Stranded enameled wire is a multi-strand enameled wire that is twisted by a machine, and its voltage needs to be confirmed according to the number of strands. The more the number of strands, the lower the voltage standard, and the details are multiplied by the standard of the enameled wire. Refer to (JISC3202-1994 ).
When the number of strands (N) < 20, the breakdown of the stranded wire is V = breakdown voltage of a single enameled wire * 90%.
When the number of strands is 20≤N<60, the breakdown voltage of the stranded wire is V=the breakdown voltage of a single enameled wire*80%.
When the number of strands is 60≤N<120, the breakdown voltage of the stranded wire is V=the breakdown voltage of a single enameled wire*70%.
When the number of strands is N≥120, the breakdown voltage of the stranded wire is V=the breakdown voltage of a single enameled wire*60%.


Stranding direction refers to the direction of wire take-up in the production process, generally divided into forward (S) that is clockwise, reverse (Z) is counterclockwise
Twisting distance The ratio of the effective measurement distance to the number of turns of the turning will be set by calculation, which is the twisting distance (pitch) of the stranded wire, 4-110mm
Color Natural/Red

Reel Specifications PT-4/PT-10/PT-15
Application standard Refer to IEC JIS GB standard for enameled wire
Features Compared with single conductors, under the same conductor cross-sectional area, the surface area of the stranded wire is greatly increased, effectively suppressing the influence of the skin effect, and significantly improving the inductance Q value.
Application High frequency transformers and inductors, communication equipment, ultrasonic equipment, video equipment, radio equipment, induction heating equipment, etc.
Product Certification ISO9001/ISO14001 /RoHS/SGS
Precautions The finished stranded wire is allowed to have 3 single enameled wire connectors per axis
