Cable entry system HSI150/HSI90

Water- and Gas-Tight Installation for Maximum Security

House entries can break vapor and moisture barriers, posing a risk. Hauff-Technik’s cable entry system provides builders and property owners with a secure solution, ensuring full protection from gas and moisture infiltration for both the entry and individual utility lines.

The system uses a pressure-tight closing cover, which comes pre-installed on all sealing packs, offering both water- and pressure-tight protection. The system cover allows for customized entries into the building, with pressure-tight empty conduits ready for future use.

A 150 mm diameter entry accommodates three to six lines, depending on the size of the utility lines, whether it’s for electricity, fibre optics, or other utilities. Separate closing cover are provided for each line.

Additionally, a cable protection sleeve is used in the installation, encasing the utility line for safe entry into the building. The sleeve, made of a pressure-resistant spiral tube, can endure mechanical forces up to 2.5 bar. Its smooth interior ensures the gentle installation of lines, even at a later time, without pulling.

Cable Entries for Buildings – For Empty Conduits and Utility Lines

With a clear opening of 90 mm, cable entries represent a compact and secure option for connecting empty conduits in utility systems. These conduits enable various utility lines to be conveniently and safely routed into the building, making future cable installations simple and efficient. For this reason, Hauff-Technik’s solutions are ideal for future-proofing your installations.

The Hauff-Technik system includes three essential components: the wall entry, system covers, and the cable entry system designed for the respective utility lines.

Hauff-Technik's Cable Entry System for Empty Conduits and Utility Lines

Telecommunication lines and power cables enter buildings through wall penetrations, a crucial aspect of construction. To ensure a safe and secure entry, gas- and watertight cable entries are a necessity. Hauff-Technik’s cable entry systems provide exactly that.

Each entry comes with a pressure-tight closing cover, which allows utility lines to be routed into the building. During the early construction phase, empty conduits can be installed, or cables can be directly routed. Each cap can accommodate up to six cables, providing multiple connections in a compact, space-saving manner. The bayonet system prevents the cap from accidentally opening, and Hauff-Technik allows for millimeter-precise ring seal adjustments based on customer needs.

All connections—whether for empty conduits or active lines—are pressure-tight. Unused system caps can be sealed with blind plugs for future use, allowing for easy installation of new lines. The transition between the utility line and system cap is fully gas- and watertight, and both cold and heat shrink technologies can be applied for a perfect seal.

Heat shrink sleeves include adhesive to enhance the seal. A variety of stubs are available to fit utility lines with diameters between 8 and 72 mm. The connections are gas- and watertight up to 2.0 bar of pressure.

Hauff-Technik also provides external cable protection pipe solutions. Using a sleeve system, the connection between the system cap and the protection pipe is secure and long-lasting.

The sleeves have mechanical fixings with a bayonet system, while tension nuts ensure tightness. These systems are compatible with conduits of 90 and 110 mm in diameter, with gas- and watertight transitions up to 0.5 bar between the external protection pipe and the system cap.
