JIS C 3327 designation system is elegant in its logic. Every cable name follows a predictable, parseable structure 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 15 cable types defined by the standard—and immediately know what the cable is made of, how flexible it is, and what applications it is suited for.

JIS C 3327 Cable Code Designation

JIS C 3327 designation system is elegant in its logic. Every cable name follows a predictable, parseable structure 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 15 cable types defined by the standard—and immediately know what the cable is made of, how flexible it is, and what applications it is suited for.

6600V 3PNCT cable, manufactured to the Japanese Industrial Standard JIS C 4353 Class 3, is the purpose-built high voltage cable solution for these demanding applications. It combines the same fundamental material technologies proven in the 600V 2PNCT family—EP rubber insulation, polychloroprene rubber sheathing, tinned copper conductors, tinned copper/cotton yarn braid shielding, and Kevlar® para-aramid fibre braided tensile reinforcement—but with substantially enhanced insulation systems and construction techniques required for safe, reliable operation at 6,600V. The cable features a semiconductive stress-grading layer at the conductor/insulation interface, 5.0–5.5 mm thick EP rubber insulation (compared to 0.8–2.5 mm in 600V cables), a metallic braid shield for electric field containment, and a dual-layer polychloroprene sheath with an intermediate reinforcement layer for maximum mechanical protection.
