[0002] As a common support and protection device for cable laying in the power supply system of electrical equipment, the cable tray plays a role in protecting the cables laid in the cable tray and guiding the wiring. Traditional cable trays are mainly divided into structures such as trough type, ladder type, tray type, and grid type.

[0003] The internal fixing structure of the existing cable tray is relatively single, and the stability performance is poor. Moreover, generally multiple cable lines are placed inside it, and the cable lines are rather messy and will contact and wind together, affecting heat dissipation and reducing the use effect of the cable tray. For this reason, we propose a molded built-in steel skeleton cable tray to solve the above problems. Content of the Utility Model
