Product Description



General
Introducing the advanced (H)GW9 outdoor high voltage switch equipment tailored for single-phase AC 50Hz operations. This exceptional product is meticulously engineered for power systems with a rated voltage of 10kV, providing seamless power supply connectivity under no-load voltage conditions. Its design incorporates an innovative isolated hook rod mechanism for efficient operation.
Service conditions
1. Designed for locations where the altitude does not exceed 1000 meters, ensuring optimal performance.
2. Capable of withstanding environmental extremes: with maximum ambient temperatures reaching +40ºC, minimum temperatures of -30ºC, and even down to -40ºC in plateau regions.
3. With resilience against wind pressures up to 700Pa, equivalent to a formidable 34m/s wind speed.
4. Engineered to endure earthquake intensities up to 8 degrees, ensuring safety and stability.
5. Ideally suited for installations where frequent or intense vibrations are not present, preserving longevity.
6. For ordinary type isolators, installation away from harmful substances such as gas, smoke, chemical deposits, salt-spray fog, and dust is crucial to maintain insulation and conduction efficiency.
7. Designed for polluted environments, our pollution-proof isolator excels in areas with severe contamination, but it's crucial to avoid explosive or fire-inducing materials.
Scope
The Type IST off-load switches are expertly crafted for tropical regions, tolerating a maximum ambient temperature of about 40°C and an average of 28°C, even amidst high humidity and substantial rainfall. Perfectly operational up to an altitude of 1800 meters above sea level.
Electrical System
Type IST off-load isolator switches are meticulously designed for uninterrupted use within 3-phase 3-wire systems ranging from 11kV to 36kV, 50/60Hz. The source-point transformer's star-point is reliably earthed through an Arc Suppression Coil or Earthing Resistor.
Standards
The Type IST off-load isolator switches adhere to stringent standards, incorporating all pertinent amendments to provide unmatched reliability:
IEC62271-102:2003: High-voltage alternating-current disconnectors and earthing switches, ensuring high performance.
IEC60129:1984: High reliability in alternating current disconnectors and earth switches.
IEC 60265-1:1998: Focused on high voltage switches for rated voltages above 1kV and less than 52kV.
