Features:

Xizi Energy’s direct insertion SF6 gas pressure gauge is purpose-built for 12kV/24kV SF6 ring main units (RMUs) and gas-insulated switchgear. Featuring a long stainless steel insertion stem, it enables direct mounting into gas chambers for reliable, visual pressure monitoring.
Equipped with a color-coded dial (red for low pressure, green for normal), it provides instant on-site status checks. The mechanical design requires no power, ensuring stable performance in harsh environments (-30°C to +60°C) with high accuracy and IP65 protection. Compliant with IEC standards, it is ideal for utility grids, industrial substations, and data centers seeking early leak detection and safe grid operation.
