Ceramic gas discharge tube of the sealed package, in the spark gap filling in the appropriate gas medium (argon or NaiQi), match with highly active electronic launch materials and discharge ignites institutions, is a special kind of metal ceramic structure of the gas discharge device.
In normal circumstances, discharge tube for its unique high impedance quartile (1000 M Ω) and low capacitance (or 2 pF) characteristics, as protection components access lines when the normal work of the line to almost nothing disadvantageous effects, and when the transient overvoltage into harmful, discharge tube was first breakdown discharge. The impedance fell rapidly, almost a short circuit state. Will the current through the wire and the relief is harmful to the earth, at the same time, the voltage limit in discharge tube's arc (about 20 V), eliminated harmful instantaneous overvoltage and over current, from
