According to experienced utility engineers, many organizations initially adopted easy-strip screens to reduce installation time and minimize workmanship issues at medium voltage levels. However, as bonded screen stripping tool technology has advanced, particularly with the introduction of precision instruments that eliminate the need for lubrication and provide chamfered cutbacks, there has been movement toward bonded screens even at lower voltage classes.\n            <span class=\"chinese-explanation\">\u884c\u4e1a\u4e13\u4e1a\u4eba\u58eb\u89c2\u5bdf\u5230\u8fc7\u53bb\u51e0\u5341\u5e74\u4e2d\u534a\u5bfc\u7535\u5c4f\u853d\u5c42\u6280\u672f\u504f\u597d\u7684\u663e\u8457\u8f6c\u53d8\u3002<\/span><\/p>\n\n            <p>Ben Lanz, Director of Applications Engineering at IMCORP USA with expert technical oversight of power cable life cycle consulting for systems ranging from 5kV to 500kV, emphasizes that the semi-conductive screen cutback represents the most critical point in cable termination procedures.
