air inflatable seals are used to seal cable running in ducts against water and gases. They feature full re usability, sealing of multiple cables without separation clips and durable sealing behaviour (>20 years), reducing total cost of ownership with regards to alternative sealing solutions. Furthermore, they use no CO2 as inflating agent, then protecting our environment.
Reasons for using sealing technology for feedthroughs to protect against water entry or gas diffusion e.g. carbon monoxide
ï?·Prevention of personal injury caused by gas diffusion
ï?·Prevention of damage to property in buildings and technical rooms
ï?·Prevention of short-circuits caused by water entry
ï?·Prevention of network failure caused by optical fibre breakage
(optical fibres are particularly sensitive to water entry or immersion in water)
Cable manhole facilities do not have to be pumped out
Prevention of costly repair and renovation measures
Inflatable Cable pipeline Seals systems
The culvert without the application of sealing construction will bring the humidity and stagnant water to substation basement, culvert and manual well. In such environment, the corrosions and damages to culvert tray and electrical equipment are unavoidable. The common method is the use of inflatable type culvert sealing product, to stop the water into underground culverts nearby these facilities in a simple and effective way.
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
Application
1.For power cables.
2.For two or more cables,sealing clips are required.
3.Inflation tool is available to provide.
4.Casters of compressed air or CO2 are COMPATIBLE, or water.
5.Each seal covers a large range of cable and duct diameters.
6.IDSS seals can be installed when water is still flowing out of the duct_saving valuable installation time.
7.Use not only for new cable installations but also for existing applications.
8.IDSS seals can be quickly and easily removed from a duct or pipe by deflation.
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.

Fabric Innerduct Features
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, such as A, 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.
Application
Our fabric innerduct has been successfully installed in a variety of applications including:Broadband, Telecommute, Military, Data Centers, Wireless back-haul, Power/Utilities, Municipalities, Government, University, Healthcare, Airport and� Corporate Campuses.
Fabric Innerduct maximizes the pipeline's network infrastructure while addressing conduit cabling issues, allowing for a variety of cable sizes, reducing or eliminating the number of conduits required in new structures, when overwriting existing cables or traditional internal piping Easily create paths while reducing material and labor costs and increasing installation speed.
