Service conditions
1. Perfect for installations where the altitude does not exceed 1000 meters, ensuring optimal performance.
2. Capable of withstanding ambient air temperatures ranging from a chilly -30ºC to a sweltering +40ºC, with Paramos resilience down to -40ºC.
3. Built to endure wind pressures up to 700Pa, equivalent to wind speeds of 34m/s, ensuring reliability even in gusty conditions.
4. Engineered to tolerate earthquake intensities up to 8 degrees, providing robust performance in seismic areas.
5. Designed for environments without frequent, severe vibrations, guaranteeing stability and longevity.
6. Ideal for regular installation sites, it should be free from gas, smoke, chemical deposits, salt spray, fog, dust, or any explosive and corrosive substances that could impair insulation and conduction.
7. For areas prone to severe pollution, the pollution-proof type isolator is the perfect choice, though it must be free from explosive materials or fire hazards.
Scope
Type IST off-load switches are impeccably suited for tropical regions, thriving at a maximum ambient temperature of 40 degrees Centigrade and an average of 28 degrees. They endure high humidity and heavy rainfall effortlessly, with a preferred operational altitude up to 1800 meters above sea level.
Electrical System
Designed for continuous, reliable operation, the Type IST off-load isolator switch handles 3-phase 3-wire systems ranging from 11kV to 36kV at 50/60Hz. The system's star-point transformer is earthed using an Arc Suppression Coil or Earthing Resistor for enhanced safety.
