Product Description
General
Introducing our high-performance (H)GW9 outdoor high voltage switch equipment, crafted for excellence in single-phase AC 50Hz systems. This advanced product is tailored for power systems with a rated voltage of 10kV, expertly designed to seamlessly make or break power supply under conditions of voltage without load. The isolator is ingeniously operated via an isolated hook rod, ensuring precision and safety.
Service conditions
1. Suitable for altitudes up to 1000m, ensuring optimal performance even in elevated regions.
2. Designed to withstand ambient temperatures ranging from a scorching +40ºC to a chilling -30ºC, withstanding even harsher conditions down to -40ºC in extreme environments.
3. Engineered to endure wind pressures up to 700Pa, corresponding to gusts reaching 34m/s, thus maintaining stability in strong winds.
4. Built to withstand earthquake intensities up to 8 degrees, offering resilience during seismic activities.
5. Ideal for environments free from frequent and intense vibrations, ensuring longevity and reliability.
6. Ordinary type isolators are best installed away from harmful gases, smoke, chemical deposits, salt-spray fog, dust, and other explosive or corrosive agents that could compromise insulation and conduction performance.
7. Pollution-proof isolators are perfect for areas with severe contamination, barring explosive substances and fire-inducing conditions.
Scope
Engineered for the tropical zone, Type IST off-load switches thrive in maximum ambient temperatures of 40°C and average temperatures around 28°C, amidst high humidity and heavy rainfall. Optimal performance is assured up to altitudes of 1800 meters above sea level.
Electrical System
Type IST off-load isolator switches are meticulously designed for continuous operation within a 3-phase 3-wire system at 11, 15, 22, 24, 27, and 33, 36kV, 50/60Hz. The system features a star-point transformer earthed through an Arc Suppression Coil or Earthing Resistor, ensuring safety and reliability.
Standards
Type IST off-load isolator switches meet and exceed the stringent requirements of the following standards, incorporating all the latest amendments.
IEC62271-102:2003: High-voltage alternating-current disconnectors and earthing switches, ensuring compliance and superior quality.
IEC60129:1984: Alternating current disconnectors and earth switches, a testament to our commitment to excellence.
IEC 60265-1:1998: High voltage switches - Part 1: Switches for rated
voltage above 1kV and less than 52kV, showcasing our adherence to industry standards.
IEC 60694: 1996: Common specifications for high-voltage switchgear and
controlgear standards, ensuring reliability across all our products.
