The results of table 2 show that when the included angle between the front end face of the power transmission aluminum piece and the vertical plane of the axis is greater than 5 degrees, the drawing force value of the power transmission aluminum piece is in a descending trend, and the mechanical property of the power transmission aluminum piece is reduced accordingly. The voltage drop value of the electric energy transmission aluminum piece is increased, and the electrical performance of the electric energy transmission aluminum piece is reduced. When the included angle between the front end surface of the electric energy transmission aluminum piece and the vertical plane of the axis is larger than 15 degrees, the drawing force value and the voltage drop value of the electric energy transmission aluminum piece do not meet the requirements of mechanical property and electrical property of the electric energy transmission aluminum piece. Therefore, the smaller the included angle between the front end surface of the electric energy transmission aluminum piece and the vertical plane of the axis is, the more ideal the voltage drop and the drawing force of the electric energy transmission aluminum piece are.

The results in table 3 show that when the compression ratio of the aluminum core is less than 35% and greater than 97%, the drawing force value of the aluminum piece for power transmission is in a descending trend, the drawing force is lower than 200N, and the mechanical property of the aluminum piece for power transmission is also reduced; and the voltage drop value of the electric energy transmission aluminum piece begins to rise, so that the electrical performance of the electric energy transmission aluminum piece is influenced. When the compression ratio of the aluminum guide core is 35% -97%, the voltage drop and the drawing force value of the electric energy transmission aluminum piece are within a more ideal range value.
