Helium leak detection                                                                                                                                       ≤1.0x10-8pa·m³/S

Insulation resistance of positive and negative poles and cover sheets at 500V                                                       ＞200Mohm 

Surface resistance from the upper surface of the positive and negative poles to the bottom of the poles            ≤0.05Mohm

Positive and negative pole torque                                           >8N.m 

The explosion-proof valve is 0.15MPa from the inside to the outside, and the air pressure is 0.15MPa from the outside to the inside. Each state lasts for 30S. After 10 cycles of the breath test, there is no air leakage, and the blasting pressure is not lower than 0.4MPa
