What governing standard and construction define POLYIMIDE-FEP FLAT WIRE (Class 240 Polyimide-FEP Film-Tape Wrapped Rectangular Copper Winding Wire)?

POLYIMIDE-FEP FLAT WIRE (Class 240 Polyimide-FEP Film-Tape Wrapped Rectangular Copper Winding Wire) is manufactured in accordance with IEC 60317-43 / NEMA MW 61-C for Up to 6 kV service over -60 °C to +240 °C. Its 2-layer construction comprises stranded copper conductor, polyimide-fep composite tape.

What is the minimum bending radius and installation temperature for POLYIMIDE-FEP FLAT WIRE?

The minimum installed bending radius for POLYIMIDE-FEP FLAT WIRE is 6 × OD across its continuous operating temperature range of -60 °C to +240 °C, ensuring mechanical and dielectric stability without conductor or insulation strain.

How are the concentric layers of POLYIMIDE-FEP FLAT WIRE arranged from inside to outside?

From inside to outside, the construction sequence is: (01) Stranded copper conductor (High-conductivity copper conductor per IEC 60317-43 / NEMA MW 61-C); (02) Polyimide-FEP composite tape (Polyimide-FEP composite tape (lapped tape)).

What factory test certificates are supplied with POLYIMIDE-FEP FLAT WIRE?

Every production drum or spool of POLYIMIDE-FEP FLAT WIRE undergoes routine conductor DC resistance, dimensional and dielectric/integrity testing per IEC 60317-43 / NEMA MW 61-C, and is delivered with an EN 10204 3.1 factory test certificate.
