TE Connectivity 828695-000 Sealing strip 1 pc(s)

Cable protection tube sealing for pipe inner diameter 75-120 mm. System with sealing sleeve and sealing star. Flexible plastic laminate bag, which is coated on both sides with sealing strips Watertight sealing of energy cables in plastic pipes, metal pipes and cement pipes as well as in core drilling. Patented gel valve prevents pressure loss and ensures long-term system leakage. Easy to dismantle. A round, smooth-walled inner surface is necessary. When used in installation pipes, a pressure rating of at least 3 bar must be ensured. The watertightness was carried out under a present pressure of 0.3 bar under stress of the cables with vibration, bending, torsion, train and thrust. Furthermore, the chemical and bacterial resistance was tested. Following VDE 0278 part 1, load-change tests were carried out with conductor temperatures of up to 90 °C. By measuring and calculating the diffusion rate, an average lifespan of 30 years was determined. The sealing behavior after 30 years was simulated and confirmed by leak tests with reduced internal pressure.
