SYNOPSIS

PART I
Power cables are important component in energy delivery system. In depth understanding of its design & construction, installation, O&M as well as failure or fault analysis will ensure safe operation and improve reliability of the supply system. This talk will cover the following topics :- cable design and construction, cable application, selection, and specification, underground cable installation, cable ampacity ratings, jointing and termination standards and practices, commissioning & in service maintenance testing, cable failure modes and Faults analysis on cable.

PART II
Electrical connections come in two forms – end terminations and joints between two conductors. A good electrical connection is one that is able to conduct current safely at a low temperature, resulting in energy savings and should last for many years. But how can you ensure and achieve a good electrical connection every time? This section covers important factors in executing a good electrical connection, with actual cases of applications. Relevant Malaysian Standards will also be discussed. Lastly the talk will also cover cases involving less common terminations, by evaluating different types of critical connections and recommended procedures.
