[0006] Specifically, to avoid stress concentration at right angle and cracking at right angle, every two adjacent and perpendicular edges on the cross section of the conductor are transitioned by circular arc.
[0007] Specifically, the radius of the transition circular arc of adjacent and perpendicular edges on the cross section of the conductor is R1mm-R20mm.
[0008] Specifically, to avoid stress concentration at right angle and cracking at right angle, every two adjacent and perpendicular edges on the cross section of the insulation sleeve extruded outside the conductor are transitioned by circular arc.

[0014] The technical solutions of the embodiments of this utility model will be described in detail below with reference to the accompanying drawings.
[0015] As attached Figure 1 A cross-shaped cable has a conductor 1 and an insulating sleeve 2 extruded outside the conductor 1. The cross-section of the conductor 1 is cross-shaped, and the cross-section of the cable is cross-shaped. The cross-section of the cable is a cross-section that integrates the conductor 1 and the insulating sleeve 2 as a whole. The X-axis of the cross-section of the conductor 1 and the X-axis of the cross-section of the cable are on a straight line, and the Y-axis of the cross-section of the conductor 1 and the Y-axis of the cross-section of the cable are on a straight line.
[0016] A cross-section of a specific cable structure is shown in the attached figure. Figure 2 As shown, every two adjacent and perpendicular sides of the conductor 1 cross-section are transitioned by an arc, and every two adjacent and perpendicular sides of the insulating sleeve 2 extruded outside the conductor 1 cross-section are also transitioned by an arc.
[0017] The radius of the transition arc between adjacent and perpendicular sides on the cross-section of conductor 1 is R1mm-R20mm. Similarly, the radius of the transition arc between adjacent and perpendicular sides on the cross-section of the insulation sleeve 2 extruded outside conductor 1 is R1mm-R20mm. The size of the transition arc radius is mainly determined by the cable's profile dimensions. The larger the cable specification, the larger the arc radius.
[0018] The cross-shaped conductor is made of copper, aluminum, etc., and is drawn by a cross-shaped mold. The mold cavity for extruding the plastic insulating sleeve 2 onto the conductor 1 is also cross-shaped.

Furthermore, those skilled in the art will recognize that, based on the ideas of this utility model, there will be changes in the specific implementation methods and application scope. Therefore, the content of this specification should not be construed as a limitation of this utility model.
