Product Description
General
Introducing the (H)GW9 outdoor high voltage switch equipment, a state-of-the-art solution for single-phase AC 50Hz systems. This exceptional product is engineered for power systems with a rated voltage of 10kV, expertly designed to facilitate the crucial task of making or breaking power supply safely in situations of voltage presence but no load. Its advanced isolator mechanism is operated by an isolated hook rod, ensuring optimal efficiency and reliability.
Service Conditions
1. Exceptional high-altitude performance, suitable for locations up to 1000 meters above sea level.
2. Engineered for resilience, the equipment is designed to withstand ambient air temperatures with a maximum of +40ºC and a minimum of -30ºC, extending further to -40ºC in Paramos.
3. Robust against natural forces, it operates flawlessly under wind pressures up to 700Pa, equivalent to facing wind speeds up to 34m/s.
4. Seismically secure, the equipment can endure earthquake intensities up to 8 degrees, ensuring steadfast performance.
5. Designed to operate continuously without being affected by frequent or intense vibrations, guaranteeing stability.
6. For optimal performance, install the ordinary type isolator in environments free from gas, smoke, chemical deposits, salt-spray fog, dust, or any other elements that could significantly impair its insulation and conduction capabilities.
7. The pollution-proof type isolator is specially equipped for operation in heavily polluted areas; however, it must be free from explosive or flammable substances.
Scope
Type IST off-load switches are meticulously crafted for tropical climates, handling maximum ambient temperatures of around 40 degrees Celsius with ease and averaging around 28 degrees Celsius in conditions of high humidity and substantial rainfall. These switches are ideal for operational altitudes reaching up to 1800 meters above sea level.
Electrical System
Designed for robust and continuous performance, the Type IST off-load isolator switch operates flawlessly on a 3-phase 3-wire system ranging from 11 to 36kV at 50/60Hz. Engineered with the star-point of the transformer earthed through an Arc Suppression Coil or Earthing Resistor, it ensures unparalleled electrical integrity.
Standards
Type IST off-load isolator switches are manufactured to exceed the stringent requirements of the following industry standards, alongside all current amendments, ensuring unmatched quality and reliability;
IEC62271-102:2003: Focused on high-voltage alternating-current disconnectors and earthing switches, ensuring safety and efficiency.
IEC60129:1984: Pertains to alternating current disconnectors and earth switches, setting benchmark criteria for reliability.
IEC 60265-1:1998: Dedicated to high voltage switches - Part 1, covering switches for rated voltages above 1kV and under 52kV, ensuring precision in specification.
IEC 60694: 1996: Outlines common specifications for high-voltage switchgear and controlgear standards, offering comprehensive coverage for diverse applications.
IEC 60815:1986: A guiding document for selecting insulators under polluted conditions, a crucial aspect for maintaining performance integrity.
BS EN ISO 1461: Sets the standard for hot dip galvanized coatings on fabricated iron and steel articles, backed by rigorous specifications and test methods to ensure long-lasting durability.
