Product Description
General
Introducing the robust and reliable (H)GW9 outdoor high voltage switchgear, meticulously engineered for single-phase AC 50Hz systems. This advanced product is perfectly suited for power systems with a rated voltage of 10kV, ensuring efficient power supply control under voltage conditions without load. Operate with ease using the isolated hook rod mechanism for optimal safety and precision.
Service conditions
1. Designed to perform seamlessly at altitudes up to 1000 meters.
2. Capable of withstanding a wide range of ambient air temperatures, with a maximum of +40ºC and a minimum down to -30ºC, extending to -40ºC in Paramos.
3. Built to endure wind pressures not exceeding 700Pa, equivalent to wind speeds of up to 34 m/s, ensuring stability in extreme weather.
4. Engineered to withstand earthquake intensities of up to 8 degrees, providing robust resilience.
5. Suitable for stable environments without frequent or violent vibrations, ensuring reliable operation.
6. The standard isolator must be installed in areas free from gas, smoke, chemical deposits, salt-spray fog, dust, or other explosive and corrosive elements that could impair insulation and conduction capabilities.
7. Pollution-proof isolators are tailored for heavily contaminated areas; however, they must be clear of explosive materials and fire hazards.
Scope
The Type IST off-load switches are expertly crafted for tropical zones, thriving in environments with maximum temperatures around 40 degrees Centigrade, and an average of 28 degrees Centigrade amid high humidity and substantial rainfall. These switches are ideally operational at altitudes up to 1800 meters above sea level, ensuring exceptional performance.
Electrical System
The Type IST off-load isolator switches are designed for continuous operation within a 3-phase, 3-wire system ranging from 11 to 36kV, across 50/60Hz distribution systems. With the star-point of the source-point transformer earthed via an Arc Suppression Coil or an Earthing Resistor, these switches guarantee reliable functionality.
Standards
The Type IST off-load isolator switches adhere to the stringent requirements of the following standards, inclusive of all current amendments, ensuring top-tier quality and safety;
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
