This article focuses on a range of elements critical to this process; form the fundamental chemistry, through computational and measurement techniques to the solutions that are in use today. Degassing contributes greatly to the quality of power cables by improving the certainty in electrical testing and improving the dielectric properties. To ensure that the degassing process delivers the expected benefits, it is important to measure and model the process by which the crosslinking byproducts are desorbed from the cable polymers. Weight loss and HPLC have shown themselves to be the most effective and practical measurement techniquesread more

Breakdown statistics for XLPE containing the volatile by-products of the cross-linking reaction
TL;DR: In this article, the breakdown strength of recessed samples of cross-linked polyethylene (XLPE) containing the by-products of the crosslinking reaction was investigated. But, despite the fact that a simple weakest link mechanism cannot be used to describe the breakdown strengths, no reason has been found to discard the Weibull distribution.
