Alliander

Network company Alliander, formerly known as electricity production and supply company Nuon, handles the distribution of energy in one third of the Netherlands. Liandon, a part of Alliander, is engaged in construction and maintenance of energy infrastructure. A publically known part of this is the grid of overhead power lines by use of high voltage masts. The application of a high voltage mast today is multiple. Next to carrying the transmission lines for the transport of electrical power it is also used as a carrier for mobile telecommunications network antennas. Then there is the use of transporting digital data through the lightning wire. For this technique the lightning conductor cable contains optical fibers in the center of the ground wire (OPGW - optical power ground wire).

Fortan was involved in the construction of a 56m mast in the 220 kV circuit Louwsmeer-Oudehaske and a 28m mast in the 150 kV circuit Nijmegen-Zevenaar-Langerak. For the mast design, modeling, and manufacturing drawings of both types of masts Tekla Structures was used. Conventional Acad 2-D was used by Fortan to contribute to various enhancements onto masts and gantries. There were conductor accessories, OPGW accessories and cabinets, platforms, climbing and fall protection systems, building permit drawings.
