新车电线布线,旧车保养换线都会遇到导线截面的正确选择问题。选择合适的截面既有利于电器设备的正常性能,又有利于导线的耐久性,可靠性,而且对节约钢材也有重要意义。汽车用电线按用途有低压线高压线以及起动机线。本文讨论低压导线截面的选择。1．导线的电压损失导线输送电能时,由于存在电阻会产生一定的电压损失,它与输送电压高低有关,汽车电系都属于低
New car wire wiring, used car maintenance line will encounter the correct choice of wire cross-section issue. Select the appropriate cross-section not only conducive to the normal performance of electrical equipment, but also conducive to the durability of the wire, reliability, but also to save steel is also of great significance. Automotive wire according to the purpose of using low-voltage high-voltage line and starter line. This article discusses the selection of low-voltage wire cross-sections. 1. The voltage loss of the wire When the wire delivers the electric energy, there is a certain voltage loss due to the existence of the resistance, which is related to the level of the transmission voltage, and the car power system belongs to the low
