Enameled Rectangular Wire

Enameled Rectangular Wire
Product Detailed
a type of winding wire made by copper or aluminum rod over coated with enamel repetitiously used in winding of transformer

Product typesClass 180 polyesterimide enameled rectangular copper (aluminum) wire Class 200 polyesterimid over-coated with polyamide-imide enameled rectangular copper (alumnium) wire Class 120(155) polyvinyl acetal enameled rectangular copper (aluminum) wire Class 120 polyvinyl acetal enameled with bondable epoxy res inrectangular copper (alumnium) wire If required other types enameled wire, please contact with us.

Manufacturing scopeConductor thickness a: 0.90-5.00mmConductor width b: 3.00-16.00mmSuggested width/thickness: 1.5<b/a<7.5If required size out of above scope, please contact with us.

MaterialsSoft copper used for enameled rectangular wire shall conform to GB5584.2-85, the resistivity is not more than 0.01724Ω·mm2/m at 20°. According to different mechanical strength, below proof stressRp0.2 is recommended:C1 Rp0.2(>100~180)N/ mm2C2 Rp0.2(>180~220)N/ mm2C3 Rp0.2(>220~260)N/ mm2Soft aluminum used for enameled rectangular wire shall conform to GB5584.3-85, the resistivity is not more than 0.0280Ω·mm2/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.Our company adopts medium wearing instrument(tgδ) to filter enameling technics, makes enamel solidify more perfect. If special enamel thickness required or use other types enameled wire, please contact with us.
