Elektrizitätswerk Dietlikon are the first regional utility known to use 5-core underground cables for the new-built, extension and repair sectors. The cable has 3 phase conductors made of aluminium, 1 neutral conductor of equal cross section but made of copper for coping with the potential harmonic currents and a copper screen used as PE conductor. This was the best compromise that could be achieved in negotiations with the cable maker who first wanted to use only aluminium.

To put high-voltage cables underground is expensive, but can produce many benefits. The choice of overhead lines versus underground cables has many issues to consider besides cost, such as system reliability, transmission losses, amenity effects, preservation of natural and cultural heritage, lifetime cost, land use, property value, health and psychology of citizens living near lines, planning delays, and end-of-life.
This new eBook, in partnership with Europacable, gives an overview of pros and cons of underground power cable, looking at the whole picture.

Underground High Voltage Cables: Wiring Europe for the Future
In many of Europe's largest cities and in areas where construction of overhead transmission lines creates difficulties, high and extra-high voltage underground electricity cable systems rated 220kV and above have become part of the backbone of modern day power transmission infrastructure. Although cables have been in use for over half a century, today's underground high voltage cables are leveraging state-of-the-art technology and advanced design to expand their reach and are increasingly becoming an efficient and reliable alternative to overhead lines. Underground high voltage cables are powering a changing world.
This eBook presents the main benefits of underground high voltage cables:
