Study On The Most Feasible Method For 33kV Underground Cable Installation In Urban Area Of TNB Distribution (Selangor)
Abstract
Underground distribution cable is a vital part of TNB Distribution system in delivering the required power. Selecting the most suitable cable installation method is important and it has become more difficult nowadays due to stringent requirement imposed by the passage caretaker. TNB Distribution will have to deliberately consider both requirements from TNB and the passage caretaker. This study analysed and compared various cable installation methods to select the most suitable method to fit the location criteria. The independent variables of the research consists of three major criteria that influence the cable installation methods, which are the technical effect, the practicality and the cost effectiveness. The research used a multi-model approach where the effect of the independent variables on the dependent variable, which is the method of cable installation were evaluated by a developed matrix model. The technical effect of the various cable installation method was examined using CymCap Simulation programme. The field data was used to analyse the practicality of the cable installation method to determine the best solution with respect to the aesthetic value and the strict requirement imposed by the passage caretaker. The research also studied the cost effectiveness of the cable installation methods to be adopted. The combined results determined which installation method is most feasible in the urban area of TNB Distribution (Selangor) in Malaysia.
