For example, specifications commonly state &#8220;Class 5 tinned annealed circular copper conductor per IEC 60228 and AS\/NZS 1125.&#8221; This dual reference isn&#8217;t redundant but rather confirms the harmonized nature of the standards.

In surface mining operations, cables undergo constant flexing as mobile equipment moves across uneven terrain, combined with the mechanical stress of coiling onto cable reels during equipment repositioning. Class 5 conductors, with their fine-strand construction typically featuring individual wire diameters between 0.21mm and 0.51mm depending on the overall conductor size, can endure tens of thousands of bending cycles without strand breakage or work-hardening.<sup>[18][19]<\/sup><\/p>\n                <span class=\"chinese-note\">IEC 60228 Class 5\u5bfc\u4f53\u7684\u67d4\u8f6f\u6027\u7279\u5f81\u4f7f\u5176\u7279\u522b\u9002\u5408Type 441\u7535\u7f06\u5e94\u7528\u7684\u673a\u68b0\u8981\u6c42\u3002\u5728\u9732\u5929\u91c7\u77ff\u4f5c\u4e1a\u4e2d\uff0c\u968f\u7740\u79fb\u52a8\u8bbe\u5907\u5728\u4e0d\u5e73\u5766\u5730\u5f62\u4e0a\u79fb\u52a8\uff0c\u7535\u7f06\u4e0d\u65ad\u5f2f\u66f2\uff0c\u52a0\u4e0a\u8bbe\u5907\u91cd\u65b0\u5b9a\u4f4d\u671f\u95f4\u5377\u7ed5\u5230\u7535\u7f06\u5377\u7b52\u4e0a\u7684\u673a\u68b0\u5e94\u529b\u3002Class 5\u5bfc\u4f53\u5177\u6709\u7ec6\u80a1\u7ed3\u6784\uff0c\u5355\u7ebf\u76f4\u5f84\u901a\u5e38\u57280.21mm\u81f30.51mm\u4e4b\u95f4\uff08\u53d6\u51b3\u4e8e\u6574\u4f53\u5bfc\u4f53\u5c3a\u5bf8\uff09\uff0c\u53ef\u4ee5\u627f\u53d7\u6570\u4e07\u6b21\u5f2f\u66f2\u5faa\u73af\u800c\u4e0d\u4f1a\u51fa\u73b0\u80a1\u7ebf\u65ad\u88c2\u6216\u52a0\u5de5\u786c\u5316\u3002<\/span>\n\n                <div class=\"table-wrapper\">\n                    <table class=\"data-table\">\n                        <thead>\n                            <tr>\n                                <th>Application Scenario<br>\u5e94\u7528\u573a\u666f<\/th>\n                                <th>Conductor Class Requirement<br>\u5bfc\u4f53\u7b49\u7ea7\u8981\u6c42<\/th>\n                                <th>Bending Cycles Expected<br>\u9884\u671f\u5f2f\u66f2\u5faa\u73af<\/th>\n                                <th>Typical Cable Configuration<br>\u5178\u578b\u7535\u7f06\u914d\u7f6e<\/th>\n                            <\/tr>\n                        <\/thead>\n                        <tbody>\n                            <tr>\n                                <td>Electric Rope Shovel<br>\u7535\u52a8\u7ef3\u94f2<\/td>\n                                <td>Class 5 Flexible<br>Class 5\u67d4\u6027<\/td>\n                                <td>50,000+ cycles<br>50,000+\u5faa\u73af<\/td>\n                                <td>Type 441 3\u00d795mm\u00b2 + 3E + P<br>Type 441 3\u00d795\u5e73\u65b9\u6beb\u7c73+3E+P<\/td>\n                            <\/tr>\n                            <tr>\n                                <td>Walking Dragline<br>\u6b65\u884c\u62d6\u94f2<\/td>\n                                <td>Class 5 Flexible<br>Class 5\u67d4\u6027<\/td>\n                                <td>30,000+ cycles<br>30,000+\u5faa\u73af<\/td>\n                                <td>Type 441 3\u00d7120mm\u00b2 + 3E + P<br>Type 441 3\u00d7120\u5e73\u65b9\u6beb\u7c73+3E+P<\/td>\n                            <\/tr>\n                            <tr>\n                                <td>Continuous Miner<br>\u8fde\u7eed\u91c7\u77ff\u673a<\/td>\n                                <td>Class 5 Flexible<br>Class 5\u67d4\u6027<\/td>\n                                <td>40,000+ cycles<br>40,000+\u5faa\u73af<\/td>\n                                <td>Type 441 3\u00d770mm\u00b2 + 3E + P<br>Type 441 3\u00d770\u5e73\u65b9\u6beb\u7c73+3E+P<\/td>\n                            <\/tr>\n                            <tr>\n                                <td>Mobile Crusher<br>\u79fb\u52a8\u7834\u788e\u673a<\/td>\n                                <td>Class 5 Flexible<br>Class 5\u67d4\u6027<\/td>\n                                <td>20,000+ cycles<br>20,000+\u5faa\u73af<\/td>\n                                <td>Type 441 3\u00d750mm\u00b2 + 3E + P<br>Type 441 3\u00d750\u5e73\u65b9\u6beb\u7c73+3E+P<\/td>\n                            <\/tr>\n                        <\/tbody>\n                    <\/table>\n                    <span class=\"table-caption\">Table 2: Type 441 cable applications requiring Class 5 flexible conductors \u88682\uff1a\u9700\u8981Class 5\u67d4\u6027\u5bfc\u4f53\u7684Type 441\u7535\u7f06\u5e94\u7528<\/span>\n                <\/div>\n\n                <p class=\"article-paragraph\">The electrical performance of Class 5 conductors also meets the current-carrying requirements for mining equipment power supply.

Type 441 cables specify flexible stranded tinned annealed copper conductors complying with AS\/NZS 1125, and since AS\/NZS 1125 is based on IEC 60228, Class 5 conductors meet the flexibility and electrical performance requirements for these demanding mining applications.
