Silver-plated copper conductor three-layer insulating wire

The invention relates to a silver-plated copper conductor three-layer insulating wire, and the wire comprises a silver-plated copper conductor, two polyester insulating layers, and a polyamide resin insulating layer. The two polyester insulating layers sequentially extrude the exterior of the silver-plated copper conductor. The polyamide resin insulating layer extrudes the exteriors of the two polyester insulating layers. Compared with the prior art, the wire is good in conductivity, is stable in current, and is small in line diameter. 本发明涉及种镀银铜导体三层绝缘线，包括根镀银铜导体、两层聚酯绝缘层以及聚酰胺树脂绝缘层，所述的两层聚酯绝缘层依次挤包于单根镀银铜导体之外，所述的聚酰胺树脂绝缘层挤包于两层聚酯绝缘层之外。与现有技术相比，本发明具有导电性好、电流稳定、线径小等优点。
