id=\"s1\">\n <h2>Introduction: Why Cable Code Designation Matters<\/h2>\n\n <p>Every cable manufactured to the Japanese Industrial Standard <strong>JIS C 3327<\/strong> carries a code designation that functions as a compressed technical specification. When a crane manufacturer specifies a <code class=\"cd\">2PNCT<\/code> cable, or a port terminal engineer orders a <code class=\"cd\">3PNCT<\/code> replacement, the code itself communicates the cable’s flexibility class, insulation material, sheath material, and cable category\u2014without requiring the engineer to look up a product catalogue. For anyone working with Japanese-standard cables\u2014whether in port crane installations, ship unloader systems, industrial material handling, or general-purpose flexible power distribution\u2014understanding this code system is a fundamental professional skill.<\/p>\n\n <p>The JIS C 3327 designation system is elegant in its logic. Every cable name follows a <strong>predictable, parseable structure<\/strong> where each character or character group carries a specific, unambiguous meaning. Once you understand the five material symbols and the four flexibility classes, you can decode any of the <strong>15 cable types<\/strong> defined by the standard\u2014and immediately know what the cable is made of, how flexible it is, and what applications it is suited for.<\/p>\n\n <p>This reference guide provides the complete decoding system for JIS C 3327 cable codes, with worked examples, a visual symbol dictionary, and a cross-reference to Feichun’s product range. Bookmark this page\u2014it will save you time on every Japanese-standard cable specification you encounter.<\/p>\n <\/section>\n\n \n <section class=\"body\" id=\"s2\">\n <h2>The Four-Part Code Structure<\/h2>\n\n <p>Every JIS C 3327 cable code follows the same structural formula. The code is assembled from up to four parts, read left to right:<\/p>\n\n <div class=\"decode\">\n <div class=\"seg cls\"><span class=\"val\">Class<\/span><span class=\"lbl\">Flexibility<\/span><\/div>\n <span class=\"plus\">+<\/span>\n <div class=\"seg ins\"><span class=\"val\">Insulation<\/span><span class=\"lbl\">Material Code<\/span><\/div>\n <span class=\"plus\">+<\/span>\n <div class=\"seg sht\"><span class=\"val\">Sheath<\/span><span class=\"lbl\">Material Code<\/span><\/div>\n <span class=\"plus\">+<\/span>\n <div class=\"seg base\"><span class=\"val\">CT<\/span><span class=\"lbl\">Flexible Cable<\/span><\/div>\n <\/div>\n\n <p><strong>Part 1 \u2014 Class Number (1, 2, 3, or 4):<\/strong> A single digit at the beginning of the code that defines the cable’s flexibility classification. Class 1 is the least flexible; Class 4 is the most flexible. The class number is omitted only for the special case of silicone rubber cables (KKCT), which have a single class designation.<\/p>\n\n <p><strong>Part 2 \u2014 Insulation Material Code (optional letter):<\/strong> A single letter identifying the insulation material. If this letter is absent, the insulation is natural rubber (the default material in the original JIS standard). If present, it identifies a non-default insulation material: <strong>P<\/strong> for EP rubber, <strong>K<\/strong> for silicone rubber, etc.<\/p>\n\n <p><strong>Part 3 \u2014 Sheath Material Code (optional letter):<\/strong> A single letter identifying the outer sheath material. If absent, the sheath is natural rubber (default). If present, it identifies a non-default sheath material: <strong>R<\/strong> for chloroprene rubber (polychloroprene), <strong>H<\/strong> for polyethylene chlorosulfonide rubber, <strong>K<\/strong> for silicone rubber, etc.<\/p>\n\n <p><strong>Part 4 \u2014 CT (always present):<\/strong> The suffix <strong>CT<\/strong> appears at the end of every code. It stands for <em>Cabtyre<\/em>\u2014the Japanese industrial term for a flexible cable designed for portable or dynamic applications. The CT suffix is the universal identifier that marks a cable as a JIS C 3327 flexible cable rather than a fixed-installation cable covered by other standards.<\/p>\n\n <div class=\"note blue\">\n <div class=\"nt\">The “Implicit Default” Rule<\/div>\n <p>The JIS C 3327 code system uses <strong>natural rubber as the implicit default<\/strong> for both insulation and sheath. When a material code letter is <em>absent<\/em>, natural rubber is implied. This is why the simplest cable designation is just <code class=\"cd\">CT<\/code> (with a class number prefix)\u2014it means natural rubber insulation + natural rubber sheath + flexible cable. Material code letters only appear when the cable uses a <em>non-default<\/em> material. Understanding this “absence means natural rubber” rule is the key to decoding any JIS C 3327 cable name.<\/p>\n <\/div>\n\n <\/section>\n\n \n <section class=\"body\" id=\"s3\">\n <h2>Symbol Dictionary: Every Letter Decoded<\/h2>\n\n <p>JIS C 3327 uses exactly <strong>six symbols<\/strong> to encode all cable information.

In codes like <code class=\"cd\">RNCT<\/code>, the <code class=\"cd\">N<\/code> appears explicitly to indicate natural rubber insulation (because the sheath letter <code class=\"cd\">R<\/code> is already present and the code needs to show both materials). In codes like <code class=\"cd\">CT<\/code>, natural rubber is implied for <em>both<\/em> insulation and sheath\u2014no letters are needed because both materials are the default. This dual behaviour of the <code class=\"cd\">N<\/code> symbol is the most common source of confusion when first learning the JIS coding system.<\/p>\n <\/div>\n\n <\/section>\n\n \n <section class=\"body\" id=\"s4\">\n <h2>Flexibility Classes: 1 Through 4<\/h2>\n\n <p>The class number prefix defines the cable’s <strong>conductor flexibility<\/strong> per IEC 60228 and JIS C 3327. Higher class numbers indicate finer conductor stranding and greater flexibility:<\/p>\n\n <div class=\"tw\">\n <table>\n <caption>JIS C 3327 Flexibility Classes<\/caption>\n <thead><tr><th>Class<\/th><th>Flexibility Level<\/th><th>Conductor Construction<\/th><th>Typical Applications<\/th><\/tr><\/thead>\n <tbody>\n <tr><td><strong>Class 1<\/strong><\/td><td>Rigid \/ Solid<\/td><td>Solid conductor or coarse stranding.

Silicone rubber cables have inherently high flexibility due to the material’s extremely low elastic modulus, and the standard defines a single flexibility specification for KKCT cables rather than offering multiple classes. If you encounter a JIS cable code with no leading number, it is a silicone rubber cable.<\/p>\n <\/div>\n\n <\/section>\n\n \n <section class=\"body\" id=\"s5\">\n <h2>Insulation Materials: The First Variable<\/h2>\n\n <p>The insulation material is the dielectric layer that separates the conductor from the cable’s metallic screen or sheath, providing electrical isolation at the rated voltage.
