If two standard cables cross each other and vibrate (as they do on a train), the insulation can wear down, causing a phase-to-phase short circuit.\n            <br><strong>The NSHXAF\u00d6 Solution:<\/strong> By using a cable rated for <strong>3000V (3kV)<\/strong> in a <strong>1000V<\/strong> system, the insulation wall thickness is significantly increased. This physical barrier is so robust that it is considered mechanically impossible for a short circuit to occur between cables under normal operating conditions. It renders the installation &#8220;inherently short-circuit proof&#8221; and &#8220;earth-fault proof.&#8221;<\/p>\n            <p class=\"cn-content\"><strong>\u9884\u9632\u7684\u7269\u7406\u539f\u7406\uff1a<\/strong> \u989d\u5b9a\u7535\u538b\u4e3a 1kV \u7684\u6807\u51c6\u7535\u7f06\u7edd\u7f18\u5c42\u76f8\u5bf9\u8f83\u8584\u3002\u5982\u679c\u4e24\u6839\u6807\u51c6\u7535\u7f06\u76f8\u4e92\u4ea4\u53c9\u5e76\u632f\u52a8\uff08\u5982\u5728\u706b\u8f66\u4e0a\uff09\uff0c\u7edd\u7f18\u5c42\u53ef\u80fd\u4f1a\u78e8\u635f\uff0c\u5bfc\u81f4\u76f8\u95f4\u77ed\u8def\u3002<br><strong>NSHXAF\u00d6 \u89e3\u51b3\u65b9\u6848\uff1a<\/strong> \u901a\u8fc7\u5728 <strong>1000V<\/strong> \u7cfb\u7edf\u4e2d\u4f7f\u7528\u989d\u5b9a\u7535\u538b\u4e3a <strong>3000V (3kV)<\/strong> \u7684\u7535\u7f06\uff0c\u7edd\u7f18\u58c1\u539a\u663e\u8457\u589e\u52a0\u3002\u8fd9\u79cd\u7269\u7406\u5c4f\u969c\u975e\u5e38\u575a\u56fa\uff0c\u88ab\u8ba4\u4e3a\u5728\u6b63\u5e38\u64cd\u4f5c\u6761\u4ef6\u4e0b\u7535\u7f06\u4e4b\u95f4\u53d1\u751f\u77ed\u8def\u5728\u673a\u68b0\u4e0a\u662f\u4e0d\u53ef\u80fd\u7684\u3002\u8fd9\u4f7f\u5f97\u5b89\u88c5\u5177\u6709\u201c\u672c\u8d28\u77ed\u8def\u4fdd\u62a4\u201d\u548c\u201c\u63a5\u5730\u6545\u969c\u4fdd\u62a4\u201d\u7279\u6027\u3002<\/p>\n        <\/div>\n\n        <table class=\"spec-table\">\n            <thead>\n                <tr>\n                    <th>Application Scenario (\u5e94\u7528\u573a\u666f)<\/th>\n                    <th>Why NSHXAF\u00d6 is Mandatory (\u4e3a\u4ec0\u4e48\u5fc5\u987b\u4f7f\u7528)<\/th>\n                <\/tr>\n            <\/thead>\n            <tbody>\n                <tr>\n                    <td><strong>Before the Main Fuse<\/strong><br>(\u4e3b\u7194\u65ad\u5668\u4e4b\u524d)<\/td>\n                    <td>Connections from the battery or pantograph to the main breaker have <strong>NO protection<\/strong>.

