Customer Highlight: PEI TEL Communications
As a leading supplier of voice and data transmission equipment, PEI TEL requires specialist winding equipment we’re more than happy to supply!
Who is PEI TEL Communications?
pei tel Communications GmBH (PEI TEL) is a trusted supplier of professional voice and data equipment. And, they've been supplying the world for over three decades. For example;
- Radiating Cables,
- Loudspeakers,
- Portable Radio Devices,
- Vehicle Antennas,
- Intercoms,
- Handsets,
- Microphones,
- Body Cameras, etc.
One of those products - radiating cables - is used in mobile and indoor radio technology. To supply their customers with the right lengths of radiating cables, they use KABELMAT’s UMROL cable winders and unwinders.

A Message From the Manager of Distribution & Retail
PEI TEL’s Division Manager of Distribution and Retail - Dirk Grambke - told us some more about the business.
"If you're sitting on a train in Berlin and hear an announcement, it is usually thanks to one of our devices." "You may even hear about our devices in the US and in the Far East.”
Dirk continued on to say that PEI TEL has an extensive portfolio of wireless and infrastructure technology. It is the only German manufacturer of classic fixed-installation telephones. Because of this, the business is primarily active in Germany, Austria, and Switzerland. However, its range of products is distributed worldwide through its retail partners.
What are Radiating Cables?
In 2020, PEI TEL decided to add mobile and indoor radio technology to its product range. This meant adding components such as coaxial and radiating cables.
Also known as “leaky feeder cables”, radiating cables deliver reliable and high-frequency data coverage. For example, in tunnels, hospitals, shopping centres, and other industrial applications.
Characteristically, radiating cables have small slits or openings in the outer conductor. This lets wireless signals pass in and out. Dirk tells us more, saying; “With these cables, network providers offer scalable wireless broadband services, in larger building complexes as a preventative fire protection measure”.
KABELMAT Cable Winding Technology
HELUKABEL’s subsidiary, KABELMAT, is a specialist manufacturer of cable winding and unwinding technology. They recommended and then installed automatic winding lines. The chosen products were the UMROL 2000 unwinder and the UMROL 1800 winder. They were specifically developed to safely handle even the most delicate cables PEI TEL needs to cut.
PEI TEL’s cable is delivered on 2.5-metre-wide wooden drums, each containing the ISO standard of 2,000 metres. Dirk Grambke tells us that KABELMAT’s cable winding solutions enable PEI TEL to cut its radiating cables to the customer’s needs. It’s a service offered by very few companies but makes transporting the cable drums using small vans that much easier.
That said, PEI TEL still uses the machinery to pre-cut standardised lengths for efficiency. For example, it’s common for one customer to need 150 metres of radiating cable, while the next requires 500 metres.
Custom Solutions for PEI TEL Communications
Speaking with KABELMAT’s Sales Consultant, Manfred Wössner, he explains that they delivered high-standard custom solutions. This is because PEI TEL’s radiating cables are extremely delicate.
Throughout the discovery and matching phases, KABELMAT found that a custom solution was necessary for PEI TEL. Any alteration to the cables could impact electrical characteristics which leads to malfunctions.
Using the UMROL 2000 unwinder and UMROL 1800 winder, KABELMAT successfully adapted the contact pressure, tensile strength, operator functionality, and more. Now, only one person is needed to control the line. They use a state-of-the-art touch panel to adjust key settings and follow the process in real time.

Avoiding the Worst-Case Scenario with KABELMAT
Working with KABELMAT, PEI TEL effectively managed risks with machine calibration. The worst-case scenario is that the cables deform and are no longer usable after being wound. However, a belt length measuring device was installed to prevent deformation. It spreads the contact pressure across multiple rollers, protecting the cable.
In addition, the machines were installed with servo motors that ensure they run perfectly in sync, controlled by traction force. This is to prevent high tensile forces that not only change the length of the cable but also the shape.
Finally, it was important for PEI TEL that its cables are not excessively bent or damaged. So, KABELMAT adjusted the machines’ default settings, accordingly.
Putting Cable Winding Safety First
For PEI TEL, safety plays an important role. Safety grates, for example, were a requirement for PEI TEL to prevent employees from reaching into the machines. The company also wanted motion sensors to automatically stop the machines if a body part or object was detected inside a dangerous area.
That’s why KABELMAT was an easy choice for PEI TEL. KABELMAT’s Manfred Wössner says, "All KABELMAT machines are calibrated per the European Measuring Instruments Directive (MID) and are thus approved for use throughout Europe”.
"After everything was up and running, [they gave] intensive training and answered all questions…" says PEI TEL’s Dirk. If a problem occurs, KABELMAT technicians can remotely connect to PEI TEL’s system, initiate a diagnosis, and change parameters. This minimises downtime and contributes to operational efficiency.
Thanks to the new KABELMAT winding line, PEI TEL quickly and affordably delivers quality custom-cut lengths of its high-frequency radiating cable.
