Introducing the revolutionary (H)GWBEB type outdoor high-voltage isolation switch, also known as the isolation disconnect switch. This state-of-the-art device is meticulously engineered to elevate the performance of 10(12, 15, 24)kV high voltage power transmission and distribution lines. Expertly crafted for seamless operation, it masterfully handles the opening and closing of single-phase or three-phase circuits with unparalleled precision. Even under voltage, it operates efficiently without any load, assuring maximum safety and unmatched reliability in every use.
Behold the marvel of engineering excellence: a switch designed for single-phase usage within three-phase line systems. Distinguished by its straightforward design, incredible cost-effectiveness, and ease of use, this switch is versatile enough to accommodate rated currents of 200, 400, 600, 800, 1000, and 1250 amps. It features a robust base, durable post insulators, premium conductive parts, and an efficient mechanical section. The innovative gate knife structure enhances circuit operations, with dual conductive blades in each phase's gate knife. External compression springs on either side ensure optimal contact pressure, adjustable via spring height modification. With operations made simple through an insulated hook stick, the switch includes a reliable self-locking device for enhanced security.
Working Environment:
Meticulously designed to deliver exceptional performance at altitudes not exceeding 1000 meters;
Expertly crafted to withstand a wide range of ambient temperatures: from a maximum of +40°C to a minimum of -30°C;
Engineered to maintain impeccable performance even with outdoor wind speeds reaching up to 35 meters/second;
Durably built to withstand seismic intensities up to 8 degrees; ideal for installation in areas with minimal severe vibrations.
For the switch's optimal performance, the installation site should be free from gases, chemical deposits, salt mist, dust, dirt, or any other explosive or corrosive mediums that could negatively affect its insulation and conductivity.
Note:
WHEN CONDITIONS SURPASS THE SPECIFIED NORMAL USE PARAMETERS, USERS ARE STRONGLY ENCOURAGED TO CONSULT WITH THE COMPANY FOR TAILORED OPTIMAL SOLUTIONS.
Installation, Use and Adjustment
Pre-installation work
Ensure longevity by conducting annual inspections of these critical components:
Scrupulously remove any dirt from conductive parts, contact surfaces, and the insulating porcelain bottle's surface to maintain seamless functionality.
Inspect all components for potential damage, paying particular attention to the insulating porcelain bottle for any signs of damage or cracks.
Ensure that the contact surface of the conductive part is in pristine condition to guarantee efficient operation.
