Underground Cables / Overview over Copper and Aluminium Cables

Underground cables from the vendor

Underground cables are power or communications cables that are layed underground. The cable coating is especially robust in order to avoid the cables' destruction from animals or due to chemical influences.

Underground CableUnderground cables are layed within a layer of sand, in order to avoid damaging the cable coating when weight is put onto the ground. Above the sand layer usually a trench warning tape is being layed, in order to warn an excavator in time before the cable is damaged. In order to protect the cable from frost, it's being layed in a safe depth of at least 60cm.

We offer underground cables as power cables of the type NYY for example. These cables exist as NYY-O (underground power cable without ground wire) and NYY-J (underground power cable with ground wire). We offer underground power cables with copper conductors and with aluminium conductors. Copper has a better conductivity than aluminium. That is why copper underground cables require a smaller cross-section (about 1.65) than aluminium underground cables to conduct the same current. Besides power cables, we also offer control cables and data cables like telecommunications underground cables.

Here at Lieske-Elektronik you will find a broad selection of underground cables. The most common underground cables are usually available directly from the cable vendor. That is why we can serve all orders very quickly. The prices shown on the product pages are usually prices per meter including the daily updated copper surcharge. It always applies the copper price from the day of the order. The copper price is shown seperately for each article.

For products that are sold by the meter you can order underground cables in any desired length. If you need several parts with different lengths, please tell us when you order. If we have the desired length in stock, there will be no charges for cutting. For underground cables that are not in stock, the cable vendor charges a cutting fee of 10,- EUR net.
If larger cables drums are required for an order, we use rented drums, that have to be returned after a certain amount of time. If you wish, we can also deliver directly to the construction site.

Please choose from one of the four following underground cable types. If you need a type of cable that you can't find here, please give us a call. We are happy to help you out. Hotline: +49-7666-88499-0.
