In power engineering, a bundle conductor is a number of conductors in parallel. Power engineering is the sub-discipline of electrical engineering that deals with power systems, specifically electric power transmission and distribution, power conversion, and electromechanical devices. ... En [ [ ciencia ] ] y [ [ ingeniería ] ], los conductores son los materiales de los cuales contenga las cargas movibles [ [ electricidad ] ]. Cuando una diferencia potencial eléctrica se impresiona a través de puntos separados en un conductor, las cargas móviles dentro del conductor se fuerzan para moverse, y una corriente eléctrica entre esos puntos aparece...

Bundle conductors are used to increase the amount of current that may be carried in a line. Due to the skin effect, ampacity of conductors is not proportional to cross section, for the larger sizes. Therefore, bundle conductors may carry more current for a given weight. The word current usually implies a flow or movement. ... The skin effect is the tendency of an alternating electric current to distribute itself within a conductor so that the current density near the surface of the conductor is greater than that at its core. ... American wire gauge (AWG) is used in the United States and other countries as a standard method of denoting wire diameter, especially for non-ferrous, electrically conducting wire. ...

More important, the bundle conductors result in lower reactance, compared to a single conductor. In the analysis of an alternating-current electrical circuit (for example a RLC series circuit), reactance is the transient part of impedance, and is caused by the presence of inductors or capacitors in the circuit. ...

As a disadvantage, the bundle conductors have higher wind loading.

Previously, bundle conductors were thought to be useful only for very high voltage, such as 500 kV. More recently, the advantage has been proven, and they are more common, for 230 kV and 115 kV.
