Triple-layer polymer smooth-walled pipe d. 90mm SN64 section 12m, halogen-free, color red 3908212SN64 DKC

DKS smooth heat-resistant polymer pipes with a triple-layer wall are designed for the mechanical protection of high-voltage cable lines up to 500 kV from mechanical impacts and aggressive environments under maximum transport loads. The inner layer is made of a blue non-flammable polymer composite (flame retardancy PV-0) and is resistant to short-circuit effects in the cable; the main layer is made of primary heat-resistant polymer for enhanced weldability; the outer marker layer is made of a light-stabilized red polymer composite with four identification stripes. Connection method: butt welding with a heated tool or using electrofusion couplings. Supplied in 12m sections. Outer diameter 90mm, Wall thickness 8.2mm.
