Cablowind: for certified and maximised resistance
Enter Cablowind: concrete channeling available in three sizes that further ballasts the PV system. Cablowind is a dual-purpose Sun Ballast accessory. It increases and optimises the entire PV plant’s wind resistance and allows for proper cable housing, ensuring a clean and tidy system with cables protected from external stresses.
Cablowind, as you can see from the video, is installed on the back of the ballast, which is already drilled, through the use of special bracket made of zinc magnelis, a material that is highly weather resistant (much more so than aluminium.)
In addition, the channel, made entirely of concrete, does not change over the years, and like all Sun Ballast ballasts is guaranteed for up to 25 years.
In addition to simply connecting the ballasts like a bar, Cablowind also has a function from a static point of view. With its insertion on the ballasts, a genuine increase in the strength of the entire system was noted, thanks to the fluid dynamics tests to which the component was subjected.
A further difference between the bars and Cablowind is the type of weight used. The weight placed on the bars was a type of point weight that therefore focused the weight load at a small point on the surface, the weight of Cablowind, on the other hand, is well distributed and therefore does not overload a single point on the roof.
Bars Vs Cablowind
Ultimately, after careful calculations and evaluations (see below), we came to the conclusion that, net of all the advantages and objections, evaluating only the cost/benefit factor: for the same wind resistance, the cost per Kw of a system using Cablowind is significantly lower than a system made using bars. Not only that, but also the strength resulting from the use of Cablowind is significantly higher than that of an installation using bars.
