OEM Inflatable Duct Sealing Bags - Leading OEM & ODM Manufacturer for Fiber Optic and Textile Cable Applications | Wholesale Duct Sealing Solutions Provider

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.

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.                          

1) Simple and fast sealing

ITCS culvert sealing system is made to a sealed airbag with the flexible metal composite material, with good pressure resistance, resistance 

to corrosion and fire-retardant, good expansion filling effect. Both sides fitted with sealing tape, applying the movable inflation hose and 

automatic silicone valve. Products simply wrapped around the cable, into the pipeline. Then, connect the inflation tool and inflated, the joint

of pipe wall and cable is filled tightly by products inflated expansion. The entire installation process only needs to monitor the inflation 

pressure, one work can complete the installation within 2-3 minutes. Even in a crowded complex environment can be simple and quickly 

operated. There is no any mess mixing and filling process. The pipe sealing product of each specification may cover a wide range of cable 

and pipe diameters.

 2) Dismantlement with no damage

This pipe sealing systems are more likely to be removed from the pipe than other piping sealing systems. To ensure that pipes will not be 

damaged at the time of the cable's upgrade or replacement.

 3) Strong environmental adaptability

Products can adapt to a wide range of ambient temperature changes, at the state of -15 ºC -60 ºC the airbag and the sealing material is not

aging. Products can long withstand the acid and alkali corrosion in the groundwater, rain and salt fog.. Compared with other sealing methods 

which need the construction of dry pipe, ITCS pipe sealing system can be installed into the pipe where the water still flows, and can withstand

a large water pressure.

 4) Blank sealing and plural-culvert

According to different pipe diameters, ITCS pipe sealing system can seal the pipes with blank conduct and containing three or more cables. 

The waterproofing clip which can be inserted between cables is one of the technical methods.

The innovative technology of looping cable sealing is not only applicable to pipe sealing installation for new cable, but also applicable to

sealing upgrade or replacement for the existing culvert. The flexible sealing technology ensures that products can withstand cables' axial

tension and low-frequency vibration in a small range after installation. Form a buffer area between the pipe opening and cables, to avoid 

the cable shield wear which may appear movement between the cable tray. Arc-shaped surface formed by products' expansion has a 

certain flexibility, not susceptible to the chewing and wrecked by small animals.
