Microduct HDPE Tube Bundle Direct Bury

Microduct HDPE Tube Bundle Direct Bury​

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.

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 (190 °C, 2.16 KG)
• Density: Min. 0.940 g/cm3 ISO 1183
• Tensile strength at yield: Min. 20MPa
• Elongation at the break: Min 350%
• Environmental stress crack resist (F50) Min. 96 hours

Construction:
-PE sheath: The outer sheath is manufactured from colored HDPE, halogen free.
-Micro duct: The micro duct is manufactured from HDPE, extruded from 100% virgin material.

Features
-Robust, highly resistant to crushing and external impact
-Suitable for all environments
-Long life time, over 30 years
-Temperature resistance in extreme environment
