Product Description
General Overview
Introducing the (H)GW9 outdoor high voltage switch equipment, designed for single-phase AC 50Hz applications. This remarkable product is aptly suited for power systems with a rated voltage of 10kV, allowing seamless making or breaking of power supplies in voltage conditions without load. It features a robust isolated hook rod for operational excellence.
Service Conditions
1. The installation altitude should not surpass 1000 meters, ensuring optimal performance.
2. Ambient air temperature range: Maximum of +40ºC and a Minimum of -30ºC, with Paramos areas extending to -40ºC for versatile utility.
3. Designed to withstand wind pressures up to 700Pa, equivalent to impressive wind speeds of 34m/s, ensuring reliability in blustery conditions.
4. Built to endure earthquake intensities up to 8 degrees, providing steadfast operational integrity.
5. Engineered for environments free from frequent, intense vibrations, ensuring stability.
6. Ordinary type isolator installations should be located away from gas, smoke, chemical deposits, salt-spray fog, dust, and other harmful agents that could compromise the insulation and conduction capabilities.
7. Pollution-proof type isolators are ideal for severely contaminated areas, though they should remain clear of explosive or fire-inducing materials.
Scope of Application
Type IST off-load switches are meticulously engineered for tropical zones, supporting a maximum ambient temperature of 40°C and an average of 28°C, even amidst high humidity and significant rainfall. They are optimally designed for altitudes reaching up to 1800 meters above sea level.
Electrical System Compatibility
The Type IST off-load isolator switch is crafted for continuous operation within 3-phase, 3-wire systems ranging from 11 to 36kV at 50/60Hz. Moreover, the star-point of the source-point transformer is securely earthed using an Arc Suppression Coil or an Earthing Resistor for enhanced safety.
Standards Compliance
Type IST off-load isolator switches adhere to stringent standards with all the latest amendments to ensure superior quality and reliability;
IEC62271-102:2003: High-voltage alternating-current disconnectors and earthing switches
IEC60129:1984: Alternating current disconnectors and earth switches
