Title:
CROSS-LINKED POLYETHYLENE CABLE INSULATION MATERIAL RELIABILITY PREDICTION METHOD
Document Type and Number:
WIPO Patent Application WO/2023/179043
Kind Code:
A1
Abstract:
A cross-linked polyethylene cable insulation material reliability prediction method comprises the following steps: step 1, carrying out cross-linking reaction on a plurality of groups of crosslinkable materials, so as to obtain a plurality of groups of cross-linked polyethylene and enthalpy values of the plurality of groups of crosslinkable materials at exothermic peaks of the crosslinking reaction; step 2, carrying out a thermal extension experiment on the plurality of groups of cross-linked polyethylene, so as to obtain load elongations of the plurality of groups of cross-linked polyethylene; step 3, on the basis of the enthalpy values of the plurality of groups of crosslinkable materials at the exothermic peaks of the crosslinking reaction and the load elongations of the plurality of groups of cross-linked polyethylene, establishing a cross-linked polyethylene cable insulation material reliability prediction curve; step 4, carrying out cross-linking reaction on a crosslinkable material to be predicted, so as to obtain an enthalpy value of said crosslinkable material at an exothermic peak of the crosslinking reaction; and step 5, comparing the enthalpy value of said crosslinkable material at the exothermic peak of the crosslinking reaction and a standard enthalpy value, the crosslinkable material being a cross-linking agent and polyethylene.
