One end of the 400A natural heat dissipation direct current charging cable is connected with a charging gun through a plug terminal, and the other end of the 400A natural heat dissipation direct current charging cable is connected with a charging pile through a copper nose and a plug terminal. Four circles of wires are coaxially and tightly arranged in the insulating jacket of the charging cable, and the number of the four circles of wires is ten, twenty-one, fifteen and six in sequence from outside to inside. The wires of the first circle are thick wires with the same wire diameter, and the two wires of the second circle, the third circle and the fourth circle are thin wires with the same wire diameter. According to the charging cable, the wire diameter of the cable is reduced to the maximum extent on the premise of ensuring the charging power, the wire diameter of the cable is 27.5 mm, the bending radius is reduced to 120 mm, the use experience of a user is improved, and the charging operation becomes easy. Under the same bearing, the charging cable is small in conductive sectional area and large in heat dissipation area, copper materials are saved, anisotropy is eliminated, and the tensile property of the charging cable is improved.
一种400A自然散热直流充电线缆,其一端通过插接端子与充电枪连接,另一端通过铜鼻子和插接端子与充电桩连接;在充电线缆的绝缘外被内同轴紧密排列有四圈导线,四圈导线的根数从外向内依次为十根、二十一根、十五根、六根;第一圈的导线为线径相同的粗导线,第二圈、第三圈、以及第四圈中的两根导线为线径相同的细导线。本充电线缆在保证充电功率的前提下最大限度地减少线缆的线径,将使线缆的线径27.5毫米,弯曲半径缩小至120毫米,提高了用户的使用体验感,使充电操作变得轻松。在同样的承载下,本充电线缆的导电截面积小、散热面积大,不仅节约了铜材,而且消除了各向异性、提高了充电线缆的抗拉性能。
