Medium voltage power cables in wind farms: an introduction
This post is an extension of the previous short article I wrote some years ago on the characteristics of wind farms medium voltage system. I wrote it with the help of my friend and colleague Kamran, who spent more than an hour answering my questions on the subject. Thank you Kamran! The medium voltage network…

Cable trenches layout design
We try to design cable trenches as straight as possible, avoiding pronounced angles. There are several national norms on the minimum bending angle, for instance UNE 20435/2 in Spain. For environmental and technical reasons we try to design the trench parallel to the access road. When we have to cross an obstacle such as an…

Cable trenches – the nervous system of the wind farm
Cable trenches construction probably doesn’t looks like the most exciting things in life, but including for them there are things that is better to know to avoid mistakes. They are used to connect the WTGs together with medium voltage cables, and they bring the earth and the optical fibres cables as well. The standard construction…
