Cable sag results from incorrect spacing of cable tray supports or from employing the incorrect tray type that is, light-duty perforated trays in high-load applications. Complicating the problem are overloaded trays and large unsupported spans. Consequences: Sagging causes tension at connection. Cable Tray Installation Spacing plays a huge role in the safety, efficiency, and reliability of electrical systems. In this guide, we'll explore why the spacing might be too wide, the problems it causes, and practical. Metal becomes bigger when hot and smaller when cold. 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 transposed to si osure, overheating or.
