Simple interlocking stripwound flexible metal conduits protected by galvanised steel braided sleeving. made from Sendzimir hot-dip galvanised profiled stainless steel helical strip (UNI EN 10346:2009) with simple or reinforced interlocking (ref. in table). The conduits are protected by galvanised steel braided sleeving. They provide excellent flexibility and good mechanical resistance together with good protection against electro-magnetic interference. They are used in industrial applications where a high level of thermal resistance is required. With TN connectors the system is without any plastic materials.
