Product Name: NOMEX Paper Wrapped Wire
Introduction: NOMEX paper wrapped wire is extruded or drawn from oxygen-free 
copper rod or eletrical round aluminum rod with certain specification mould and then 
wrapped with US Du Pont Company’s NOMEX paper of Type T410. It is widely applied in 
transformers, electric welding machines and other similar electricial instruments. The 
electrical bare copper or aluminum wire with extrusion process is the ideal material for 
NOMEX paper wrapped wire.
