What is HD620 Standard Cable?
HD620 harmonization document represents a comprehensive European standard for medium voltage power distribution cables with extruded insulation. Officially titled “Distribution cables with extruded insulation for rated voltages from 3.6/6 (7.2) kV up to and including 20.8/36 (42) kV,” this standard was developed by CENELEC (European Committee for Electrotechnical Standardization) to ensure uniformity and quality across European power distribution networks.
According to authoritative industry sources, the latest iteration HD620 S3 was released by CENELEC and ratified by member countries in 2023. This standard is commonly linked to German Standard DIN VDE 0276 Part 620 and has been adopted nationally across Europe, including UNE-HD 620 in Spain, NEN-HD 620 in the Netherlands, CEI-HD 620 in Italy, and DS-HD 620 in Denmark.
