Lightning protection system

Lightning protection system 1. ERICO type 2. Stainless steel material

 Lightning protection system

BLJ-I principle of workWhen the thunder and lightning during the formation of clouds, between cloud and ground to produce a field, this field strength can reach 10KV / m or even higher. So that raised some or metal parts on the ground began to appear on the corona discharge. When the thunder and lightning inside the clouds, forming a downlink pilot, the lightning electric shocks began. Charge in the form of the pilot ladder down to the ground move. Close to the ground the moment when the pilot line will be from the ground to issue a more prominent part of the title of head-up guide. When the head-down pilot and the pilot met, it creates a strong "and in" process, there may be great current (tens to several Mochi security), which is the main lightning discharge stage, accompanied by a massive thunder and flash . Other buildings on the ground may be generated in several head-on leader. Downlink pilot with the first one to join the pilot decided to face the location of the lightning strike. LTDT-I early discharge lightning rod works is to create a head faster than ordinary lightning rod leader. In the face of nature before the formation of the pilot, LTDT-I will be the first to produce a pilot and quickly spread to the direction of up to capture lightning thunder and lightning, and its import earth. Laboratory confirmed: produced earlier than the regular pin head-start pre-empt the time of this pilot is called ΔT, given BLJ-I more effective lightning protection. Note: This description is only described in negative downward lightning lightning, which is electric - the only geometric model of an application example. So far, this lightning lightning is the most frequently occur.
