HDPE 14/10mm Direct Buried 7 Way Microduct with Factory Price
Microduct assemblies are available for several installation environments such as direct buried installation, into existing pipes or for indoor installation.
Microducts are characterised by heavy wall microducts and a relatively thin outer sheath. The thickness of each inner tube allows
individual tubes to be used direct bury solution.
The microducts themselves are rugged enough to protect the fiber cables inside. Micro ducts are made of HDPE and have a low
friction inner surface for best blowing performance.

Advantages:
1). Adopt multi-machine co-extrusion, the silicon core layer is synchronously embedded in the pipe. It will be permanent lubricated and not be stripped forever
2). The friction coefficient of the inner wall is very small. Optical cable (electric cable) can be repeatedly extracted and tension in the pipe.
3). Waterproof, damp-proof, can avoid the damage by rodent animals.
4). Aging-resistant, anti corrosion of chemicals, long service with 50 years
5). Good weather resistant ability, and its suitable temperature from -40°C to 100°C.
6). Convenient in construction, save time and the project cost
Applications:
1. Developed to be the best solution of direct burial modular-tubes family, featuring a non-metallic construction.
2. 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 buried. The microducts are optimized for best cable blowing performance Storage
Completed packages of the HDPE tube bundle on drums can be stored outdoor max. 6 months upon the date of production.
Storage temperature -40℃ ~ +70℃
Installation temperature -20℃ ~ +50℃
Operating temperature -40℃ ~ +70℃
