Product Description
General
Introducing the (H)GW9 Outdoor High Voltage Switch Equipment, designed for seamless operation in single-phase AC systems at 50Hz frequency. Engineered for power systems with a rated voltage of 10kV, this product efficiently manages the connection and disconnection of power supplies, specifically under voltage conditions and no load scenarios. The equipment incorporates an advanced isolated hook rod for precise and safe operation.
Service conditions
1. The equipment is effective for installations where the altitude does not exceed 1000 meters, ensuring optimal performance.
2. Designed to withstand ambient air temperatures ranging from a maximum of +40ºC to a minimum of -30ºC, with an exceptional paramos tolerance of -40ºC.
3. Built to endure wind pressures up to 700Pa, corresponding to dynamic wind speeds reaching 34 meters per second.
4. Resilient against seismic activities, this product maintains integrity and performance up to an earthquake intensity of 8 degrees.
5. Ideal for environments devoid of frequent or severe vibrations, ensuring device longevity and reliability.
6. For optimal functionality, install ordinary type isolators away from harmful gases, chemical smokes, salt-spray fog, dust, and any corrosive or explosive substances that compromise insulation and conduction capabilities.
7. The pollution-proof type isolator is perfect for severely polluted areas, though it must remain clear of any explosive materials or fire-inducing substances.
Scope
Crafted for tropical zones, Type IST Off-load Switches excel in environments with a maximum ambient temperature of 40 degrees Centigrade and an average of 28 degrees Centigrade, thriving amidst high humidity and heavy rainfall. An operational altitude of up to 1800 meters above sea level is recommended for optimal performance.
Electrical System
Type IST Off-load Isolator Switches are meticulously engineered for continuous function within 3-phase 3-wire systems ranging from 11kV to 36kV at 50/60Hz. Designed with safety in mind, the star-point of the source-point transformer is securely earthed via an Arc Suppression Coil or Earthing Resistor.
Standards
Type IST Off-load Isolator Switches meet the rigorous criteria of the following standards, incorporating all current amendments to ensure state-of-the-art compliance;
IEC62271-102:2003 : High-voltage alternating-current disconnectors and earthing switches
