Materials

Soft copper used for enameled rectangular wire shall conform to GB5584.2, the resistivity is not more than 0.01724Ω mm2/m at 20゜ According to different mechanical strength, below proof stress Rp0.2 is recommended：

C1 Rp0.2(>100~180)N/mm2

C1 Rp0.2(>181~220)N/mm2

C1 Rp0.2(>221~260)N/mm2

Soft aluminum used for enameled rectangular wire shall conform to GB5584. 3, the resistivity is not more than 0.0280Ω. mm/m at 20゜.

According to different electric insulation requirement to select Grade 1 enamel 0.08-0.11mm or Grade 2 enamel 0. 12-0.16mm. Generally epoxy resin increase of epoxy enameled rectangular wire is about 0. 03-0.05mm
