3V3 high current cable generally refers to a cable used for 3V voltage and capable of carrying a large current.
This type of cable needs to have a lower resistance to reduce the loss of electrical energy during transmission. Usually its core is thicker, because according to Ohm’s law (I=U/R), under a certain voltage, in order to pass a larger current, it is necessary to reduce the resistance of the cable, and a thicker core can effectively reduce the resistance.
In terms of material, copper and other materials with good conductivity are mostly used. The conductivity of copper is second only to silver, and the cost is relatively more appropriate, which can ensure the safe and efficient transmission of large currents at 3V voltage. At the same time, the insulation sheath of the cable is also critical. It needs to have good insulation, wear resistance and corrosion resistance to ensure safe use and cable life.
