Product Description
General
Introducing the (H)GW9 outdoor high voltage switch equipment, a pinnacle of engineering excellence designed to operate seamlessly in single-phase AC 50Hz power systems. Crafted for environments where the rated voltage hits the 10kV mark, this equipment is adept at managing power supply transitions under voltage conditions, with no load present. Its design features include an isolated hook rod, ensuring smooth and reliable operation.
Service conditions
1. The installation altitude requirement is optimal up to 1000 meters, ensuring the equipment operates efficiently within this range.
2. Experience superior performance under diverse temperature conditions: Max temperature reaches +40ºC, while minimum extends to -30ºC, and even as low as -40ºC in Paramos.
3. Engineered to withstand wind pressures up to 700Pa, equivalent to wind speeds of 34m/s, ensuring reliability under high wind conditions.
4. Built to endure seismic activities, this equipment holds steadfast with an earthquake intensity threshold of up to 8 degrees.
5. Engineered for stability, the system functions optimally without being subjected to frequent, harsh vibrations.
6. For ordinary isolators, ensure the installation site remains free from gas, smoke, chemical deposits, salt-spray fog, and dust. Avoidance of these elements is crucial to maintain the isolator's insulation and conduction capabilities and prevent exposure to explosive and corrosive environments.
7. Specially designed pollution-proof isolators cater to areas with severe contamination, providing safety from flammable and explosive hazards, enhancing the system's enduring performance.
Scope
Type IST off-load switches boast resiliency, ideal for tropical zones. They perform admirably in environments where temperatures soar to 40 degrees Centigrade, with an average of 28 degrees, coupled with high humidity and heavy rainfalls. They showcase exceptional functionality up to 1800 meters above sea level.
Electrical System
Designed for robustness, the Type IST off-load isolator switches maintain uninterrupted operation on a 3-phase, 3-wire system with voltage capabilities ranging between 11kV and 36kV at 50/60Hz. The star-point of the source-point transformer is securely earthed via an Arc Suppression Coil or an Earthing Resistor, ensuring safe and stable power management.
Standards
The Type IST off-load isolator switches are meticulously crafted to adhere to stringent standards, incorporating all contemporary amendments, ensuring consistency and quality.
