Fabric Innerduct Benefits

easyOSP Fabric Innerduct maximizes your conduit and network

Protection of Cable and External Pipe

Tensile strength of braided sub-pipe is more than 1 ,000 kg

Convenient construction of Braided Subpipe

Braided sub-pipe has no bending memory and doesn' t curl like PE sub-pipe;

Long Service Life

The textile sub-pipe has high chemical inertness and could be exposed to the severe underground environment for a long time with design life of 50 years.

Bent Freely in Connection point

Braided sub-pipe is not twisted during the laying and could be bent freely

Suitable to Long Distance Laying

The friction coefficient of braided sub-pipe is low and prevents the friction between cables

Newly added laying in Special Environment

Low requirement on construction site, especially in downtown area;

FAQs on Fabric Innerduct

Here below are some common questions on Fabric Innerduct, if you still have questions, Please feel free to contact us via [email protected]

Fabric Innerduct definition

An innerduct for segregating cables in a conduit is provided wherein the innerduct is constructed from one or more strip-shaped lengths of a woven textile fabric and configured to provide multiple longitudinal compartments for the cables, and the textile fabric has a warp of monofilament yarn ends and a filling of a combination of monofilament and multifilament yarn picks, with the multifilament yarn picks being multiple-inserted yarns.

Fabric Innerduct is the only flexible fabric innerduct system designed specifically for the network construction industry. The unique fabric construction greatly reducing the wasted space associated with rigid innerduct.

Inflatable type culvert sealing system, which have been widely used in the design of underground culvert constructions in the industries of electric system, telecommunications, port, urban construction, rail transportation and so on. Provide a clean and dry operating environment to cables and other electrical equipment after installation, improve the degree of protection, and reduce the works of cleaning up sludge and stagnant water in the manual well before the maintenance works.

Fabric Innerduct Specification

Fabric Innerduct specification

1.Light construction

The textile sub-tube has no bending memory; it does not curl like a PE sub-tube;

The textile sub-tube will not be kinked during laying and can be bent freely during laying;

The textile sub-tube is preset with high-strength draw tape in each hole, and the laying of the cable does not need to be through-hole, and the laying is more convenient and quick;

The construction site requirements are very small, especially suitable for busy districts.

2.Protection cable and outer tube

The breaking strength is above 1000 kg;

Textile tube melting point = 215。C, while HDPE sub-tube = 110。C;

The thermal expansion and contraction rate of the textile tube is 1/7 of that of the HDPE sub-tube;Prevents wear between cables.

3.long lasting

The textile sub-tube has high chemical inertness and can be exposed to a harsh underground environment for a long time. The design life is 30-50 years, and the life of the PE sub-tube is only 15 years.

4.Resolution recognition design

Two holes in the textile sub-tube product family, three holes will be preset with different colors of the draw tape for the differentiation during construction;

The textile sub-tube will print the meter mark when it leaves the factory to prevent unnecessary waste during construction;

When the textile sub-tube is delivered from the factory, it will be labeled according to the customer's needs, suchasA, B, C A1, A2, A3, etc., used to distinguish the multiple textile sub-tubes in the pipeline, to facilitate the maintenance of the line.

5.Environmentally friendly design concept

The textile sub-tube can reach 30-50 years underground. Ordinary HDPE sub-tubes will form slag due to aging in the ground for a long time, and become a blockage in the pipeline. The textile sub-tube solves this problem from the design concept and has high environmental protection for the pipeline.
