Parallel diameter changer for cable trays
A parallel diameter changer for cable trays is typically implemented using reduction fittings or adjustable-width components that allow the tray width to change while keeping cables aligned in parallel.Function and PurposeA parallel diameter changer is used when the width of a cable tray needs to be increased or decreased to accommodate different cable volumes or sizes without disrupting the parallel routing of cables. This ensures that cables remain organized, supported, and compliant with electrical installation standards, while preventing overcrowding or mechanical stress on the cables .Implementation in Cable Tray SystemsReduction Fittings: These are specialized fittings that connect two cable trays of different widths. They maintain the alignment of cables and allow a smooth transition from a wider to a narrower tray or vice versa .Adjustable or Modular Trays: Some cable tray systems offer modular components that can be adjusted in width, effectively serving as a parallel diameter changer. These are particularly useful in industrial environments where cable volumes may vary over time .Installation Considerations: The fitting should be supported by appropriate support elements such as wall brackets, suspended supports, or center suspensions to handle the mechanical load of the cables and the tray itself . Proper mounting ensures safety and compliance with standards like DIN EN 61537 or BS EN 61537 .Practical TipsEnsure the material and corrosion protection of the fitting matches the rest of the cable tray system (e.g., galvanized steel or stainless steel) to maintain durability .Verify that the load rating of the reduction fitting or adjustable tray section can support the total weight of the cables, including any dynamic forces such as vibration or short-circuit events .Use accessories like barrier strips or covers if needed to protect cables during the transition between different tray widths .SummaryA parallel diameter changer is essentially a reduction or adjustable-width fitting that allows cable trays to change size while keeping cables aligned in parallel. Proper selection, installation, and support are critical to ensure mechanical stability, safety, and compliance with electrical standards .