It is unique in the electrical industry because, although it is rated for 1.8\/3 kV (or even 3.6\/6 kV), it is primarily used in 1000V (1kV) Low Voltage circuits. This &#8220;over-engineering&#8221; of the insulation thickness allows it to be classified as &#8220;inherently short-circuit proof&#8221; (kurzschlusssicher) when installed in switchgear and railway vehicles. It acts as a fail-safe against catastrophic electrical faults where fusing protection is physically impossible or delayed.\nNSHXAF\u00d6 \u662f\u4e00\u79cd\u6839\u636e DIN VDE 0250 \u7b2c 606 \u90e8\u5206 \u5236\u9020\u7684\u4e13\u7528\u65e0\u5364\u5355\u82af\u6a61\u80f6\u7535\u7f06\u3002\u5b83\u5728\u7535\u6c14\u884c\u4e1a\u4e2d\u72ec\u4e00\u65e0\u4e8c\uff0c\u5c3d\u7ba1\u5176\u989d\u5b9a\u7535\u538b\u4e3a 1.8\/3 kV\uff08\u751a\u81f3 3.6\/6 kV\uff09\uff0c\u4f46\u4e3b\u8981\u7528\u4e8e 1000V (1kV) \u4f4e\u538b\u7535\u8def\u3002\u8fd9\u79cd\u7edd\u7f18\u539a\u5ea6\u7684\u201c\u8fc7\u5ea6\u8bbe\u8ba1\u201d\u4f7f\u5176\u5728\u5b89\u88c5\u4e8e\u5f00\u5173\u8bbe\u5907\u548c\u94c1\u8def\u8f66\u8f86\u4e2d\u65f6\uff0c\u88ab\u5f52\u7c7b\u4e3a\u201c\u672c\u8d28\u77ed\u8def\u4fdd\u62a4\u201d\uff08kurzschlusssicher\uff09\u3002\u5b83\u5145\u5f53\u4e86\u9632\u6b62\u707e\u96be\u6027\u7535\u6c14\u6545\u969c\u7684\u6545\u969c\u5b89\u5168\u88c5\u7f6e\uff0c\u9002\u7528\u4e8e\u7269\u7406\u4e0a\u65e0\u6cd5\u5b89\u88c5\u7194\u65ad\u4fdd\u62a4\u6216\u4fdd\u62a4\u5ef6\u8fdf\u7684\u573a\u5408\u3002","protected":false},"author":1,"featured_media":4874,"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":[66,464,56],"tags":[32457,32472,32467,32486,779,32476,2484,32469,32460,32464,32479,25077,32465,32478,32459,32455,32462,32471,32458,23949,32463,32461,12937,32466,32456,32470,32468,32474,32481,32485,32161,32480,32483,32488,32487,32477,32473,32475,32484,32482],"class_list":["post-4873","post","type-post","status-publish","format-standard","has-post-thumbnail","category-common-problems-encountered-in-cable-applications","category-flexible-cables-with-high-bending-life-and-fatigue-resistance","category-reeling-cable","tag-1-8-3kv-rubber-cable","tag-1-8-3kv","tag-3-6-6kv-short-circuit-proof","tag-3-6-6kv","tag-3gi3-epr-insulation","tag-3gi3","tag-anhui-feichun-special-cable","tag-bogie-wiring-protection","tag-din-vde-0100-520-installation","tag-en-45545-2-railway-fire-safety","tag-en-45545-2","tag-halogen-free-railway-cable","tag-hm3-polymer-sheath","tag-hm3","tag-inherently-earth-fault-proof-cable","tag-nshxafo-cable-specifications","tag-nshxafo-vs-nsgafou","tag-nshxafo","tag-omnibuses-power-cable","tag-rolling-stock-wiring","tag-short-circuit-proof-single-core","tag-switchgear-internal-wiring","tag-tinned-copper-class-5-conductor","tag-tramway-electrical-systems","tag-vde-0250-606-standard","tag-vde-0250-606","tag-zero-halogen-rubber-cable","tag-32474","tag-32481","tag-32485","tag-32161","tag-32480","tag-vde","tag-32488","tag-32487","tag-32477","tag-32473","tag-32475","tag-32484","tag-32482","cs-entry"],"_links":{"self":[{"href":"https:\/\/feichuncables.com\/blog\/wp-json\/wp\/v2\/posts\/4873","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=4873"}],"version-history":[{"count":1,"href":"https:\/\/feichuncables.com\/blog\/wp-json\/wp\/v2\/posts\/4873\/revisions"}],"predecessor-version":[{"id":4875,"href":"https:\/\/feichuncables.com\/blog\/wp-json\/wp\/v2\/posts\/4873\/revisions\/4875"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/feichuncables.com\/blog\/wp-json\/wp\/v2\/media\/4874"}],"wp:attachment":[{"href":"https:\/\/feichuncables.com\/blog\/wp-json\/wp\/v2\/media?parent=4873"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/feichuncables.com\/blog\/wp-json\/wp\/v2\/categories?post=4873"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/feichuncables.com\/blog\/wp-json\/wp\/v2\/tags?post=4873"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
