Introducing the (H)GWBEB type outdoor high-voltage isolator switch, a pinnacle of cutting-edge engineering, designed to efficiently manage 10(12, 15, 24)kV power transmission and distribution lines. This exceptional isolation disconnect switch facilitates seamless operations in both single-phase and three-phase circuits, ensuring an effective isolation process even under voltage. Experience the perfect solution for your high-voltage circuit management needs.
Tailored for single-phase applications in three-phase systems, this sophisticated switch stands out with its straightforward design, remarkable affordability, and user-friendly operation. It supports a range of rated currents: 200, 400, 600, 800, 1000, and 1250 amps, providing flexibility and adaptability. Composed of a robust base, resilient post insulators, reliable conductive parts, and a precision-engineered mechanical section, it features an innovative gate knife structure for efficient circuit control. Each phase's gate knife utilizes dual conductive blades supported by external compression springs, allowing for precise contact pressure adjustments through spring height modification. This intuitive device is operated using an insulated hook stick, complemented by a secure self-locking mechanism for optimal performance.
Working Environment:
Recommended installation at altitudes not exceeding 1000 meters for optimal performance;
Temperature tolerance ranges from a maximum of +40°C to a resilient minimum of -30°C, ensuring robust functionality in diverse climates;
Engineered to withstand outdoor wind speeds of up to 35 meters/second, guaranteeing reliability in challenging weather conditions;
Built to endure seismic intensities up to 8 degrees, this switch is crafted for environments free from frequent severe vibrations, ensuring stable and consistent operation.
The ideal installation environment should be devoid of gases, chemical residues, salt mist, dust, dirt, or other explosive or corrosive elements that could compromise the switch's exceptional insulation and conductivity.
Note:
WHEN STANDARD USAGE CONDITIONS ARE EXCEEDED, CUSTOMIZED SOLUTIONS CAN BE DISCUSSED WITH THE COMPANY TO ACCOMMODATE SPECIFIC REQUIREMENTS.
Installation, Use and Adjustment
Pre-installation work
Annually perform a comprehensive check on the switch's components to ensure sustained operational excellence:
Thoroughly cleanse dirt from conductive parts, contact surfaces, and the insulating porcelain bottles, maintaining pristine conditions.
Conduct a meticulous inspection for any damage, prioritizing the assessment of insulating porcelain bottles for potential flaws.
Ensure the contact surface of each conductive part remains in impeccable condition, reinforcing reliability and performance.
