Steel support rail, torsionally rigid, made of galvanized, profiled steel sheet with a zinc coating, combined with polyester resin paint, ensures good corrosion protection. The universal support rail is suitable for light bands of all protection classes from IP20 to IP64. Flat ribbon cable is factory-installed and wired to a quick-mount connector. The maximum distance between the vertical suspensions is defined by the weight of the light band. For a free-hanging light band with 1500 units in electronic ballast version, the distance between vertical suspensions can be increased to a maximum of 3.5 m. For larger distances up to 4.5 m, there is the option to suspend using the SDT-AP suspension profile or via an M-suspension with a central hanger SDT-ZA. Note: The suspensions are designed only for horizontal arrangement of the light bands. For angled suspensions or other arrangements, please consult. Connection and mounting accessories, as well as rail end pieces and connectors, must be ordered separately. SDT 1500III 5x2.5mm2 vw RAL9016.
