Investigation and test methods specific for medium and high voltage power cable insulation
Methods of testing polymer cable insulation for electrical and electrochemical ageing resistance are described. The degree of ageing is estimated using a microspectral analysis. Procedure and device for polyethylene insulation “life curve” test are described. Examples of insulation structure influence on its quality are given.
Power cable, cross-linked polyethylene, ethylene-propylene rubber, water tree, electrical tree, life curve, structure.
