Product Description
General
Introducing the (H)GW9 outdoor high voltage switch equipment, operating efficiently with single-phase AC 50Hz. Perfectly crafted for power systems with a rated voltage of 10kV, this equipment is ideal for making or breaking power supply under voltage conditions without load. Its innovative design incorporates an isolated hook rod for seamless operation.
Service conditions
1. Designed for altitudes not exceeding 1000m, ensuring robust performance and reliability.
2. Masterfully crafted to withstand ambient air temperatures ranging from a scorching +40ºC to a chilling -30ºC, and even down to -40ºC in Paramos areas.
3. Engineered to endure wind pressures up to 700Pa, equivalent to a formidable wind speed of 34m/s.
4. Constructed to perform with unwavering stability, even in earthquake intensities not exceeding 8 degrees.
5. Designed for environments free from frequent and violent vibrations, ensuring reliable performance.
6. To maintain optimal functionality, the installation site for ordinary isolators should be free from gas, smoke, chemical deposits, salt-spray fog, dust, and other explosive and corrosive substances that could compromise insulation and conduction capabilities.
7. Our pollution-proof type isolators excel in severe, filthy conduction areas, though they must remain free of explosive elements or fire-inducing materials.
Scope
The Type IST off-load switches are expertly designed for tropical zones, thriving in maximum ambient temperatures of approximately 40 degrees Centigrade and an average of 28 degrees Centigrade, while withstanding high humidity and heavy rainfall. Their preferred operational altitude extends up to 1800 m above sea level, ensuring versatility and durability.
Electrical System
The Type IST off-load isolator switches are meticulously engineered for continuous operation on 3-phase 3-wire systems of 11, 15, 22, 24, 27, 33, and 36kV at 50/60Hz. These systems feature a star-point of the source-point transformer earthed through an Arc Suppression Coil or Earthing Resistor, ensuring dependable performance.
