DWC HDPE Electrical Duct/Pipe The DWC Duct/Pipes is designed as a technically superior and cost- effective solution for replacement of GI, RCC and PVC pipes in fiber 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 Duct/Pipes. The DWC Duct/Pipe 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. Berlia Dwc Pipe Ducts
