sf6 gas pipes for Transformers

Gas Monitor System: The insulating and interrupting capability of the SF6 gas depends on the density of the SF6 gas is at a minimum level established by design tests. The pressure of the SF6 gas varies with temperature, so a mechanical temperature-compensated pressure switch is used to monitor the equivalent of gas density.
