H1Z2Z2-K 1x16 1,5 kV DC
IEC nominal calculation, not manufacturer data. The thicknesses are the nominal values of the construction standards, added up layer by layer. A manufacturer's cable of the same name can differ by a few millimetres and by 10 to 20 % in weight: always check its datasheet before you specify, order or lay a cable.
By the IEC construction rules, H1Z2Z2-K 1x16 1,5 kV DC comes to an overall diameter of about 8.3 mm and a weight of about 200 kg/km.

| Diameter over insulation | 6.5 mm | |
| Overall diameter | 8.3 mm | |
| Weight (approximate) | 200 kg/km |
Round conductors (IEC 60228 class 2 compacted; class 1 solid up to 10 mm²).
Layer by layer (inside out)
| # | Layer | Material | Thickness mm | Ø over mm | Source | How firmly |
|---|---|---|---|---|---|---|
| 1 | Insulation | Halogen-free (LSZH) | 0.7 | 6.5 | EN 50618:2014, Table 1, p. 14 | read in the standard |
| 2 | Sheath | Halogen-free (LSZH) | 0.9 | 8.3 | EN 50618:2014, Table 1, p. 14 | read in the standard |
H1Z2Z2-K is the EN 50618 code (HD 361 system), not a VDE name: the insulation and sheath are the walls of EN 50618 Table 1, and the overall diameter must stay within its maximum. Sources and page numbers: research/mv-dimensions in the site repository.
Weight, by part
| Conductors | 150 kg/km |
| Metal screens and armour | 0 kg/km |
| Insulation, semicon, tapes, fillers and sheaths | 50 kg/km |
| Total | 200 kg/km |

Each layer's cross-section times its density; stranded conductors, laid-up cores and helical wires count 2 % longer than the cable. Densities: copper 8.89 and aluminium 2.703 g/cm³ (the values of IEC 60028 and IEC 60889); XLPE 0.92, PE 0.94, PVC 1.45, semicon 1.12, steel 7.85 g/cm³ (usual compound values).
H1Z2Z2-K 1x16 1,5 kV DC: equivalents in other countries
Shown for 1x16 1/1 kV. Each country's rules are applied to this build, keeping the conductor, section, cores, voltage, screen, armour and sheath.
| Country | Standard | Name in that country | Verdict | Differences |
|---|---|---|---|---|
| International (IEC) | IEC 62930 | 62930 IEC 131 1x16 1,5 kV DC | Close | this cable as built misses 1 of its rules |
Nominal values computed by each standard's rules, not manufacturer data. This is not a statement that two cables are interchangeable: the buyer's specification and the maker's type test decide.
