Load-bearing standards for trapezoidal cable trays

Home / Load-bearing standards for trapezoidal cable trays

IEC 61537 is the international standard developed by the International Electrotechnical Commission (IEC). This standard outlines the construction requirements, testing methods, and performance parameters for cable trays and related support systems. The mechanical and electrical characteristics, tests, certifications, overall quality management, recommendations mentioned. maintain spacing or to keep cables in place when the tray is ect the minimum bend ra-dius for cables as they exit the bottom of the cable tray. When developing our cable support OBO can offer reliable solutions for systems, three attributes are at the routing and fastening cables securely core of what we do: efficiency, resil- for each of these installation challeng-ience and safety.
