SITC of Lightning Arrester

Supply and installation by OEM or Authorized channel Partner of OEM, of external, wide area, early steamer emission OPR 30 type lightning arrester made of robust stainless steel & tested Standard stated in French Standard NF C17- 102, and IEC 62305-2. It is capable of polarizing the tip with a voltage of 600V to 10-20kV/m synchronized with an approaching lightning and triggering a powerful upward streamer with speed of 1m/µs into the air, with average time gain of 25 microseconds earlier than naturally formed streamers. Its upward streamers are strong enough to withstand applicable cyclonic wind speeds.The serial number displayed on the ESE lightning arrester shall be duly supported with the "certificate of country of origin" issued indicating the serial number of the product supplied. The ESE terminal must offer protection radius of 48 Mtrs. in Protection Level - I (high protection) and preferably to be mounted on the roof top of the building. ( Make: ABB)

Supply and installation by OEM or Authorized channel Partner of OEM of stainless steel support Mounting Mast 30 mm dia to hold early steamer emission OPR 30, of robust design with guy wire and base plate alongwith all accessories like clamps, shaddles, holding arrangements to fix mast to building structure at highest point such that the air terminal is 5 mtrs above the tallest structure Mounting Mast. (2 Mtrs. and 3 Mtrs. with Guy wire and Base Plate)

Supply and installation of lightning Stroke Counter by OEM or Authorized channel Partner of OEM working electro mechanically without any power supply.The recorder shall be of non-resettable type with the electro-mechanical display. No LCD screen is permittted as it may depend upon the battery life to energize the LCD. The lightning stroke recorder shall be duly tested & certified inline with the ESE lightning arrseter in an international labortaory for an impulse current (8/20 micro sec) and should count lightning strokes of 0.4 Ka to 150 Ka. ( Make ABB )
