LIGHTNING PROTECTION ELECTROSTATIC SYSTEM Kurn air terminal lightning conductor .No extra power required fi = 7 LY * Protection area until 150 meter (radius) Ae 160 Lf SS i ji Early streamer emission lightning conductor \ Non - radio active f / 1 year product warrantyLIGHTNING al Air Terminal Downconductor | Downconductor ——-| Downconductor Lightning Earth —— Lightning Farth Lightning Earth Lightning strike ocour of the change of electrical load (negative charges) from the cloud to the surface of the ground, chose the highest object that containing electrical load (positive charges ). We can see “Step leadrer” lightning strike, it is like a glowing lines on the sky. Effect from the lightning strike can causes very serious damages to building, occupants and electrical equipment. We need lightning conductor to protected. There is three lightning conductor type : 1. Conventional conductor 2, Radio active conductor 3. Electrostatic conductor KUR«iis the pioneer of lightning conductor electrostatic system from Indonesia, have a larger protection area, efficient an low maintenance (KURN use existing power from’ negative / positive charges of the grounding system). KURQ AIR TERMINAL 1. Head Copper As main conductor to capture the lightning and pass- ing charges via the cable ( downconductor ) to the grounding system 2. Disch Vertical Collecting negative charges from the air, with the disch horizontal produces free electrons to initiate an upward streamer Disch Horizontal This part has function as positive charges conductor from the electro generator unit to create corona effect (as Early Streamer Emission / ESE ) 4. Body Terminal There is an electronic part ( Electro Generator Unit / EGU ) in the body terminal. Processing positive charges from the grounding system and it does not require external power source 5. Connecting Sleeve Connecting body terminal and insulator for reducing risk of side flashing from the lightning strike energy to the mast »KURRUGHTNING CONDUCTOR KURN R - 150 KURN R - 85 Specification : Specification : Weight 22.7 kg Weight :24kg Diameter 3in Diameter :3in Lenght 255m Lenght :45.0m Rad. Protection : 150m Rad. Protection : 85m PROTECTION AREA Protection fread To calculated radius protection area of KURN lightning conductor use a formula : Rp = Radius protection ( in meter ), from the central point where KURN lightning conductor located h = Hight of the point of the lightning conductor above the surface to be protected (height of mast + lenght of air terminal ) h = Maximum height emission can be reach from the lightning conductor power to. generate a chrages ( depends on KURN lightning conductor type ) Type KURN R - 150 h’ = 75 mand KUAN R- 85h’ = 40m at = Angle of cone above protection area is 60 degreesKU Ry LIGHTNING CONDUCTOR Each type of KURN lightning conductor PT have different range radius protection area and power fo generate corona effect oa RUB) ee Slee KURN R-85: protection area max 85 m KURN R-150 : protection area max 150 m Use the table for effective application Ey plan and chose the right type of KURN lightning conductor will installed ( see the CERTIFICATE AND PRODUCT TEST table at right ) = = KURN product test at Lik - PLN AURK Lightning protection passed test at LMK PLN and registered at desi iis ‘ey oflaw and human igh wih PATENT No 438333, + yeas product waranty to give you produc satis an wa raver spt rasearh and ‘evalop the product 2s our commitmen become he best gtning conductor made in do- ris ra LARA OLMKS Manual Insist
