Model Number: SLZ1-#9158 Brand Name: Selong Key Specifications/Special Features: Ionization pre-discharge lightning rod based on traditionaldischarge theory, added promote ionization pre-dischargeperformanceAchieve earlier discharge than common lightning rods, meanwhileenlarge protection radius and increase protection performanceOperating theory: lightning discharge physical phenomena isover length gap dischargeA whole discharge process including: precursor, main bodydischarge and residual lightWhen analyze lightning discharge theory, to find instant oflightning discharge to grounding, local spaces electric filed whichnear to grounding to more than ten thousand V/m

Various top objects (various buildings, peaks and large trees)which among this electric field all will be induced and generatelarge electric charge (polarity is contrary to bottom of lightningcloud)

Because metal have nice conductibility, especially lightningrod tip will attach electric charge more easily from low to highelectric charge filed

If meet electrostatic induction, tip of lightning rod alwayswith attract large electric charge

Theory lightning rod usage feature:

• Lightning rod have two large potential various that bring fromatmospheric electric field
• Great deal of ionization upwards spread and emerge anticipationdischarge channel, when channel connect the lightning clouddownwards channel, lightning will be quick and safe connected togrounding
