Portuguese MV Cables

With its own distinct cable nomenclature, specifying Medium Voltage cables in Portugal or for Portuguese projects can be challenging unless you understand the references used. 

Our Portuguese MV Cables are manufactured in accordance with IEC 60502-2 and generally in accordance with harmonised document HD620-10L. They cover voltage ratings of 3.6/6 kV, 6/10 kV, 8.7/15 kV, 12/20 kV and 18/30 kV.

Understanding Portuguese Cable Nomenclature

The table below explains the specific letters and numbers as they relate to the constructional elements and materials used. It should be noted that under HD620 10L, there is only one option for insulation materials: XLPE (Cross-linked Polyethylene) - hence it not being separately designated below.

It follows that the only sheathing material suitable for a cable holding a CPR classification of Cca is the Low Smoke Zero Halogen compound, therefore the suffix 'frt' will only accompany a cable holding the Z1 designation.

Specifying Portuguese MV Cables

Our team of Portuguese speaking cable and industry specialists, alongside our team of technical experts from The Cable Lab, can support specification against Portuguese references. This includes providing evidence and explanation for cross-border comparisons in order to aid integration into existing power distribution networks or support procurement for urgent requirements. 

Details of the electrical characteristics, and cable dimensions (to aid sizing for cable accessories) are included on the technical datasheets linked below. Where additional electrical data or information for installation design is needed, this can be provided on request.
