Brief Introduction of Carbon Fiber Composite Core Conductor

The specific gravity of carbon fiber composite material is 1/4 of steel's, its tensile strength is 2 times than steel's and its coefficient of linear expansivity is 1/10 of steel's. Due to its excellent mechanical properties and thermostability, it is firstly applied in the military field such as spaceflight, aircraft and lose weight of armament and subsequently used for the equipment of civil aircraft and competitive sports. By the solution of large scale production of carbon fiber technique, carbon fiber composite material begins to enter the field of industry and life.

For a long time, overhead conductors are mainly ACSR and other related products. With the rapid development of the power industry, the requirement for overhead conductors is becoming higher and higher, which urges scientists to research and develop all the kinds of new-type conductors. In order to improve the sag characters, people try to replace metal material with composite material to make the strengthening core of conductor in the later 1990s, so as to increase the capacity of transmission line.

Advantages of carbon fiber composite core conductor (Compared with the ACSR):

The weight is less and the strength was higher, so the sag is smaller on the same operating stress;
The coefficient of linear expansivity of conductor is smaller, so the variation of sag is smaller from the lowest temperature to the highest temperature;
The outer diameter of conductor is smaller, so the ice load and wind load are smaller during operation;
The D.C resistance and A.C resistance of conductor are less, so the line loss is less during power lines operation;
The maximum continuous operating temperature of conductor is 180℃, which is much higher than ACSR's, so the carrying capacity can almost double;
The corrosion resistance is excellent, so the service life is longer;
The surface of conductor is compact and smooth, the corona loss is lesser;
The model (the cross-section of aluminum and composite core) can be designed according to actual engineering needs.

The mechanical, thermal and electrical properties of carbon fiber composite core conductors are superior to traditional conductor, which synthetically resolve all the technical bottleneck in the field of overhead power transmission and can be widely applied to the reformation of capacity expansion for old power line, construction for new power line and power station bus line. Moreover, they can also be used for the power lines with large span, large fall, heavy icing area, heavy pollution and other special climate and geography areas. Therefore, carbon fiber composite core conductor has obvious economic and social benefit for the old or new power lines construction.

ISO: Including ISO 9001 quality management, ISO 14001 environmental management and other related standards.
ASTM (American Society for Testing and Materials): Provides test and material standards applicable to cable performance and safety.

Our company's advantage for this carbon core aluminum conductor is that we have professional supporting testing machines comparable to those of the cable institute's third-party institutions to perform tensile and bending tests on aluminum and cores. We have 100% test data throughout the entire production process.

And we can ensure that this CFCC conductor is produced in a constant temperature environment. This ensures the safety of the product and eliminates the possibility of quality problems.Customized packaging tray length also provide.

Our factory -Far east which specializes in doing R&D, production and sales of carbon fiber composite core conductor in 2006.

The reference standards of carbon fiber composite core conductor are ASTM B609, ASTM B857, ASTM B987 and other international advanced standard. The type of carbon fiber composite core conductor is JLRX1/F1B(ASTM) ( J-Over head conductor, LR-Full Annealed aluminum, X1-Trapezoidal Wire, F1B-carbon fiber composite core, ASTM-Reference standard of composite core is ASTM B987/B987M), which is represented by the nominal cross section of aluminum and composite core. Electric aluminum is full annealed aluminum, whose conductivity is more than 63% IACS and its cross section is designed to be trapezoidal-shape, which can reduce the outer diameter of conductor greatly.
