Cable duct system Hateflex

Combining flexibility & impact resistance

Over the course of its life, a building frequently undergoes renovation, refurbishment or change of use. In most cases these activities only take place in the parts of the building located above ground level. Nonetheless, the requirements for the power infrastructure in a building can also change significantly over time.

This is where it is recommended to use cable ducts to reduce the required earth moving to a minimum. Cable ducts allow new cables to be installed or old ones to be replaced without having to move a lot of earth. Cable ducts contribute to a sustainable infrastructure for the future.

The Hateflex is a polymer cable duct with a smooth inner surface. The combination of hard and soft PVC gives it the properties of flexibility and impact resistance. The cable duct system is available in 5 sizes and provides watertightness up to 2.5 bar.

Reduce the total cost of ownership

The need for a flexible and impact resistant cable duct for connecting buildings is an important step towards saving resources in the future due to possible new installations or renovations. The Hateflex combines the flexibility and impact resistance in one. The installation time can be reduced by laying 25 m long individual lengths. For longer distances, fewer connections are required than with the common single pipe length of 6 metres.

In combination with the Hauff-Technik cable entries, Hateflex forms a coherent cable entry system with gas and watertightness of up to 2.5bar. Savings during installation stage and later during a renovation reduces the total cost of ownership.

Advantages of our ducting system

Reduced installation time

Single lengths of up to 25m are possible, thereby reducing installation time. If longer distances are required, fewer connections are needed.

Easy installation

Easy to install watertight length extension using watertight connection sleeves.

Watertight adaption

Watertight adaptation to other Hateflex sizes possible by using connection sleeves with adapters.

Peak compressive strength according to DIN EN 61386-24

An important property of cable hoses is their mechanical load capacity. This is calculated and classified according to the pressure test described in DIN EN 61386-24. The test describes the maximum vertical force that needs to be exerted on the pipe apex for its inner diameter to be deformed by 5%.

Hateflex combinations

Hateflex can be combined with the wide Hauff-Technik cable entry portfolio. On the one hand a combination of Hateflex and wall inserts is possible with the use of HSI system covers or preinstalled sleeves like the foldable sleeve HSI KMA or BWS KMA.

For retrofit installations the KES KB system can be used to connect the different sizes of the Hateflex. The KES system also includes the connection sleeves to extend the length or reduce the size.

Other combination options according to application

Pressure tightness up to 0.5 bar

The HSI150 KMA WR can be used for connecting conventional corrugated pipes. With this cable entry system, the pressure-tightness depends on the corrugated pipe, but is generally up to 0.5 bar.

Pressure tightness up to 0.5 bar

At a required pressure-tightness up to 0.5 bar, the HSI150 GSM can be used for the connection of smooth cable ducts. An HSI150 DG system cover is installed on the inside of the building for cable sealing.

Pressure tightness up to 1 bar

At a required pressure-tightness up to 1 bar, the Hauff-Flex 150 cable duct hose can be used. Connection to the building is via HSI150 KMA. An HSI150 DG system cover is installed on the inside of the building for cable sealing.

Pressure tightness up to 2.5 bar

For a cable entry system with a pressure-tightness up to 2.5 bar, use the Hateflex14150 cable duct hose. The connection to the building is via the HSI150 KMA, cable sealing on the inside of the building with an HSI150 DG system cover.

Tips on installation

The pipe trench should be excavated to the necessary depth; the trench bottom must be compressed in such a way that subsidence is ruled out.

The trench bottom should be levelled free of stones and kept free of foreign bodies. A sand bed of approx. 10 cm should be added.

The Hateflex hose system should be covered with 10 cm of sand and compressed by hand. The remaining pipe trench should be filled in 30-cm layers with stone-free fill material and compressed.

If more than two hoses are being installed, connect the spacers together.

Slot the eyelet onto the pin for this purpose.

In the first layer, place the spacers directly on the soil and clip in the hose.

Fill up space between and next to the pipes and compress.

In the case of multi-layer hose systems, the spacers are placed on the layer of hoses immediately below. The hoses can then be clipped in again.
