Product Description
General
Introducing the (H)GW9 outdoor high voltage switch equipment, meticulously crafted for single-phase AC 50Hz systems. Ideally suited for power infrastructures operating with a rated voltage of 10kV, this exceptional product enables seamless power supply transitions under voltage without load conditions. Equipped with an isolated hook rod, it ensures reliable operation at all times.
Service conditions
1. Ideally positioned at altitudes not surpassing 1000 meters, ensuring optimal performance.
2. Withstands ambient air temperatures ranging from a sweltering +40ºC to a brisk -30ºC, and even as low as -40ºC in Paramos.
3. Capable of enduring wind pressures up to a robust 700Pa, which corresponds to wind speeds reaching 34 meters per second.
4. Built to withstand earthquakes with intensities up to 8 degrees on the Richter scale, offering steadfast stability.
5. Engineered for environments where intense and frequent vibrations are nonexistent, affirming reliable operations.
6. To maintain peak performance, ensure the installation site for ordinary type isolators is free from gas emissions, smoke, chemical residues, salt-spray fog, dust, and any explosive or corrosive substances that might compromise insulation and conduction.
7. The pollution-proof type isolator is specifically designed for heavily contaminated conductive areas, ensuring safety by avoiding explosive materials and fire hazards.
Scope
The Type IST off-load switches are engineered for tropical zones, thriving in maximum temperatures of 40 degrees Centigrade and averaging 28 degrees Centigrade with high humidity and copious rainfall. They are ideally suited for operations at altitudes reaching 1800 meters above sea level.
Electrical System
Crafted for excellence, the Type IST off-load isolator switches operate continuously on a robust 3-phase 3-wire system ranging from 11kV to 36kV, compatible with both 50Hz and 60Hz distribution networks. The star-point of the source-point transformer is earthed via an Arc Suppression Coil or an Earthing Resistor, ensuring dependable performance.
Standards
The Type IST off-load isolator switches adhere strictly to the pertinent requirements of the following standards, incorporating all current amendments for uncompromised safety and efficiency;
IEC62271-102:2003 : This standard governs high-voltage alternating-current disconnectors and earthing switches, ensuring reliable performance.
