Technical Tutorials and Applications

UPCOMING TUTORIAL - 22 MARCH 2012

Electrical Power Cable

COURSE OUTLINE

The following modules will be presented by Mr Dick Hardie:

How to select an electric cable (LV and MV)
• The importance of being able to carry the required full load current
• Calculation of volt drop
• Survival of fault current

PILC and XLPE cables
• The difference between these two cable types
• The costs of losses
• The danger of DC testing of old XLPE cables

Fire performance cables
• The dangers of fire spreading, toxic gas, dense smoke etc

Loading, transport and installation of electric cable

Alternative technologies for rural electrification
• Three case studies where 3.3 kV proved less costly than conventional 11kV and 400V Single core cables
• Unexpected problems caused by induced voltages or current in the metallic sheaths and armour
• How to minimize the problems, or avoid them completely by sound engineering
