8. Main technical indexes
a. Seal performance : the pressure in the closure is 100Kpa,put the closure into the water for 15minutes,there is no air bubble ,and observed it for 24 hours ,there is no change of air pressure
b. Re-entry performance:after 3 times of normal operations ,it can still be up to the seal performance standard
c. Insulation resisitance: ≥2x104MΩ
d. Withstand voltage strength :there is no puncture and no arc-cover after the function of 15KVDC/1min.
