Product Description
General
Introducing the (H)GW9 outdoor high voltage switch equipment, an exceptional single-phase AC 50Hz device. Designed for power systems with a rated voltage of 10kV, this product is perfect for managing power supply under voltage and no-load conditions with remarkable efficiency. It features an innovative isolated hook rod for smooth operation of the isolator.
Service Conditions
1. Ensures optimal performance at altitudes up to 1000 meters above sea level.
2. Operates efficiently in a wide range of temperatures: Maximum of +40ºC and Minimum of -30ºC, with Paramos reaching -40ºC for extreme resilience.
3. Designed to withstand wind pressures up to 700Pa, equating to a wind speed of 34m/s.
4. Engineered to endure earthquake intensities up to 8 degrees, providing robust reliability.
5. Crafted for environments with minimal and infrequent violent vibrations.
6. The ordinary type isolator installation site should be well-protected from gas, smoke, chemical deposits, salt-spray fog, dust, and other harmful explosive and corrosive substances that could compromise insulation and conduction capabilities.
7. The pollution-proof type isolator is tailored for severely contaminated areas, yet it must remain free of explosive and fire-inducing substances.
Scope
Type IST off-load switches are expertly crafted for tropical zones, thriving in a maximum ambient temperature of approximately 40°C and an average temperature near 28°C, complemented by high humidity and heavy rainfall. Recommended for operational altitudes up to 1800 meters above sea level.
Electrical System
The Type IST off-load isolator switch is engineered for continuous operation within a 3-phase 3-wire system; compatible with 11, 15, 22, 24, 27, and 33, 36kV, 50/60Hz distribution systems. The system's star-point transformer is securely earthed using an Arc Suppression Coil or Earthing Resistor.
