First, use  
YL Series Gas Filled Standard Capacitor-- mainly as resistance to a high standard bridge arm for the precise measurement of high voltage electrical equipment and insulation material value of the capacitance and loss tangent; Capacitive voltage divider can also be used as a high capacitance, and PD measurement circuit of coupling capacitance.  
Second, the use of the environment  
Indoors.   Installation and operation of environmental air temperature range (indoor) : -5~40 ¡æ   Relative humidity less than 75%.   Installation and operation of not more than 1000m above sea level.   Installation sites should not damage the surface of the capacitor insulation of chemical gas, dust and high temperature heat conductivity.

Third, the structure brief  
From the electrode capacitors, and other components, shell, the internal fully compressed SF6.   Electrode pressure from the electrodes, shielding measuring electrode and electrode composition, electrode systems for both shielding structure.   Rated capacity 100pF capacitor casing of the standard insulation cones for the cylindrical electrodes.   500~1000pF rated capacity of standard high-strength aluminum alloy cylinder shell capacitor electrode to the plate.
