Completed packages of the HDPE Tube Bundle on drums can be stored outdoor max. 6 months upon the date of production. Storage temperature: -40°C ～ +70°C Installation temperature: -30°C ～ +50°C Operating temperature: -40°C ～ +70°C
Design
- A bundle of micro- or mini-tubes (strengthened wall size) is surrounded by single thin HDPE sheath. The design makes the duct assemblies suitable for installation in other existing ducts or underground direct bury. The micro ducts are optimized for best cable blowing performance. - The inner micro duct has suitable low friction characteristics on the inside surface. The micro duct has colors according to figures 1.
