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.

What is JIS C 3327 Cable?

JIS C 3327 represents the Japanese Industrial Standard governing the design, construction, and performance requirements for 600-volt rubber insulated flexible cables. This comprehensive standard, officially designated as “600 V Rubber Insulated Flexible Cables,” establishes rigorous specifications ensuring these cables deliver reliable electrical performance, mechanical durability, and environmental resistance across demanding industrial applications. The standard encompasses multiple cable classifications distinguished by conductor flexibility classes, insulation materials, and sheath compositions, each optimized for specific operational requirements.
