Abstract

Nowadays, electricity is very vital to all mankind after water. Most of our daily work includes the using of electricity. Usually, the underground medium voltage (MV) power voltage will be used in distributing the electricity to the consumer by Tenaga Nasional Berhad (TNB). A single core MV power cable consists of three major components. They are conductor, insulation, and a protective jacket. Presently, TNB has it's own standard in selecting the suitable and the exact size of the underground cable. Cables are usually selected based on their ampacity or current carrying capacity. However, there are some parameters that influence the cable ampacity such as soil thermal resistivity, depth of cable laying, ambient temperature, methods of cable installation and cable size and dimensions. Thus, this project proposes to design and analyse the single core MV power cables using the ANSYS Maxwell software. Then, the cables will be analysed in term of ampacity using Finite Element Method (FEM). The analysed result then will be tabulated and presented in graphs. After that, the comparison between the standards from the Institute of Electrical and Electronics Engineers (IEEE) and International Electrotechnical Commission (IEC) and the result from this project will be conducted to ensure the compatibility and validity of the analysed result.
