Product Description
General
Introducing the (H)GW9 Outdoor High Voltage Switch Equipment! This sophisticated single-phase AC unit operates at 50Hz and is perfect for power systems with a rated voltage of 10kV. Specifically designed to manage the make-or-break power supply operations amidst voltage variations without any load, this equipment features an innovative isolated hook rod for seamless operation. Crafted for reliability, it ensures efficient and safe functionality in various electrical systems.
Service conditions
1. Altitude should not surpass 1000 meters, ensuring optimal performance across diverse terrains.
2. Ambient air temperature ranges: Maximum: +40ºC, Minimum: -30ºC, with Paramos conditions allowing for a chilling -40ºC.
3. Withstand wind pressures up to 700Pa, equating to robust defense against wind speeds reaching 34m/s.
4. Built to endure earthquake intensities up to 8 degrees, promising stability even in seismic zones.
5. Designed to operate smoothly without the disturbance of frequent violent vibrations.
6. For ordinary isolators, installation sites must be free from gas, smoke, chemical deposits, salt-spray fog, dust, or any explosive and corrosive elements, ensuring that insulation and conduction capabilities remain uncompromised.
7. Pollution-proof isolators are suited for heavily polluted areas, provided that these zones are devoid of explosive materials or fire-inducing substances.
Scope
Type IST off-load switches are ideally suited for tropical environments, thriving in conditions with maximum temperatures up to 40°C and average temperatures around 28°C, even amidst high humidity and heavy rainfall. These switches boast a preferred operational altitude of up to 1800 meters above sea level, adapting easily to various climatic conditions.
Electrical System
These Type IST off-load isolator switches are engineered for continuous duty on a robust 3-phase, 3-wire distribution system (11 to 36kV, 50/60Hz). The star-point of the source-point transformer is reliably earthed through an Arc Suppression Coil or Earthing Resistor, ensuring secure and stable electrical connections.
Standards
The Type IST off-load isolator switch adheres rigorously to the following standards, including all current amendments, ensuring state-of-the-art compliance and excellence:
IEC62271-102:2003 - High-voltage alternating-current disconnectors and earthing switches
IEC60129:1984 - Alternating current disconnectors and earth switches
IEC 60265-1:1998 - High voltage switches - Part 1: Switches for rated
voltage above 1kV and less than 52kV
