Product Introduction:
YTC3991 Vacuum Degree TesterAccording to the JB8738—1998 standard "3.6—40.5KV AC High-Voltage Switchgear with Vacuum Arc Extinguishing Chambers" formulated by the "National High-Voltage Switchgear Standardization Technical Committee", the "internal gas pressure measurement and allowable storage period inspection" is a mandatory test item for units producing and using high-voltage switchgear vacuum arc extinguishing chambers, and the allowable storage period of the arc extinguishing chamber is specified as 20 years. The internal gas pressure of the vacuum arc extinguishing chamber should be lower than 6.6×10-2Pa.
YTC3991 Vacuum Degree Tester is a product improved by our company based on the feedback from field users on the previous generation. This vacuum degree tester features higher testing accuracy, better stability, and higher intelligence.
