Nexans XLPE-HDPE TR AL 15kV 1x300mm2

Application:

The use of bare conductors in overhead power distribution lines, especially in wooded areas, leads to frequent disconnections due to the possible contact of branches with the conductor. This is because the conductor has no protection and is totally exposed to the environment, which is why maintenance interventions are frequent, causing inconvenience to the population.

With the aim of improving the quality of energy distribution, Nexans offers the Nexans XLPE-HDPE TR AL medium voltage cable range for use in compact aerial distribution networks.

Nexans XLPE-HDPE TR AL cables enable greater reliability in the supply of electricity, reducing corrective maintenance and unexpected power outages, as well as harmonious coexistence with the environment, drastically reducing tree pruning and minimizing visual pollution of the environment.
