Electron Beam Cross-Linking: An Emerging Technology for Processing Electrical Wires, Cables and Accessories

Polymers are extensively used in various power engineering applications for its excellent dielectric and mechanical characteristics. Electron beam technology lends further support for expanding the application of polymers in power engineering. The use of electron beam cross-linking of polymers in preference to the conventional chemical cross-linking processes has several advantages. This paper discusses the advantages of this technology with particular reference to power cable and accessories for termination and joints. The improvements in dielectric, mechanical and thermal characteristics are emphasised to highlight the need for increasing the use of this technology for critical power engineering applications.
