  • Product description

Insulated wire is an insulation material that adds one or more layers of insulation on the surface of a conductor through extrusion or winding processes, and obtains safety specification certification. Mainly used in transformers and inductors, using three-layer insulated wires with reinforced insulation, there is no need for additional insulation tape and isolation tape between the primary and secondary winding of transformers, thereby achieving product miniaturization and reducing costs.


The insulation wire category of Weihan Electric Wire is complete, with mature technology, and has successfully replaced foreign brands in many application fields.
