Sound-absorbing spiral duct consisting of perforated inner tube wrapped with glass fleece protection over mineral wool, non-flammable according to DIN 4102, fire behavior A1, bio-soluble in accordance with TRGS 905 and EU Directive 97/69/EG, the insulating materials are. The spiraling technique consists in coupling a series of adhesive-coated strips, winding them around a mandrel, obtaining a tubular whose electrical, thermal, impregnation and mechanical characteristics are the sum of the ones of each layer. Politubes uses only the best high quality insulating. Camozzi offers a range of tubes and spirals with specific features which are suitable for several technical requirements. They also show high resistance against stress and flexural. Spiral winding tubes in electronics are used for electrical insulation, mechanical protection and bundling of cables, wires and connections. Different wall thicknesses could be produced according to your demands. The standard length is up to 6 000 mm. materials: PE-HD, PE-80, PE-100, PE natural, PE-EL, PE coloured PP-H. Cable containing up to 6 optical fibers in spiral stainless steel tube, optical fibers reinforced with water blocking aramid yarns and sheathed in a flame retardant Low Smoke Zero Halogen compound. Indoor/Outdoor cable is designed for internal or outdoor use primarily in structured wiring systems.
