HVGC Series – High Voltage Gas-Insulated Switchgear Components
The HVGC series represents a comprehensive range of high-voltage gas-insulated switchgear (GIS) components designed for medium to high voltage distribution networks. These products typically include circuit breakers, disconnectors, earthing switches, and busbar systems rated for voltages from 72.5 kV up to 550 kV, with rated currents ranging from 1250 A to 4000 A. The gas-insulated design uses SF6 or alternative eco-friendly gases to achieve compact dimensions, high reliability, and minimal maintenance. Key technical parameters include short-circuit breaking capacity up to 63 kA, rated frequency of 50/60 Hz, and insulation levels compliant with IEC 62271 standards. The modular construction allows for flexible configurations in substations, with integrated monitoring systems for partial discharge and gas density.
HVGC components are primarily deployed in high-voltage substations for power transmission and distribution, industrial plants with heavy electrical loads, renewable energy farms (solar, wind), and large-scale infrastructure projects like railways and data centers. They are essential for switchyards, GIS substations, and ring main units where space is constrained and reliability is critical. The gas-insulated technology ensures operation in harsh environments, including coastal areas, deserts, and high-altitude installations, with IP65 protection ratings for outdoor enclosures.
Key subcategories within the HVGC series include HVGC-CB (circuit breakers), HVGC-DS (disconnectors), HVGC-ES (earthing switches), and HVGC-BB (busbar systems). Article codes typically follow the pattern HVGC-XXXX-YY, where XXXX denotes the voltage class (e.g., 145 for 145 kV) and YY indicates the rated current in kA (e.g., 25 for 2500 A). For example, HVGC-145-25 refers to a 145 kV, 2500 A circuit breaker. Other common codes include HVGC-245-40 for 245 kV, 4000 A disconnectors and HVGC-72-12 for 72.5 kV, 1250 A earthing switches. These components are available with various actuator types (spring, hydraulic, or motor-operated) and control voltages (110 VDC, 220 VAC).
