SF6 ring network cabinet air pressure gauge is an important protection and control element in the power system, suitable for measuring the gas pressure monitoring in electrical equipment such as high voltage, medium voltage SF6 load switches and voltage cabinets in the transmission and transformer network system where SF6 gas is the insulating medium. And suitable for outdoor harsh external conditions
Applications
Sealed, pressurized enclosures for high-voltage switchgear, high-power transformers and other equipment
For switchgear, high-power transformers and submerged power and telecom cables
For cables filled with gas (e.g. SF6 gas)
Features
The housing is made of high quality stainless steel, never rusting, beautiful atmosphere
The density value displayed on the dial panel (corresponding pressure value at 20°C) and the green and red color indicated on the dial are different working areas, which are not affected by the ambient temperature
Temperature-sensitive components are made of imported materials, high precision, stable and reliable performance
Safe to use, easy to maintain, more flexible installation methods
With a variety of interface connection, can be used with various types of self-sealing valves, suitable for a variety of SF6 equipment at home and abroad
