Silicon Core Duct:1.Use in protcting optical cable or telecom cable.
2.Most advanced cable jecket material.
3.Low price.
Silicon Core Duct:
To catch up with the development of world telecom industry, our company researched and develop this product by our abundant technical strength and rich production experience through two years hard work. Its main characteristics are:
1. Adopt the mode of multi-machine co-extrusion, silicon core layer is synchronizely embedded in the pipe. It will be 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 tensioned in the pipe. Trough using cable blowing machine, one time blowing length can be 1000 to 2000 meter under normal conditions.
3. Good tightness, waterproof, damp-proof, can avoid the damage by rodent animals.
4. With great ring stiffness and toughness. In construction, its bending radius should not be less than 10 times of the external diameter of the pipe.
5. Aging-resistant, anticorrosion of chemicals. With long service life, and will not deteriorate within 50 years in the earth.
6. Good weather resistant ability, and its suitable temperature scope is from -40 to 100.
7. Convenient in construction. This will save time and the project cost is only 30% of the PVC pipe.
Good quality HDPE Duct.
Introduction to the product:
HDPE (high-density polyethylene) silicone duct for communication is a newly developed composite conduit with solid
silica gel lubricant in its internal wall. It is short for silicone duct. Its made by three plastic extruders. Its major raw material
is high-density polyethylene. Sandwich layer is solid silica gel lubricant of low friction coefficient. Owing to the special
extrusion molding technology, the internal wall of the duct becomes extremely smooth.
Product properties:
The internal wall of the duct is so smooth that cable blowing technology can be selected for optical cable and cable laying, which makes the construction simple, quick and economic. Moisture resistance, corrosion resistance and long service life.
Good insulating performance and long service life (underground duct can be used for 50 years), durable, easy for maintenance, ensure of a safe operation of the line.The duct can be coiled with not much joints, easy for installation, and duct length can be as long as 3000m.High pressure resistance, system enlarging, maintenance is very convenient and cost is low.
Application scope
Applies to the piping system of outside communication cable and optical cable, or construction for public information network, public transmission system, cable television network and freeway communication.

Technical standard:
Color: Black is the base color, color code on the surface of the duct is distinguished by brown, grey, orange, blue, red, purple, green and yellow. Product supplying is based on requirements.
Appearance: The color and luster is even and unanimous, internal and external wall are smooth without obvious foreign matters and defects, no air bubble, no crack. Internal wall of the silicone duct is closely fused, no split. Both edges are smooth and vertical to th axis. Inside silica gel layer is even distributed. Coil packing is used.
