Product Overview

Description

factory price copper clad aluminum busbar CCA busbar 

 

 

Copper Clad Aluminum busbar (CCA busbar) is a kind of busbar with flatted cross section and produced by applying unique manufacture technology for bimetallic composite material, by means of multiple plastic deformation and heat treatment process. 

 

Status: Annealed and Hard drawn

Manufacturing Range(Thickness*Width):

2MM*2MM-18MM*200MM(Length is based on customer’s requirement)

 

 

 

CCA busbar physical characteristics:

Copper and Aluminum volume ratio	15:85	20:80
Copper weight ratio	37:63	45:55

Linear expansion coefficient	2.25*10-5℃

Characteristics comparison between CCA busbar and Copper bubar

	Resistivity (ohm.mm2/m)	Conductivity (% I.A.C.S)	Tensile strength (Mpa)	Density (g/cm3)	Copper volume (%)	Current Carrying Capacity
CCA busbar	≤0.02455	≥66.2	≤138	3.75+/-0.07	17%+/-2%	85%+/-3%
Copper busbar	0.017241	100	≥250	8.89	100%	100%

 

How to choose Copper Clad Aluminum Busbar:

Normally, In order to keep same current carrying capacity, when replacing copper busbar, cross section area of CCA busbar should be enlarge 15%~20%.

Application:

Wind power, Solar PV: Electric Reactor, Inverter etc.

Electrical Equipment:High/low voltage distribution control cabinet, Distribution box Switch Gear.

Power Transmission and Distribution Equipment: bus duct, Transformer etc.
