Photovoltaic cables

  • Photovoltaic cablesState-of-the-art  1.5 kV DC cross-linked ENERGYFLEX® cables offer exceptional performance, easy installation and long-term reliability for short DC connections.
  • Resistant to extreme temperatures (-40°C to +120°C), ozone and UV, these zero-halogen cables are low-smoke and flame-retardant for enhanced fire security.
  • ENERGYFLEX® is fully compliant with the applicable photovoltaic cable standard: EN 50618:2014
  • Through its multiple plant capacity, Nexans is able to provide them anywhere in the world. At its Nexans Research Center, Nexans tests Energyflex® in especially harsh conditions.

Nexans supplied Schneider Electric with over 1,000 km of Energyflex® photovoltaic cables in a mere two-and-a-half months for a photovoltaic farm in Sanpietro Vernetico, near Brindisi, Italy.

We also provided Eiffage with over 3,000 km of Energyflex® photovoltaic cables for the gigantic Cestas solar farm. These cables are used to interconnect panels, and to connect module strings to the inverter.

These cables are part of our Keylios™ solutions designed by Nexans to respond to the very demanding expectations of the photovoltaic market.

Cavi d'uso industriale/Cavi per impianti fotovoltaici


KEYLIOS® Energyflex® PV H1Z2Z2-K Cable (1.5kV DC)
Cavi d'uso industriale/Cavi per impianti fotovoltaici
Energyflex® cables are designed to comply with the international standards of the solar plants.
They are dedicated to the photovoltaic system direct current (D.C.) side with a nominal D.C. voltage of 1.5 kV and a maximum D.C. voltage of 1.8 kV.
These cables are suitable for permanent outdoor long-term use, under variable and harsh climate conditions. They are designed and tested to operate at a normal maximum conductor temperature of 90°C and for 20,000 hours up to 120°C. Therefore, the expected period use is 30 to 40 years under normal usage conditions (lifetime acc. to Arrhenius-Diagram).
KEYLIOS® Photovoltaic Harness
Cavi d'uso industriale/Cavi per impianti fotovoltaici
Nexans designs, produces and installs complete Harnesses for the Photovoltaic Farm.
