Objectives Research The objective of this project is to be able to provide assurance to National Grid, that cables that experience a higher loading, and therefore run hotter (up to 105 degrees) due to increased loading will not experience any unknown or unexpected mechanical effects and therefore will not have shortened life expectancy or unexpected failures. This project will be successful if the cables are modelled successfully at operating temperatures agreed with the suppliers. A further success would be if National Grid could implement an increased ratings recommendation based upon this work (this would need to be complemented by other work). This project will therefore be successful if we increase our level of knowledge on the behavioural aspects of heated cables.
Abstract National Grid has a problem understanding the magnitude of thermo-mechanical effects of large cross-section cross linked polyethylene (XLPE) cables. This problem leads to particular difficulties in designing the steel support work where cables meet gas insulated substation (GIS) and air insulated substation (AIS) terminations. It is currently suspected that they are over engineered. Through testing of cable samples in differing conditions, we will be able to create a model that allows us to have an increased understanding of the Thermomechanical forces in XLPE cable systems. We will be researching methods of calculating / measuring the thermo-mechanical forces imposed when a cable is in service, and possible methods of eliminating them. This will be achieved by physical testing and the use of Finite Element Analysis.Note : Project Documents may be available via the ENA Smarter Networks Portal using the Website link above
