enameled copper clad aluminum wire winding wire cca
1.Application
Copper Clad Aluminum wire (CCA wire) is an electrical conductor which has an outer sleeve of copper metallurgically bonded to a solid aluminum core. The combination of these two metals make it uniquely suited to many electrical applications.
In high frequency signal transmission field, it is applied to:
• Standard Material of Conductor in CATV Coaxial Cable; 50 Ohm Radio Frequency Aerial; Leaky Cable; Soft Coaxial Radio Frequency Cable; Data Cable
In power transmission field, it can be applied to:
• Stranded wire; Power Cable; Control Cable; Automotive cable; Building distribution wire; Busbar; Radio Frequency shielding;
In special electromagnetic wire, it can be applied to:
• Coils in motor and fans, mahjong machine, Loudspeakers, Voice coils (e.g. in Headphone, Headset, ...)
Manufacture Scope: 0.12MM~5.50MM
2.Features
Compared to copper conductors:
Higher Flexibility due to lower elastic modulus
63% material weight reduction due to lower specific gravity of CCA over regular copper
Compared to aluminum conductors:
Better corrosion resistance than aluminum due to copper layer
Lower resistance due to high electric conductivity of copper
Better Solder ability
Higher strength than aluminum
