Single-phase Or Three-phase Charging Cables For New Energy EVs

Single-phase cable generally refers to a cable that has one phase conductor and one neutral conductor. This type of cable is commonly used in domestic, commercial, and industrial applications to carry alternating current. Single-phase cables are commonly used on low-power equipment and small appliances. //1

Single-phase cables can be selected from different specifications of conductors and insulation materials according to different power requirements and uses. Usually, the conductors of single-phase cables are made of copper or aluminum, and the insulation material is usually a high-temperature resistant material such as polyethylene or cross-linked polyethylene. //2

Three-phase cable is a cable with three phase conductors and a neutral conductor. It is usually used to transmit three-phase alternating current and is used in large industrial equipment, commercial buildings and large power systems. //3

Three-phase cables typically consist of three phase conductors and a neutral conductor, each typically colored red, yellow, blue, and black. These wires are usually made of copper or aluminum, and the insulation is usually a high-temperature-resistant material such as polyethylene or cross-linked polyethylene. //4

Features: Single-phase electricity, as the name suggests, has only one phase wire, and its wire is composed of a live wire and a neutral wire; //5

Three-phase electricity has three phase wires, and its wires include three live wires and one neutral wire, that is, three-phase four-wires. //6


Of course, the main difference between the two is that the AC voltage is different. Single-phase power is 220V, which is mainly used for home power or office computers. Three-phase power is 380V, which has advantages in power generation and power conversion. It is generally used Suitable for power distribution or higher power equipment, such as industrial scenarios. //7
