S/R to buildings such as Provision of lightening arrester system at Boys Hostel No.1 of Parala Maharaja Engineering College at Berhampur (Sitalapalli)

Supply, Installation, Testing and Commissioning of Lightning Protection System based on Standard Inrenational Trade Classification (SITC) of High Pulse Voltage OPR-60/ESE-60 Proactive Early Streamer Emission (ESE) Lightning Protection System with radius of 79 meters in Level-1. The lighting air terminal configured as a spheroid which is comprised of separated electrically isolated 4 pannels (stainless steel) sorrunding an earthed central final with The Air termination shall be of the type that response dynamically to the appearance of a lightning conductor should deliver a unique gain time in efficiency anticipating the natural formation of an upward leader that propagates rapidly to capture the lightning stroke and conduct it towards the ground. The insulation material used to electrically isolated the panels (stainless steel) is comprised of a base polymer which provides high Ozone & UV resistance with a di-electric strength of 24-38 KV/mm. The ESE terminal is tested & certified as per NFC 17-102 standard with the "Switching Impulse Voltage" of -700 KV and "Direct Voltage" of -70 KV. The early streamer emission terminal is tested & certified by CPRI (Central Power Research Institute), Govt of India for the Impulse current of 45 KA (8/20 micro sec) with 5 positive & 5 negative impulse. The ESE terminal is tested and certified by any international laboratory as per IEC 60-1:1989 for an impulse current (8/20 micro sec) of more than 160 KA. The serial number displayed on the ESE lightning arrester is duly supported with the "certificate of country of origin" issued and duly sealed by the respective country(Exported) . Make-ABB/SIEMENS/STORMKING-2CT8899800R7100 Test Report with Authorized Sign.
