Storing Enamelled Aluminum Wire

To ensure the quality and prolong the lifespan of enamelled aluminum wire, proper storage methods are crucial. Below are the best practices for storing enamelled aluminum wire:

Storage Points	Description
Maintain a Dry Environment	Enamelled aluminum wire is sensitive to moisture. High humidity can lead to corrosion of the wire and damage to the insulation layer. It should be stored in a dry, low-humidity environment.

Avoid Direct Sunlight	Avoid exposing the wire to direct sunlight or ultraviolet radiation to prevent damage to the insulation coating. It should be stored in a shaded area.
Proper Winding and Tension	Ensure the wire on the spool is wound with even tension. Avoid excessive or insufficient tension, as it may lead to wire bending, tangling, or coating damage.
Clean Environment	The storage environment should be clean and dust-free to prevent dirt or dust particles from contaminating the insulation layer, which could affect electrical conductivity.
Avoid Mechanical Damage	Keep the wire away from sharp objects or heavy items to prevent scratches or damage to the insulation coating. Handle with care during transportation.
Store Spools Vertically	Spools should be stored vertically to prevent the wire from shifting or tangling, maintaining storage order and wire integrity.
Sealed Protection	If possible, store spools in sealed plastic bags or containers to further prevent moisture and contamination.
