CFRT Cable Core
Aluminum conductor steel reinforced (ACSR) is easy to sag under high temperatures. It sags severely once the temperature is over 70℃. Sags may cause short out, and even drag the cable down to the ground, endangering the lives of people.
Aluminum conductor carbon fiber (ACCC) is effective to control sags of overhead cable lines. In 2005, the company CTC Global launched the first commercial ACCC wire. The strength and current transmission capacity are twice that of ACSR, while the line loss is reduced by 25% to 40%. The cable core made of carbon fiber is 28% finer than steel cores. It means ACCC can carry AL cables 28% more than ACSR. Thus the current passing capacity is undoubtedly increased.
