New Product Conductor Copper Clad Aluminum Alloy Wire
Copper Clad Aluminum wire (CCA wire)is an electrical conductor which has an outer sleeve of copper metallurgically bonded to a solid aluminum alloy core. The combination of these two metals makeit uniquely suited to many electrical applications
Standard of copper clad aluminum wire :
SJ/T 11223-2000
ASTM B 566-93
Feature:
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 Solderability
Higher strength than aluminum
Application:
In high frequency signal transmission field, it is applied to:
l Standard Material of Conductor in CATV Coaxial Cable;
l 50 Ohm Radio Frequency Aerial;
l Leaky Cable;
l Soft Coaxial Radio Frequency Cable;
l Data Cable
In power transmission field, it can be applied to:
l Stranded wire;
l Power Cable;
l Control Cable;
l automotive cable;
l Building distribution wire;
l Busbar;
l Radio Frequency shielding;
In special electromagnetic wire, it can be applied to:
l Coils in motor and fans, mahjong machine, Loudspeakers
l Voice coils (e.g. in Headphone, Headset, ...)
l Windings
