General make-up of the cable
Aluminium conductor, class 2 according to EN 60228/ IEC 60228.
Cross-linked polyethylene insulation, type DIX-3 according to HD 603-1 and type XLPE
according IEC 60502-1.
The standard identification, according to HD 308, is the following:
- 1 x .................. natural
- 4 x .................. brown + black + grey + blue
Outer sheath
Polyolefin outer sheath, green colour, with low smoke and halogen free fumes under fire
Open air installation: three single-core cables in contact and ambient temperature of 30 C with adequate ventilation (supported by cleats and hangers or on perforated tray). Buried installation: three single-core cables in contact directly buried at depth of 0,7 m; 20 C of ground temperature and soil thermal resistivity of 2,5 K m/W. In all cases it is supposed a three-phase circuit. For conditions other than this apply the adequate correction factors (point 6.3). Voltage drop is the maximum that may occur. It is calculated for the maximum service temperature and for cos = 1.

Short-circuit current-carrying capacities
The maximum short-circuit current that a cable can withstand depend on the time of reaction of the protection elements installed in the line. The maximum current-carrying capacity in a short-circuit accident, for a specific type of cable, is the result of multiplying the cross section of the cable for the values shown in table 2. These values are taken from IEC 949.

Correction factors
The current-carrying capacities must be multiplied with the adequate correction factor when the installation conditions differs from point 6.1
