This distinction is fundamental to understanding whether a cable is manufactured to German national standards or European harmonised standards. \u5728\u56fd\u9645\u7535\u7f06\u884c\u4e1a\u4e2d\uff0c\u7535\u7f06\u578b\u53f7\u5f00\u5934\u7684\u5b57\u6bcd&#8221;N&#8221;\u5177\u6709\u91cd\u8981\u7684\u6280\u672f\u548c\u6cd5\u89c4\u542b\u4e49\u3002\u7136\u800c\uff0c\u8bb8\u591a\u5de5\u7a0b\u5e08\u5728\u6bd4\u8f83\u6807\u6709N\uff08\u4e0d\u5e26\u62ec\u53f7\uff09\u548c(N)\uff08\u5e26\u62ec\u53f7\uff09\u7684\u7535\u7f06\u65f6\u4f1a\u611f\u5230\u56f0\u60d1\u3002\u8fd9\u79cd\u533a\u522b\u5bf9\u4e8e\u7406\u89e3\u7535\u7f06\u662f\u6309\u7167\u5fb7\u56fd\u56fd\u5bb6\u6807\u51c6\u8fd8\u662f\u6b27\u6d32\u534f\u8c03\u6807\u51c6\u5236\u9020\u7684\u81f3\u5173\u91cd\u8981\u3002","protected":false},"author":1,"featured_media":4817,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"csco_singular_sidebar":"left","csco_page_header_type":"title","csco_page_load_nextpost":"","footnotes":""},"categories":[94,56],"tags":[31944,754,20697,47,40,31947,31942,31952,31958,31951,21891,18897,998,16,31945,18617,1238,2587,31950,18806,420,419,655,172,1080,1092,3126,111,2460,31943,18910,31949,20083,31959,10934,2598,10496,18905,18861,31946,18906,31948,18904,796,1138,2531,17,994,27869,20049,31954,769,27098,22788,31956,11983,31957,31955,31953,11984,22977],"class_list":["post-4816","post","type-post","status-publish","format-standard","has-post-thumbnail","category-din-vde-0250-mining-cable","category-reeling-cable","tag-n-cable-code","tag-nshtou","tag-ntmcgewou","tag-ntscgewoeu","tag-ntscgewou","tag-nyy-cable-2","tag-cable-designation","tag-cable-designation-decoder","tag-cable-designation-system","tag-cable-type-code","tag-cenelec","tag-cenelec-cable-standard","tag-crane-cable","tag-din-vde-0250","tag-din-vde-0292","tag-european-cable-standard","tag-excavator-cable","tag-flexible-cable","tag-german-cable-nomenclature","tag-german-industrial-cable","tag-har-cable","tag-harmonised-cable","tag-hd-603","tag-hd-620","tag-heavy-duty-cable","tag-material-handling-cable","tag-medium-voltage-flexible-cable","tag-mining-cable","tag-mv-reeling-cable","tag-n-bracket-meaning","tag-n2xy-cable","tag-normenleitung","tag-nsgafou-cable","tag-nshtou-3","tag-nshxafo-cable-2","tag-nsshou-cable","tag-ntscgewou-3","tag-nycwy-cable","tag-nyy-cable","tag-nyy-j","tag-nyy-j-cable","tag-nyy-o","tag-nyy-o-cable","tag-oil-resistant-cable","tag-outdoor-cable","tag-port-crane-cable","tag-reeling-cable","tag-trailing-cable","tag-vde-cable-standard","tag-vde-certification","tag-vde","tag-weather-resistant-cable","tag-27098","tag-22788","tag-31956","tag-11983","tag-31957","tag-31955","tag-31953","tag-11984","tag-22977","cs-entry"],"_links":{"self":[{"href":"https:\/\/feichuncables.com\/blog\/wp-json\/wp\/v2\/posts\/4816","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/feichuncables.com\/blog\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/feichuncables.com\/blog\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/feichuncables.com\/blog\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/feichuncables.com\/blog\/wp-json\/wp\/v2\/comments?post=4816"}],"version-history":[{"count":2,"href":"https:\/\/feichuncables.com\/blog\/wp-json\/wp\/v2\/posts\/4816\/revisions"}],"predecessor-version":[{"id":4819,"href":"https:\/\/feichuncables.com\/blog\/wp-json\/wp\/v2\/posts\/4816\/revisions\/4819"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/feichuncables.com\/blog\/wp-json\/wp\/v2\/media\/4817"}],"wp:attachment":[{"href":"https:\/\/feichuncables.com\/blog\/wp-json\/wp\/v2\/media?parent=4816"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/feichuncables.com\/blog\/wp-json\/wp\/v2\/categories?post=4816"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/feichuncables.com\/blog\/wp-json\/wp\/v2\/tags?post=4816"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
