Product Introduction

Enameled rectangular wire is a type of winding wire made by oxygen-free copper rod or electric round aluminum rod which drawn or extruded by dies with special size, then over coated with enamel repetitiously. Mainly be used in winding of transformer、electromotor、generator and various electric devices.

Manufacturing Scope

Conductor thickness a: 0.90-5.00mm
Conductor width b: 3.00-16.00mm
Suggested width/thickness: 1.5<b/a<7.5

Materials

The resistivity of soft copper 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
C2 Rp0.2(>180~220)N/ mm2
C3 Rp0.2(>220~260)N/ mm2
The resistivity of rectangular aluminum 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.
