What governing standard and construction define MULTIFILAR BONDED MAGNET WIRE (Parallel Multifilar Self-Bonding Polyurethane Enamelled Copper Winding Wire)?

MULTIFILAR BONDED MAGNET WIRE (Parallel Multifilar Self-Bonding Polyurethane Enamelled Copper Winding Wire) is manufactured in accordance with IEC 60317-20 / IEC 60317-35 for Up to 1000 V service over -40 °C to +155 °C. Its 3-layer construction comprises stranded copper conductor, polyurethane 155 enamel, polyvinyl-butyral bond coat.

What is the minimum bending radius and installation temperature for MULTIFILAR BONDED MAGNET WIRE?

The minimum installed bending radius for MULTIFILAR BONDED MAGNET WIRE is 5 × OD across its continuous operating temperature range of -40 °C to +155 °C, ensuring mechanical and dielectric stability without conductor or insulation strain.

How are the concentric layers of MULTIFILAR BONDED MAGNET WIRE arranged from inside to outside?

From inside to outside, the construction sequence is: (01) Stranded copper conductor (High-conductivity copper conductor per IEC 60317-20 / IEC 60317-35); (02) Polyurethane 155 enamel (Polyurethane 155 enamel (individual core / group layer)); (03) Polyvinyl-butyral bond coat (Extruded Polyvinyl-butyral bond coat protective layer (individual core / group layer)).

What factory test certificates are supplied with MULTIFILAR BONDED MAGNET WIRE?

Every production drum or spool of MULTIFILAR BONDED MAGNET WIRE undergoes routine conductor DC resistance, dimensional and dielectric/integrity testing per IEC 60317-20 / IEC 60317-35, and is delivered with an EN 10204 3.1 factory test certificate.
