 200 to 1250 amps, these switches are composed of a base, robust post insulators, conductive elements, and a mechanical section. Featuring a gate knife structure for seamless circuit operation, each phase incorporates two conductive blades supported by external compression springs on both sides. Fine-tuning the spring height ensures optimal contact pressure for the gate knife's operation. Designed for operation with an insulated hook stick, it also boasts a reliable self-locking feature.

Working Environment:

Capable of operating at altitudes up to 1000 meters;

Handles a wide ambient temperature range, from a maximum of +40°C to a minimum of -30°C;

Built to withstand outdoor wind speeds up to 35 meters/second;

Resilient to seismic intensities up to 8 degrees, ideally installed at locations with minimal severe vibrations.

Optimal performance is ensured when the installation site is free from gases, chemical deposits, salt mist, dust, dirt, or other explosive or corrosive substances that could compromise insulation and conductivity.

Note:

SHOULD NORMAL USE CONDITIONS EXCEED THE STATED LIMITS, USERS ARE WELCOME TO DISCUSS OPTIONS WITH THE COMPANY.

Installation, Use and Adjustment

Pre-installation work

1. Meticulously remove dust and dirt from components, ensuring the insulating porcelain bottle's surface is spotlessly clean.
2. Thoroughly clean the wiring surface of the grounding screw.
3. Apply a protective layer of industrial Vaseline to all rotating components and contact areas.
4. Inspect the contact surfaces, adjusting the compression spring height to maintain optimal contact pressure as specified in Table II.
5. Designed exclusively for hoisting applications, this switch is intended for use with transformers on the line.
6. For switches rated at 200-400 ampere hours, three mounting holes suffice. Similarly, 600-1000A installations typically use three mounting holes.

Conduct an annual inspection of these crucial switch components:
Eliminate dirt from conductive parts, contact surfaces, and insulating porcelain bottles to maintain optimal function.

Scrutinize all parts for any signs of damage, with particular focus on identifying insulation porcelain bottle cracks or damage.

Verify that the conductive part's contact surface remains in excellent condition.
