Get sporty

Lapp cable products are in demand in large sporting facilities. From energy chains to solar cabling, Lapp products can be found in the homes of champions worldwide.

The 13,500-seat Fenerbahçe Ülker Sports Arena in Istanbul boasts the largest display system in Europe. Measuring 8 x 8 x 10 m, the screen was installed in 2012. The ‘floating’ display cube offers a total of 280 m² of screen surface area. Depending on the event, the 32-tonne system can be lifted and lowered and presents up-to-date information. Lapp Kablo Turkey, working together with UI Lapp GmbH and Brevetti, planned a 28.5 metre-long Silvyn Chain power chain, weighing 415 kg. The Silvyn universal range completely protects cables against dust, moisture and technical, thermal or chemical exposure.The versatile Silvyn Chain range of energy supply chains also protect and guide cables in dynamic applications.

Europe’s largest display system.

The basic model which would typically be used for this type of application is the robust heavy-duty SR909B power chain, with triple connecting pins. For this project, however, a special basket was constructed, in which the chain was ‘embedded’ after being lifted. In the power chain itself, screened Ölflex FD Classic 810 CP, Ölflex FD 855 CP and Ölflex FD 90 CY connecting and control cables ensure reliable connections between the three control panels in the scoreboard and the central console under the roof.

Not confined to indoor sports, Lapp Systems has also been working on solar for stadiums. At the Signal Iduna Park in Dortmund, Germany, a total 8800 thin-film solar modules were installed on the roof with a total power of 924 kWp. To provide a reliable connection for the modules, the company produced four-way Y-array harnesses, which were fitted with separate, integral and pluggable overload current fuses at the request of the customer.

On the four-way array harnesses, the distance between the coupling points is 10.6 m and the branch is just 20 cm long. The extruded overload current fuse is simply attached to the string and thus connected to the panel series. A total of 160 array harnesses and 640 extruded fuses were installed with 6 km of Ölflex Solar XLR cable.

At Erdgas Sportpark in Halle, Germany, 5094 SE thin-film modules with an output of 535 kWp were installed. For this project, Lapp Systems produced three-way double-Y array harnesses with integrated overload current fuses.

In general, the array harnesses can be produced in a T, Y or double-Y design. The number of strings can be increased depending on the cable cross-section. The electron beam cross-linked Ölflex Solar XLR cable is used. It benefits from particularly high thermal and mechanical resistance and is TÜV-type approved. Weather and UV-resistant polyamide resin is used for the extrusion.

The Lapp cabling solutions bring tangible benefits: thanks to the use of array harnesses, up to 60% fewer solar cables are required between the modules and the inverters - which means material costs are significantly reduced. Furthermore, the plugged-in, separate fuses facilitate maintenance and repair.
