Double walled corrugated (dwc) ductThe Dwc duct is designed as a technically superior and cost-effective solution for replacement of GI, RCC and PVC pipes in fibre optic and electric cable networks. Manufactured from rugged and virgin High Density Polyethylene (HDPE), this duct has a double-walled construction. This unique construction, while making it light-weight, gives excellent mechanical properties like high ring stiffness, better impact strength and superior crush resistance. The smooth inner wall facilitates easy insertion of ducts and cables in Dwc The Dwc duct has the ability to withstand heavy external loads when properly buried and back filled. Hence, it is ideally suited for usage as Jacket/Casing duct in those environments where direct placement of ducts and cables is not safe and easy.Dwc Advantage Much longer life as compared to GI, RCC and PVC pipes Light weight and therefore easy to transport, handle and install Ability to take heavy loads due to good mechanical properties Chemically inert and therefore suitable for use in saline/coastal areas No sharp edges and therefore safe for duct/cable installation Flexible to take bends and curves around obstacles Dwc Applications Telecom Applications Used as the main duct in main-duct/sub-duct network design Protection of ducts across rivers, culverts and disused canals (nallahas) Protection of ducts in rail/road crossings Protection of ducts and optic fibre cables in city networks Casing of copper cables Used as a casing duct for simultaneous placement of quad cables and optic fibre cables along railway tracksDwc Technical Details Compression Test IS 14930 (Part 2) 450 N at 5% deflection at -5o C for 2 hrs Impact Test IS 14930 (Part 2) No crack or split when 5 kg load is dropped from,
