Tinsel wire is a low-voltage, stranded wire in which each strand is a very thin copper ribbon spirally wrapped around a textile yarn, generally insulated with a textile braid, intended for use where severe flexing is expected.
Tinsel wire is a low-voltage, stranded wire built for extreme flexibility and resistance to flex fatigue. Instead of conventional round strands, each strand is a very thin copper ribbon spirally wrapped around a textile yarn core, and the insulation is generally a textile braid. This construction allows the wire to bend repeatedly without the metal fatigue that would break ordinary conductors, making it ideal where severe, repeated flexing is expected.
Because the thin copper ribbons flex around their textile cores rather than bending as solid wires, tinsel wire endures far more flex cycles than standard conductors. The trade-off is reduced current capacity, so tinsel wire is used for low-voltage signal applications rather than power.
In commercial and industrial settings, tinsel wire serves communication cords, retractable leads, and other applications subject to constant flexing. Recognizing the construction helps in understanding how wire is made to endure severe bending.

At Windy City Wire, an understanding of flexible conductor constructions, including tinsel wire, reflects a focus on matching cable to its application. Recognizing how copper ribbons on textile cores deliver extreme flex life helps illustrate the range of wire available for demanding flex applications.
