2. Operates flawlessly in ambient air temperatures ranging from a chilly -40ºC in Paramos to a warm +40ºC, accommodating diverse environmental conditions.
3. Withstands wind pressures up to 700Pa, equating to robust 34m/s wind speeds, guaranteeing steadfast resilience.
4. Built to endure earthquake intensities of up to 8 degrees, offering steadfast stability in seismic zones.
5. Crafted for environments free from frequent violent vibrations, ensuring consistent operational integrity.
6. Installation should be in areas devoid of gas, smoke, chemical deposition, salt-spray fog, dust, and other explosive or corrosive substances that severely affect insulation and conduction capabilities.
7. Pollution-proof type isolators are suited for severely contaminated areas, provided there are no explosive materials or fire-inducing substances.
Scope
Type IST off-load switches are meticulously crafted for tropical zones, enduring ambient temperatures soaring to 40 degrees Centigrade, while maintaining an average of 28 degrees Centigrade amidst high humidity and torrential rainfall. Operates optimally at altitudes up to 1800 meters above sea level.
Electrical System
Engineered for high-performance, Type IST off-load isolator switches function seamlessly across a 3-phase 3-wire 11, 15, 22, 24, 27, 33, and 36kV, 50/60Hz distribution system. The system's star-point transformer is earthed via an Arc Suppression Coil or Earthing Resistor.
