Engineering position: a flat cable is a motion component<\/h2><div class=\"note\"><b>PNCT-RF 4C \u00d7 185 mm\u00b2 is not simply a fixed PNCT cable drawn as a rectangle.<\/b> In a reel, festoon or moving transfer machine, every operating cycle changes the cable curvature, contact pressure and tensile distribution.

A fixed-installation class cannot be treated as a reeling qualification.<\/div><div class=\"box\"><b>Flat-cable duty<\/b><br>The major and minor dimensions, preferred plane, edge pressure and anti-torsion behaviour matter. A round-cable bending rule is not an acceptable substitute for the PNCT-RF drawing.<\/div><div class=\"box\"><b>Environmental duty<\/b><br>Rubber sheath selection must match oil, water, dust, UV, ozone, temperature, abrasion and possible chemical exposure.

In normal engineering notation this is read as PNCT-RF flat reeling cable \u2014 4C \u00d7 185 mm\u00b2 \u2014 0.6\/1 kV, subject to confirmation that 185SQ means 185 mm\u00b2 per core. This guide explains how to specify, install and qualify the cable without inventing the missing dynamic ratings. Public manufacturers describe PNCT-RF as a flat reeling\/festoon family; the exact Feichun construction must still be released against the machine duty.","protected":false},"author":1,"featured_media":25420,"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":[66,1,56],"tags":[9038,16,2446],"class_list":["post-25419","post","type-post","status-publish","format-standard","has-post-thumbnail","category-common-problems-encountered-in-cable-applications","category-uncategorized","category-reeling-cable","tag-medium-voltage-reeling-cable-6-10kv-specification","tag-din-vde-0250","tag-how-does-reeling-cable-differ-from-standard-power-cable","cs-entry"],"_links":{"self":[{"href":"https:\/\/feichuncables.com\/blog\/wp-json\/wp\/v2\/posts\/25419","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=25419"}],"version-history":[{"count":2,"href":"https:\/\/feichuncables.com\/blog\/wp-json\/wp\/v2\/posts\/25419\/revisions"}],"predecessor-version":[{"id":25426,"href":"https:\/\/feichuncables.com\/blog\/wp-json\/wp\/v2\/posts\/25419\/revisions\/25426"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/feichuncables.com\/blog\/wp-json\/wp\/v2\/media\/25420"}],"wp:attachment":[{"href":"https:\/\/feichuncables.com\/blog\/wp-json\/wp\/v2\/media?parent=25419"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/feichuncables.com\/blog\/wp-json\/wp\/v2\/categories?post=25419"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/feichuncables.com\/blog\/wp-json\/wp\/v2\/tags?post=25419"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
