Title:
FORMULA DESIGN AND OPTIMIZATION METHOD FOR CROSSLINKED POLYETHYLENE INSULATING MATERIAL OF HIGH-VOLTAGE ALTERNATING-CURRENT CABLE
Document Type and Number:
WIPO Patent Application WO/2024/045336
Kind Code:
A1
Abstract:
The present application relates to a formula design and optimization method for an XLPE insulating material of a high-voltage alternating-current cable, comprising the following steps: Step 1, determining initial formula elements, comprising types of base resins, antioxidants and cross-linking agents; Step 2, testing a sample prepared by performing hot press molding on a pure base resin, and preferably selecting on the basis of a qualitative evaluation index I and a quantitative evaluation index I sequentially to obtain a preferred base resin; Step 3, preparing a plurality of groups of cross-linking agent/antioxidant/base resin blends, and preferably selecting on the basis of a qualitative evaluation index II and a quantitative evaluation index II sequentially to obtain an optimized cross-linking agent formula; Step 4, preparing a plurality of groups of cross-linking agent/antioxidant/base resin blends, and preferably selecting on the basis of a qualitative evaluation index III and a quantitative evaluation index III sequentially to obtain an optimized antioxidant formula; and Step 5, verifying electrical performance, and when test result parameters all satisfy requirements, taking the material formula as an optimized formula, or otherwise returning to test alternative materials under test.
