Quarterly comprehensive testing including insulation resistance, earth continuity, and visual inspection is recommended for most mining applications. Annual testing with complete electrical and mechanical evaluation provides baseline condition assessment and trend analysis for predictive maintenance. Any cable that has undergone repair must be tested immediately after the repair and before being returned to service. <span class=\"chinese-text\">\u673a\u5668\u64cd\u4f5c\u5458\u5e94\u6bcf\u5929\u6216\u6bcf\u73ed\u6b21\u524d\u8fdb\u884c\u76ee\u89c6\u68c0\u67e5\uff0c\u68c0\u67e5\u662f\u5426\u6709\u53ef\u89c1\u635f\u574f\u3001\u62a4\u5957\u5272\u4f24\u3001\u88f8\u9732\u5bfc\u4f53\u6216\u5f02\u5e38\u7535\u7f06\u53d1\u70ed\u3002<\/span><\/p>\n\n            <h3>Retirement Criteria <span class=\"chinese-text\">\u62a5\u5e9f\u6807\u51c6<\/span><\/h3>\n            <p>Cables should be withdrawn from service when insulation resistance falls below 1 M\u03a9 and cannot be restored through cleaning or drying, when the cable has undergone multiple repairs in the same section indicating chronic failure, when the jacket shows extensive deterioration with multiple punctures or cuts, when conductor corrosion is evident despite the tinned copper construction, or when the cable fails to meet flexibility requirements due to age-hardening of the EPR insulation. The decision to retire a cable should consider the total cost of ownership, including frequent repair costs, downtime, and safety risks. <span class=\"chinese-text\">\u5f53\u7edd\u7f18\u7535\u963b\u4f4e\u4e8e1 M\u03a9\u4e14\u65e0\u6cd5\u901a\u8fc7\u6e05\u6d01\u6216\u5e72\u71e5\u6062\u590d\u65f6\uff0c\u7535\u7f06\u5e94\u505c\u6b62\u4f7f\u7528\u3002<\/span><\/p>\n        <\/section>\n\n        <section class=\"references-section\">\n            <h2>Authoritative References and Standards <span class=\"chinese-text\">\u6743\u5a01\u53c2\u8003\u8d44\u6599\u548c\u6807\u51c6<\/span><\/h2>\n            \n            <div class=\"reference-item\">\n                <strong>AS\/NZS 1747:2022 &#8211;
