VG-YMvKas Dca ALU
Power cable 0.6/1 kV, aluminium conductor, armoured
VG-YMvKas Dca ALU is the aluminium version of the armoured underground cable: aluminium conductors, XLPE insulation, galvanised steel wire armour with earth continuity conductor (GSWA+ECC) and a flame-retardant PVC sheath in reaction-to-fire class Dca, Cca on request. For long routes and large cross-sections, where the weight and copper price of the copper version are major factors.
Armoured power cable with aluminium conductors for 0.6/1 kV, for low-voltage installations to NEN 1010. Suitable for direct burial, also in wet soil but not directly in water, and for installation above ground, for example as a supply cable for main and sub-distribution boards where mechanical protection is needed. The aluminium conductors keep the cable light. Available with three and four cores from 35 to 300 mm².
Also known as: aluminium underground cable
Applications
- Underground distribution over longer distances on business parks and in infrastructure.
- Low-voltage connections of solar parks, charging plazas and transformer stations.
- Underground supply cables to buildings. If the specification calls for Cca, we supply that version on request.
What to look out for
- Aluminium: terminate with bimetallic lugs or terminals approved for aluminium, clean and grease the contact face. Aluminium directly on a copper busbar corrodes.
- The same current needs one to two steps more cross-section than copper: aluminium 4×150 mm² corresponds to copper 4×95 mm².
- For the same current, a larger outer diameter and bending radius than the copper VG-YMvKas: check entries, glands and bends in the route accordingly.
- Connect armour and earth continuity conductor together as the earth path, at both ends.
- Conductor
- Stranded aluminium, class 2 acc. to IEC 60228, sector-shaped.
- Insulation
- Cross-linked polyethylene (XLPE).
- Inner sheath

- Armour

VG-YMvKas Dca ALU or AL/AL?
VG-YMvKas Dca ALU
- galvanised steel wire
- copper wire earth conductor (ECC)
VG-YMvKas AL/AL
- round aluminium wires
- earth via the armour
Both have aluminium conductors, XLPE insulation and no green/yellow core. The difference is the armour, and with it the earth. VG-YMvKas Dca ALU has galvanised steel wire with an earth continuity conductor of copper wires (ECC); on VG-YMvKas AL/AL the armour of round aluminium wires carries the earth itself. If you want to connect the earth to copper, choose the Dca ALU; with AL/AL the glands must also be suitable for aluminium.

VG-YMvKas Dca ALU
- aluminium conductors
- terminals approved for aluminium
VG-YMvKas Dca
- copper conductors
- connects directly to copper terminals
Armour with earth continuity conductor (GSWA+ECC), XLPE insulation, PVC sheath and CPR class Dca-s2,d2,a3 are the same; the main difference is the conductor. Aluminium is lighter and more economical, but needs a larger cross-section for the same current and bimetallic lugs or terminals approved for aluminium. Aluminium pays off mainly on long routes and in large cross-sections; copper connects directly to copper terminals.
