Usage and feature

     High strength carbon fiber composite core compressed aluminum twisted wire is mainly used for aerial wire of power transmission/distribution. Because electric company needs to improve the power transmission/distribution capacity of grid, therefor when build new or re-build old aerial power transmission grid, it can improve effectively the power transmission capacity of grid to use High strength carbon fiber composite core compressed aluminum twisted wire. Its ampacity is twice of steel core aluminum twisted wire. It possesses the capacity to transmit power at high temperature. Its operation temperature may be over 175°C. It may be applied at the condition of 200°C for short time. Nevertheless the operation temperature of ordinary of ordinary steel core aluminum twisted wire is 75°C only.

   The cable is made of arch aluminum wire and carbon fiber reinforced core through twisted. Compared with ordinary steel core aluminum twisted wire, under the condition of equal OD the cross section of aluminum can increase about 28%. The DC resistance will be decreased and the AC resistance is smaller too. Because of high electric conductivity and low resistance characteristic, the loss of electric energy is reduced.

   The compressed type wire has smooth surface and small load of wind pressure while operate. Its surface is not suitable to ice and can reduce winged taken place probability. Meanwhile the space between the space of strands of arch aluminum wire and the space between strand wire and carbon fiber reinforced core is surface contact. When wind stimulates vibration, it can consume dynamic energy, i.e. with good self damp characteristic and can wipe out self damp and other anti-oscillation evict.
