Product Description

Product Description

Introducing the (H)GWBEB type outdoor high-voltage isolation switch, also known as an isolation disconnect switch. This advanced switch is meticulously engineered for seamless integration on 10(12, 15, 24)kV high voltage power transmission and distribution lines. It is designed to efficiently open and close single-phase or three-phase circuits with voltage present but without load, ensuring optimal performance and reliability.

This exceptional switch is tailored for single-phase applications within three-phase line systems. It stands out due to its streamlined design, cost-effectiveness, and user-friendly operation. Choose from available rated currents of 200, 400, 600, 800, 1000, and 1250 amps. The switch is composed of a robust base, durable post insulators, conductive components, and a sophisticated mechanical section. The innovative gate knife structure facilitates precise opening and closing of the circuit. For each phase, the gate knife features two high-conductivity blades enhanced by external compression springs on both sides, allowing for adjustable spring height to achieve the desired contact pressure. The switch is operated with an insulated hook stick for effortless actions, and incorporates a reliable self-locking device for enhanced safety.

Working Environment:

Designed for operation at altitudes not exceeding 1000 meters;

Capable of withstanding ambient temperatures: maximum of +40°C and minimum of -30°C;

Built to endure outdoor wind speeds of up to 35 meters/second;

Seismic intensity resilience up to 8 degrees; ensuring stability at sites with minimal severe vibrations.

Installation sites must be free from gases, chemical deposits, salt mist, dust, dirt, or other explosive or corrosive media that could adversely affect the switch's insulation and conductivity.

Note:

WHEN USAGE EXCEEDS NORMAL CONDITIONS, USERS ARE ENCOURAGED TO CONSULT WITH THE COMPANY FOR SPECIFIC SOLUTIONS.

Installation, Use and Adjustment

Pre-installation work

1. Ensure all parts are free from dust and dirt, and gently clean the surfaces of the insulating porcelain bottles for optimal performance.
2. Thoroughly scrub the wiring surface of the ground screw to maintain impeccable electrical connectivity.
3. Apply a protective layer of industrial Vaseline to all rotating parts and contact areas to ensure smooth operation.
4. Inspect the contact surfaces and meticulously adjust the compression spring height so that contact pressure aligns with specifications outlined in Table II.
5. This switch is specifically designed for hoisting operations and should be used in conjunction with transformers on the line for effective performance.
6. With a rated current range of 200-400 ampere hours, generally three mounting holes are sufficient. For currents ranging 600-1000A, three mounting holes are also employed.

Conduct a comprehensive annual inspection to maintain the switch's pristine condition:
Remove any accumulation of dirt from conductive parts, contact surfaces, and the insulating porcelain bottles to preserve high efficiency.

Inspect all components for possible damage, giving special attention to the insulating porcelain bottles for signs of damage or cracks.

Verify that the contact surfaces of the conductive parts are in excellent condition to ensure uninterrupted energy flow.
