Spools and Packaging for Enamelled Wire

General

Enamelled copper wire [magnet wire] is wound on spools of different sizes and shapes. The wire diameter determines the spool size which can be used. Ultrafine wire typically is produced on smaller spools while heavy wire is wound on very large spools.

Different global standards specify different spool types which are typically associated with each continents standard.

Selection of Spool Type:
Spool Types Wire Sizes Characteristics
Biconical 0.010 - 0.15 mm Biconical spool for fine and ultrafine wire, superb de-reeling capability, ideal for high speed winding machines
Cylindrical 0.05 - 0.50 mm Straight barrel spool, solid traditional design
Tapered 0.10 - 0.50 mm Stable winding due to tapered barrel spool for heavier sizes
Container Container for large spools
