Application


These power cables are used for electricity supply in low voltage installation systems.

The cables are fully complyin to IEC and SEC, 1-SDMS-01, Rev.02 from KSA.

They are well adapted to underground use in industrial applications where chemical and mechanical protections are needed (refinery areas, chemical plant…)
