Operated with an isolated hook rod, this isolator guarantees unparalleled reliability and performance.
Service Conditions
1. Designed for altitudes up to 1000 meters, this product is built to withstand the rigors of high-altitude environments.
2. Engineered to endure extreme temperatures with an ambient air range from a blistering +40ºC to a chilling -30ºC, and down to -40ºC in Paramos.
3. Constructed to resist wind pressures up to 700Pa, correlating to a fierce wind speed of 34 meters per second.
4. Robustly designed to tolerate earthquake intensities up to 8 degrees, ensuring stability and safety.
5. Optimized for environments without frequent or severe vibrations, maintaining operational integrity.
6. The ordinary type isolator is ideally installed away from harmful gases, chemical deposits, salt-spray, smoke, and dust that adversely affect insulation and conduction capabilities.
7. Specifically, the pollution-proof type isolator thrives in severely filthy conditions, provided there are no explosive or incendiary substances present.
Scope
The IST off-load switches are expertly crafted for use in tropical zones, where the climate boasts a maximum ambient temperature of approximately 40 degrees Centigrade and averages around 28 degrees with high humidity and intense rainfall. Perfect for altitudes reaching up to 1800 meters above sea level.
Electrical System
The sophisticated IST off-load isolator switch is engineered for unyielding continuous operation on a 3-phase 3-wire system, accommodating 11, 15, 22, 24, 27, and 33, 36kV at 50/60Hz. The star-point of the source-point transformer is securely earthed via an Arc Suppression Coil or Earthing Resistor.
Standards
The IST off-load isolator switch fully complies with all pertinent standards and their current amendments, ensuring absolute reliability and safety.
IEC62271-102:2003: High-voltage alternating-current disconnectors and earthing switches, assuring top-tier quality and trusted performance.
