A LIFE CYCLE ANALYSIS STUDY OF COMPETING MV CABLE MATERIALS Simon Sutton Dow Chemical Company Ltd, UK [email protected] ABSTRACT A simple life cycle cost model has been developed to investigate the total cost of ownership for three competing MV cable designs; XLPE, water tree retardant XLPE (TR-XLPE) and EPR. The high level factors influencing line protection include the criticality of the line (in terms of load transfer and system stability), fault clearing time requirements for system stability, line length, the system feeding the line, the configuration of the line (the number of terminals, the physical construction of the line, the presence

Single Line Diagram of 11kV Substation Substation provides the energy supply for the local area in which the line is located. The main function of the substation is to collect the energy transmitted at high voltage from the generating station and then reduce the voltage to an appropriate value for local distribution and gives facilities for switching. Aug 24, 2011 · When there is a dead end of the line or there is corner or sharp curve, the line is subjected to greater tension. In order to relieve the line of excessive tension, strain insulators are used. For low voltage lines (< 11 kV), shackle insulators are used as strain insulators. 'Distributor' is a line from which tappings are taken along its length to provide supply to various consumers. The distributor is supplied from a distribution sub-station where a high voltage (11 KV) is stepped down to a much lower distribution voltage (415V and 240V) for domestic, commercial and industrial use. structure /line material covered under the Contract for the purpose other than the contract awarded. 8.2 In an event of any material used for transmission line found broken or damaged or received short during transit or failed during the erection/ testing at site before commissioning of line, the Contractor shall replace the same free of cost.
