Permeability of copper wire
WebJun 16, 2024 · As far as the copper conductors are concerned, THHN is identical to the Prestolite. Both are comprised of 19 strands of 29 AWG wire. The difference between the two products comes down to the insulation/jacketing: Prestolite uses CPE that is 57 mils thick. CPE has a dielectric constant of 5.5 THHN uses PVC that is 4 mils thick. WebMagnetic permeability ~1 – Diamagnetic. ASM Specialty Handbook: Copper and Copper Alloys (2001) Piezoresistivity. p 11 = 5.7 x 10^-3 Gpa ^-1. p 12 = 6.3 x 10^-3 Gpa^-1. C. Hu, …
