  • Electrical busbar trunking integrated with cable tray

    Electrical busbar trunking integrated with cable tray

    Track Busway ROWs with integrated cable tray combine overhead power distribution and structured cable management in a single suspended system. This layout supports plug-in power drops while providing a dedicated pathway for data, control, or low-voltage cabling. EAE cable trays are produced on automatic production lines through the 'ROLL FORMING' method. The standard tray length is 3m. E-Line TB and E-Line URC. Busbar systems are often preferred over cables because they save space, install faster, offer greater flexibility for changes, and provide enhanced reliability, frequently leading to a lower total cost of ownership. The SIVACON 8PS BD2 system is the universal busbar for high performance within a small space—an innovative, flexible alternative. 1. Trough cable Tray adopts closed design, which can effectively prevent the cable from being damaged by external factors and ensure the service life of the cable.
