A natural heat dissipation 350A direct current charging cable is characterized in that three circles of wires are coaxially and tightly arranged in an insulating jacket, the number of the three circles of wires is 11, 16 and 4 in sequence from outside to inside, and the diameters of the wires in the same circle are the same; in terms of functions, the ten thick wires in the first circle are charging wires, and the remaining thick wire is a PE wire; the eight thin wires in the second circle are charging signal wires, and the remaining eight thin wires are auxiliary power lines. And the four wires with shielding protection in the third circle are charging communication wires. 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 reduced from 38-41 mm to 23-26 mm, the bending radius is reduced from 230 mm to 110 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.
一种自然散热350A直流充电线缆,在绝缘外被内同轴紧密排列有三圈导线,三圈导线的根数从外向内依次为十一、十六和四,且同圈内导线的线径相同;从功能上区分,第一圈中的十根粗导线为充电线,剩余的一根粗导线为PE线;第二圈中的八根细导线为充电信号线,剩余的八根细导线为辅助电源线;第三圈中的四根具有屏蔽保护的导线为充电通讯线。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,将使线缆的线径由38‑41毫米缩小至23‑26毫米,弯曲半径由230毫米缩小至110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。
