Statistical distribution analysis of rubber fatigue data

A v e r a g e rubber fatigue resistance has previously been related to such factors as elastomer type, cure system, cure temperature, and stress history. This paper extends this treatment to a full statistical analysis of rubber fatigue data. Analyses of laboratory fatigue data are used to predict service life. Particular emphasis is given to the prediction of early tire splice failures, and to adaptations of statistical fatigue analysis for the particular service conditions of the rubber industry.

Water contamination in a cross-linked polyethylene cable joint

An analysis of splice failures on a cross-linked polyethylene (XLPE) insulated cable is performed with particular interest in the effects of contaminants and the adsorption of water on surface track resistance of the splice pencil. Many cable users do not give sufficient consideration to the hygroscopic nature of XLPE surfaces when developing splicing procedures. This paper examines some of the effects of water on XLPE cable joints and presents procedures to eliminate its detrimental effects.
