Product Description
General
Introducing the (H)GW9 outdoor high-voltage switch equipment, engineered for single-phase AC 50Hz applications. Perfectly crafted for power systems with a rated voltage of 10kV, it efficiently facilitates the making or breaking of power supply under no-load voltage conditions. With an innovative isolated hook rod operation, it ensures seamless functionality.
Service conditions
1. Designed to perform at altitudes up to 1000m, this equipment guarantees reliable operation in elevated regions.
2. Versatile ambient air temperature resilience: Maximum at a sizzling +40ºC, Minimum chilling at -30ºC, and a special provision for Paramos extending to -40ºC.
3. Built to withstand wind pressures up to 700Pa, equating to a formidable 34m/s wind speed.
4. Engineered to endure earthquake intensity levels of up to 8 degrees, ensuring safety during seismic events.
5. Designed for stability in environments free of frequent, violent vibrations, ensuring a steady performance.
6. The installation site for the ordinary type isolator must remain distant from harmful gases, chemical deposits, salt-spray fog, dust, and other explosive and corrosive elements that significantly impair insulation and conduction capabilities.
7. The pollution-proof type isolator is a robust solution for severely filthy areas, yet it must remain free from explosive or fire-inducing elements.
Scope
Type IST off-load switches are ideal for tropical climates, thriving in maximum ambient temperatures of around 40°C and an average of 28°C, even amidst high humidity and substantial rainfall. Optimized for altitudes up to 1800 meters above sea level.
Electrical System
The Type IST off-load isolator switch is meticulously crafted for uninterrupted operation on a 3-phase, 3-wire system, suitable for 11, 15, 22, 24, 27, 33, and 36kV at 50/60Hz distribution. Featuring the star-point of the source-point transformer earthed via an Arc Suppression Coil or Earthing Resistor, it ensures unparalleled reliability.
