Product Description
General
Introducing the (H)GW9 Outdoor High Voltage Switch Equipment, a single-phase AC 50Hz marvel. Specially designed for power systems boasting a rated voltage of 10kV, this equipment excels in seamlessly making or breaking power supply under specific conditions of voltage and no load. The isolator is operated using a sophisticated isolated hook rod, ensuring safety and reliability.
Service conditions
1. Operating at altitudes not exceeding 1000m, this equipment is tailored for diverse elevations.
2. It thrives in extreme temperatures with an ambient air range: Maximum of +40ºC and Minimum of -30ºC, and for colder regions, a minimum of -40ºC, ensuring flawless performance.
3. Engineered to withstand wind pressures up to 700Pa, equivalent to wind speeds of 34m/s, guaranteeing stability even in challenging weather.
4. Built to resist, it safely operates through earthquake intensities up to 8 degrees, offering peace of mind in seismic zones.
5. The equipment promises durability by performing steadily without succumbing to frequent violent vibrations.
6. For ordinary type isolators, it's vital to avoid installation near gas, smoke chemical deposition, salt-spray, dust, and other explosive or corrosive materials, as these can severely impact insulation and conduction capabilities.
7. Pollution-proof type isolators are the choice for severely filthy conduction areas, provided there are no explosive or fire-causing substances.
Scope
The versatile Type IST Off-load Switches shine in tropical zones, enduring a maximum ambient temperature of 40ºC and an average of 28ºC amidst high humidity and heavy rains. Ideally operational up to altitudes of 1800m above sea level, they adapt to challenging environments.
Electrical System
Crafted for uninterrupted performance, the Type IST Off-load Isolator Switch operates flawlessly on a 3-phase, 3-wire system of 11, 15, 22, 24, 27, and 33, 36kV, at 50/60Hz. The star-point of the source-point transformer is earthed through either an Arc Suppression Coil or an Earthing Resistor, ensuring efficiency and safety.
Standards
Type IST Off-load Isolator Switches meet the rigorous demands of the following standards, alongside all current amendments:
IEC62271-102:2003: High-voltage alternating-current disconnectors and earthing switches.
IEC60129:1984: Alternating current disconnectors and earthing switches.
