high voltage Pressure gauge Development trend
Absolute pressure: it is measured with relation to perfect vacuum, namely, the pressure difference at a given measurement point by the vacuum pressure (absolute zero). Normally the ABS notation is used when this greatness is indicated. Example: The absolute pressure applied by the atmosphere at sea level is 760mmHg.

110kV CIRCUIT BREAKER gas Rules Dangerous
2013/3/20An SF6 circuit breaker is a type of circuit breaker in which sulphur hexafluoride gas or SF 6 gas is used as the arc quinching medium, known as an SF6 circuit breaker. SF 6 gas has excellent insulating property and it has a high electronegativity. Due to high electronegativity, it has a high affinity for absorbing free electrons.
