Selection Of Cable Tray Structural Types

In engineering design documents, cable trays are often referred to simply as "trays" without specifying their structural characteristics. However, prices vary significantly depending on the type and material of the cable tray, and ambiguity regarding the structural type can lead to issues with heat dissipation and mechanical protection at the installation site. Therefore, during the design phase, designers should be required to select appropriate structural characteristics based on the project environment and technical requirements, and to clearly indicate these details in the model designations on layout drawings and in the materials schedule.
