SUMMARY
This study evaluates the reliability of submarine power cable 20 kV Bangka-Lepar. The Submarine power cable also describes the medium voltage distribution network at Bangka-Lepar and determines the correlation of various parameters that affect network operations and then provides information about the power cable itself and laying procedures. Furthermore the research conducts with reliability analysis based on statistical models. This model is used to evaluate characteristics operational cable such as failure rates of natural or human causes, and is also used to choose between two cable routes and to determine one maximum reliability
