CU(Copper) Litz Wire Test Data From, Litz Wire, Cable - We are manufacturing extensive-variety of high frequency litz twine from thin sizes (extremely-nice zero.030mm x 1150 strands) to thick sizes (zero.100mm x 64,500 strands). Jacket, extrusion or serving (along with wrapping) : double kapton wrapped(cw, ccw), square kind, nylon(66), pure silk, nomex, teflon(fep, etfe, pfa), xlpe, xlpo, p.C, silicon, mylar, dacron wire and cable are available.
On the following desk, in case of copper twine, if the conductor’s diameter is 0.34mm, the tolerance of the diameter ought to be ±zero.006mm and the overall diameter ought to be zero.385mm(tolerance 0.1/2, -zero.004mm). On similar case, the max. Conductor resistance should be 322.6ω/km at 20℃. The others are same as 0.34mm.
The subsequent desk(anxiety table for coiling) suggests the coil tension based on gram as in line with the dimensions of copper conductor from 0.020mm~2.0mm. Therefore, you may count on the bending radius of the wound coil’s size and diverse winding condition of copper cord earlier than fabrication or production.
