Product Description
General
Introducing our innovative (H)GW9 outdoor high voltage switch equipment, designed specifically for single-phase AC systems operating at 50Hz. This versatile product is expertly crafted to serve power systems with a rated voltage of 10kV, enabling the seamless connection or disconnection of power supply in situations involving voltage without load. The isolator is thoughtfully engineered with an isolated hook rod for safe and efficient operation.
Service conditions
1. Experience unparalleled performance at altitudes not exceeding 1000 meters.
2. Enjoy reliable operation in ambient air temperatures ranging from a crisp -30ºC to a sweltering +40ºC, and up to -40ºC in Paramos regions.
3. Designed to withstand wind pressures up to 700Pa, corresponding to an impressive wind speed of 34m/s.
4. Built to endure earthquake intensities up to 8 degrees, ensuring robust performance in challenging environments.
5. Engineered for stability, the device is suited for environments free from frequent and violent vibrations.
6. The ordinary type isolator is perfect for installation sites free from harmful gas, smoke, chemical deposits, salt-spray fog, dust, and other explosive or corrosive elements that could affect its insulating and conducting capabilities.
7. Our pollution-proof type isolator excels in severely contaminated areas, provided there are no explosive materials or fire-inducing elements present.
Scope
Type IST off-load switches are expertly crafted for tropical zones, tolerating maximum ambient temperatures up to 40°C and averaging around 28°C, withstanding high humidity and heavy rainfall. Optimal performance is maintained at altitudes up to 1800 meters above sea level.
Electrical System
The Type IST off-load isolator switch is meticulously engineered for continuous operation on 3-phase, 3-wire distribution systems ranging from 11 to 36kV at 50/60Hz, with the star-point of the source-point transformer securely earthed via an Arc Suppression Coil or Earthing Resistor.
Standards
Our Type IST off-load isolator switch meets and exceeds the stringent requirements of the following standards, including all current amendments:
IEC62271-102:2003 :High-voltage alternating-current disconnectors and earthing switches.
IEC60129:1984 :Alternating current disconnectors and earth switches.
