High Voltage Switchgear
01
HXGN-40.5 Gas-insulated Switchgear (GIS)
Features
● Safety & Reliability
The high-voltage components of this switchgear use low-pressure SF6 gas as the insulating medium, sealed in a stainless steel housing to isolate from the external environment. This effectively prevents contamination, moisture, foreign substances, and other harmful impacts, enhancing insulation reliability while offering excellent anti-aging and anti-corrosion properties.
● Compact Structure
Adopting mature vacuum switch technology with stable breaking performance and long service life, the arc extinguish chamber is horizontally arranged in the gas-filled housing. This fully leverages the excellent breaking capability of the vacuum interrupter, ensuring a compact structure, superior performance, and high reliability.
● Maintenance-Free
Using inner cone cable plug-in technology, cables, arresters, and PT can be connected via plug-in for stronger insulation. The gas box features a dual-chamber design: one chamber for the three-position switch and main busbar, and another for the circuit breaker unit, supporting one-key sequential control.
● Easy Installation
With solid insulated busbars, this gas-insulated switchgear eliminates on-site SF6 gas handling issues (e.g., vacuum pumping, gas filling, moisture treatment) during installation and operation expansion, enabling convenient field installation.
● Intelligent Configuration
Equipped with intelligent control and protection units, it monitors the operating status of circuit breakers, three-position disconnectors, energy-storage springs, and gas pressure in the gas-filled housing. It controls the opening/closing of circuit breakers and operation of three-position disconnectors, achieving relay protection automation.
