The coils of the cable wire are called the glint;
It is called a double stranded wire or a pair of stranded wires.
It is called a triple stranded wire or a three-strand line.
The helical symmetry of the four core wires is called the star capstan pair or the star winding group.
Stranded wire core in addition to the main function of optimization combination line core (each force is equal, round structure, change the distributed capacitance conductor), and make relative said in transmission line core current in different directions, with the effects of the magnetic field, such as offset and the signal transmission.
The main purpose of this is to be based on anti-interference or balancing electric field
