Product Description
General
The (H)GW9 Outdoor High Voltage Switch Equipment stands out in its class, designed specifically for single phase AC systems operating at 50Hz. It excels in power systems with a rated voltage of 10kV, mastering the art of making or breaking power supplies under conditions of voltage without load. The innovative design incorporates an isolated hook rod for seamless operation, ensuring both efficiency and safety.
Service Conditions
1. This product is perfectly suited for environments where the altitude does not exceed 1000m, offering reliable performance at this elevation.
2. The product boasts resilience in a wide range of temperatures, withstanding ambient air temperatures from a chilly -30ºC to a warm +40ºC (Paramos minimum of -40ºC), ensuring versatility across diverse climates.
3. Designed to endure, it can handle wind pressures not exceeding 700Pa, equating to wind speeds up to 34m/s, providing robust performance in gusty conditions.
4. Built to last, it stands strong against seismic activities, with a capacity to withstand earthquake intensities up to 8 degrees.
5. Engineered for stability, it maintains functionality without frequent or violent vibrations, ensuring consistent operation.
6. The installation site for the ordinary type isolator should be devoid of corrosive elements such as gas, smoke, chemical deposits, salt-spray fog, and dust, as well as explosive materials, ensuring optimal insulation and conduction capabilities.
7. For areas plagued by severe pollution, the pollution-proof type isolator is your go-to, though it requires an environment free of explosive and fire-inducing substances.
Scope
Type IST off-load switches are crafted for excellence in tropical zones, thriving in ambient temperatures peaking at 40 degrees Centigrade, coupled with an average of approximately 28 degrees Centigrade. They excel in high humidity and heavy rainfall, with an optimal operational altitude of up to 1800 meters above sea level.
Electrical System
Type IST off-load isolator switches are the epitome of reliability, designed for continuous operation in 3-phase, 3-wire distribution systems ranging from 11kV to 36kV at 50/60Hz. The source-point transformer's star-point is earthed via an Arc Suppression Coil or Earthing Resistor, ensuring top-tier safety and functionality.
Standards
Type IST off-load isolator switches meet and exceed the rigorous standards set by the industry, ensuring compliance with all relevant requirements and current amendments.
IEC62271-102:2003: A benchmark for high-voltage alternating-current disconnectors and earthing switches, solidifying its status as a leader in safety and performance.
