PREVECTRON® 2 - E. S. E. Lightning Conductors
	AVKO JSC offers lighting-protectors PREVECTRON® 2, produced by INDELEC® - France and we are the one and only representative for Bulgaria of this product.
			Key benefits The skills of INDELEC’s engineers, the variety of tests carried out in both high-voltage laboratories and real-life lightning conditions, and the experience gained from the thousands of PREVECTRON®2 installations around the world, have allowed us to develop a complete range of lightning conductors offering a host of key benefits:
			6-model range offering customized solutions for each project (easthetic constraints, required protection area, etc.) fully autonomous operation total reliability, even in extreme climatic conditions proven, robust design able to withstand multiple lightning strikes lightning conductor only becomes active when electrical field intensity rises (lightning discharge likely), the PREVECTRON®2 presents no danger to the site straightforward installation & maintenance using tools specially developed by INDELEC, including protection calculation software, strike counter and PREVECTRON® tester high-voltage laboratory test results available on request real-life test results & scientific reports available on request ultra-safe capture tip thanks to full electrical continuity between the tip and the earth point ISO 9001-2000 manufacturing process (certificate No.116884)
			Protection area The protection area Rp of a PREVECTRON®2 lightning conductor is calculated according to French Standard NF C 17-102, thus The protection area depends on a number of factors:
			Gain in triggering time T(µs) of the chosen PREVECTRON®2 L(m) = V(m/µs); V* = 1 m/µs T* S 6.60 S 4.50 S 3.40 TS 3.40 TS 2.25 60 50 40 40 25 * values obtained through tests conducted in high voltage laboratories. D(m) = 20, 45, or 60, depending on the protection level required (I, II, or III) on a given site, according to the lightning risk assessment guide. the actual height of the lightning air terminal above the surface to be protected: h (where h < 5 m, for Rp see table below).
