7 Ways 12/10 mm DB HDPE Tube
7 WAYS
A bundle of micro- or mini-tubes (regular wall size) is surrounded by dual HDPE sheath. The design makes the duct assemblies suitable for outdoor direct bury application. The inner micro ducts are optimized for best cable blowing performance.
Raw materials
HDPE of a high-molecular type with the following parameters is used for production of the Tube Bundle: - Melt flow index: 0.1 ～ 0.4 g/10 minutes EN ISO 1133 - Density: Min. 0.940 g/cm3 ISO 1183 - Tensile strength at yield: Min. 20MPa ISO 527 - Elongation at the break: Min 350% ISO 527 - Environmental stress crack resist (F50) Min. 96 hours ISO 4599
