The International Electrotechnical Commission (IEC) provides detailed guidelines for cable tray systems under IEC 61537. This standard outlines the construction requirements, testing methods, and performance parameters for cable trays and related support systems. For almost 100 years, OBO has been devel-oping and producing standard-compliant lightning pro-tection components. The IEC technical committee is comprised of representatives from. The Lightning Protection Institute is a nationwide not-for-profit organization founded in 1955 to promote lightning protection education, awareness, and safety. The mechanical and electrical characteristics, tests, certifications, overall quality management, recommendations mentioned in this technical guide only apply to our own cable management ranges and cannot under any circumstances be transpos regulations which. At its core, lightning is a massive electrical spark between either the cloud and ground, ground and cloud, cloud and cloud, or cloud and upper atmosphere. The Cable Tray ng standards, performance standards, test standards and application in this document have been tested extens ompetent professional en completely installed, without damage either to conductors or.
