Home / Expansion Joints and Compensators for Cable Trays
Among our most requested solutions are cable tray joints and expansion joints, which allow flexibility and compensate for thermal expansion, maintaining the alignment and mechanical strength of the system even under temperature variations. " In 1993 NEC Article 318 there are no requirements for the handling of the thermal contraction and expansion of cable tray. In this guide, the expansion gaps are explained to be calculated, as well as how to select materials such as aluminum or steel. As cables and trays expand or contract, they can cause stress on the structure, leading to potential damage or misalignment. Today's large scale infrastructure projects come with their own set of unique challenges.
