The purpose of an electric cable is to convey electrical energy from the point where it is available, to a point where it is required. In order to do this safely and reliably, the cable needs to have certain attributes. 1. The voltage rating of the cable must be equal to, or greater than, the voltage rating of the system into which it is connected. 2. The current carrying capacity of the cable must be equal to, or greater than, the current to be carried, taking into account any applicable current derating factors. 3. The short circuit and earth fault rating of the cable must be greater than the prospective short circuit and earth fault currents that the electrical system may impose on the cable. 4. The cable must be compatible with, and able to survive, the environmental conditions in which it is installed. 5. Special attention must be paid to contributing factors such as cable voltage drop and the nature of the supplied load. 6. Each of these clauses will be discussed in further detail.

The purpose of an electric cable is to convey electrical energy from the point where it is available, to a point where it is required. In order to do this safely and reliably, the cable needs to have certain attributes.

1. The voltage rating of the cable must be equal to, or greater than, the voltage rating of the system into which it is connected.

2. The current carrying capacity of the cable must be equal to, or greater than, the current to be carried, taking into account any applicable current derating factors.

3. The short circuit and earth fault rating of the cable must be greater than the prospective short circuit and earth fault currents that the electrical system may impose on the cable.

4. The cable must be compatible with, and able to survive, the environmental conditions in which it is installed.

5. Special attention must be paid to contributing factors such as cable voltage drop and the nature of the supplied load.

6. Each of these clauses will be discussed in further detail.

Cables are made for the following voltages. 300/500V, 600/1000V, 1,9/3,3 kV, 3,8/6,6 kV, 6,35/11 kV, 8,7/15 kV, 12,7/22 kV and 19/33 kV. As well as high voltage cables from 44 kV to 275 kV.

Voltage rating

The first of the two numbers is the Phase to Earth rating, and the second number is the Phase to Phase voltage rating. Both 300/500 and 600/1000 cables are the voltage ratings typically used in the wiring up of domestic and small commercial installations.

6,35/11 kV cables are predominantly used by the municipalities and industry for the distribution of electricity.The other higher voltage ratings mentioned are less common.

Current rating

Electrical cable manufacturers’ publish tables of current ratings applicable to the size and type of cables they manufacture.

Different current ratings are applicable for cables depending on the size of the conductor, and whether the cable is installed in ground, in free air, or in a duct.

These ‘Standard’ current ratings must be modified for each unique installation by taking into account the actual conditions of installation, in particular the ambient air temperature, presence of solar radiation, the number of cables and their spacing from each other, depth of cable laying, ground thermal resistivity etc.

Standard conductor sizes are: 1,5mm2, 2,5mm2, 4mm2, 6mm2, 10mm2, 16mm2, 25mm2, 35mm2, 50mm2, 70mm2, 95mm2, 120mm2, 150mm2, 185mm2, 240mm2, 300mm2, 400mm2, 500mm2, 630mm2 , 800mm2 , 1000mm2, 1600mm2, 2000mm2 , 2500mm2.

The short circuit rating of any conductor can be calculated by reference to manufacturers’ booklets. Alternatively, the value may be calculated by multiplying the cross sectional area of the conductor by the appropriate factor. This yields the 1 second short circuit rating.

The factors for MV XLPE cable are:• Copper conductor 143 Amps/mm2

• Aluminium conductor 92 Amps/mm2

For PILC MV cables and LV PVC insulated cables:• Copper conductor : 115 Amps/mm2

• Aluminium conductors : 76 Amps/mm2

Actual figures for any particular conductor size and fault duration are available from manufacturers’ brochures.

This component carries the current, and must be of sufficiently large cross sectional area to avoid the conductor getting too hot. It may be solid circular, stranded circular, solid shaped or stranded shaped, depending on the cable specification to which it was manufactured.

Electric Cable Components

The insulation around the conductors must exhibit a high resistivity to withstand the applied voltage. It must also be able to withstand relatively high conductor temperatures before becoming soft or melting. In addition, it must be capable of being applied to the conductors using extrusion technology (paper cables are lapped not extruded). The insulation is a very important component within the electric cable and will determine the cable’s lifetime.

Certain cable constructions require a layer of bedding under the armour layer. It’s purpose is to protect the underlying components during the armouring application, by providing a soft layer on which the armour can be applied without damage to the underlying cable components. It is probably the least important component within the cable, but its thickness and material quality are nevertheless stipulated in the cable specification. Normally PVC (Polyvinyl chloride) is used with fire retarding properties.

Armouring may consist of SWA (Single Wire Armour, sometimes called Steel Wire Armour), AWA (Aluminium Wire Armour) or steel tape armour. Galvanized steel wire has many advantages over steel tape, and is the most commonly used. The armour protects, or minimises damage to the underlying components from external impact. Importantly, SWA provides the cable with better tensile strength, which is important if ground movement is likely to occur.

The cable outer sheath protects it from the ingress of moisture and provides overall mechanical protection; weather, chemical and electrical. PVC is commonly used and is very satisfactory for most applications.
