Features

It is an enamelled strip with high mechanical, thermal and chemical properties.
Structurally, the insulation consists of a single layer of POLYAMIDE-IMIDE varnish.

Mechanically, its stand-out features are its excellent resistance to abrasion, high flexibility and adhesion to copper, meaning it is capable of withstanding the demanding deformations, stretching and crushing that occur even in the most modern manufacturing and winding processes in the industry. Thermally, the wire is capable of withstanding high working temperatures, occasional overloads and long thermal shock cycles. Chemically, the wire is compatible with most commercial impregnation resins and oils, coolants and cleaning fluids.

Despite being a complete wire, there may be applications that require a specific improvement, which is why we have a qualified technical team to study specific cases and prepare a project tailored to any need.
