Carbon Fiber Composite Core Conductor (CFCC Conductor) consists of carbon fiber composite core (CFCC) and the outer trapezoidal aluminum wire. The CFCC is high performance carbon fiber production which combines carbon fiber and resin system. The aluminium wire outside includes soft aluminium, semi duralalumin, and heat-resisting aluminium alloy. The shape can be made into T-type, SZ-type, and circular-type.

Compared with ACSR Conductor, it has series of advantages, including high current carrying capacity, low sag, light wight, high tensile strength, saving costs of towers and decreasing the covering area etc.

1、It is not only able to eliminate core loss and thermal effect through changing hard aluminium into soft aluminium, it can also increase the operating temperature of the conductor, and the cross-section filling rate of the wire. The ampacity has increased nearly twice under the same external diameter compares to Aluminium Conductor Steel-Reinforced (ACSR) Conductor, capacity expansion and double capacity has been achieved.

2、The strength of the core can be over 2400 MPa, and the increase of the safety coefficient makes the conductor has strong icing ability.

3、The core has low coefficient of linear expansion, small change of sag. And the high tension-weigh ratio, witch makes it able to decrease the erection sag, and leads to reduce the height of the tower and save the quantity of it. Also, the tower bare occupation can be reduced, land resource can be saved, and the comprehensive cost of the transmission line can be reduced as well.

4、Good environmental aging resistance performance, lengthy life span. CFCC Conductor doesn’t rust, witch avoid the electrochemical corrosion happens between aluminium wire and galvanized steel when electrify and acid rain corrosion common conductor will face.

5、No gap on outer rage, small external diameter on same cross section, high ability of wind deflection resistance.
