A trough type cable tray is a continuous rigid structure used to securely support insulated electrical cables and raceways. Unlike ladder-type trays, it features a solid or ventilated bottom that provides superior cable support and protection against dust. A cable tray (or simply a cable tray) is a rigid structural system that closely supports cables and consists of trough-, tray-, or stepped-type straight sections, elbows, tees, and crosses, as well as brackets (arm-type supports) and hangers. In environments where dust, moisture, oil mist, or mechanical impact are real risks, open cable tray systems often fall. Fluid Design The built-in radius of Cablofil Trough tray effectively eliminates any sharp angles and bends in the cable pathway that cause pinching and micro crack stresses in fiber optic cabling. Its one-piece design integrates the side rails and bottom for a cable pathway that eliminates cable. Cable tray structure (1) Cable tray is a general term for ladder-type, tray-type, and trough-type cable trays. (2) According to the structural form, it is.
