| 1 | 1 | Supply of ESE Air Terminal ESE -60. Early streamer Emission type Air Terminal should offer Radius of protection 79Mtrs in level I. Air Terminal comprised of separate electrically isolated dual panels surrounding an Earthed central finial should be coated with chrome for environmental protection. The upper section of the central finial shall be rated to withstand 40KA impulse current and it should be made up of solid brass rod and its length should be more than 85mm above the surrounding panels. The insulation material used to electrically isolate the panel shall be comprised of base polymer which provides high UV resistance with die electric strength of 24-38KV/MM & ESE terminal shall withstand a minimum switching impulse voltage of 500KV. Its adapter should be made up of non conductive material DELRIN, which should provide good abrasion resistance, Good mechanical strength, pretty good heat resistance, good electric &dielectric properties & Low water absorption. Terminal performance should be tested as per NFC 17-102:2011. Performance should be tested in European Accredited lab after 2011 also its impulse current withstand test should be carried out in CPRI for 40KA 5+ve & 5-ve test. Terminal should be non electronic& does not require any battery backup or power supply for operation because of battery life & sustainability. Supplier should show on site testing of Continuity of Air Terminal Tip to Adapter. Protection Radius : 79Mtr Level I @ 5mtr Height | BI01010001010000000000000515BI0100001113 | 3 | Nos |
| 2 | 2 | Supporting Mast: The mounting pole used to support the lightning air terminal shall either be a supporting mast or Free standing mast at a ideal height of 05 metres above to be area protected or as per required level of protection. If any height restrictions are there then min height should be 2mtr but radius of protection will change according to height. The mounting pole and supports shall be securely fixed with brackets and guy wires where required to withstand maximum locally recorded wind velocity. Mounting Pole shall be non corrosive and made up of medium class GI pipe of 2\" dia having base plate at bottom for securely fixing mast on rooftop. Also PVC insulated metallic wire rope should be used for guying purpose. The down conductor shall pass through the centre of the pole for the entire length of the pole and it will be out at bottom of the pole. All the mounting accessories should be non corrosive and made up of SS. Supporting Guyed Mast : 05Mtr x 2\" dia with base plate, guying kit and mounting accessories. | BI01010001010000000000000515BI0100001114 | 3 | Nos |
