In fact, there is no strict boundary between wires and cables. Generally, products with few cores, small diameter and simple structure are called wires, those without insulation are called bare wires, and others are called cables; The conductor with larger cross-sectional area (more than 6 mm2) is called large wire, the smaller one (less than or equal to 6 mm2) is called small wire, and the insulated wire is also called cloth wire. The wire is composed of one or several soft wires, which are covered with a light and soft protective layer; The cable is composed of one or several insulated conductors, which are wrapped with a tough outer layer made of metal or rubber. Cables and wires are generally composed of three parts: core wire, insulating sheath and protective sheath. The characteristics of common cables are as follows: CEF - ethylene propylene rubber insulation, neoprene sheath, marine flame retardant power cable. CVV - PVC insulated, PVC sheathed marine flame retardant power cable. BV, BX, RV and RVV series wires are often used for oxygen cabin wires, including: Bv - copper core PVC insulated wire, with long-term allowable temperature of 65 ℃, minimum temperature of - 15 ℃, working voltage of AC 500V and DC 1000V, which can be fixed indoors and outdoors, and can be laid in open or concealed. BX - copper core rubber insulated wire, the maximum service temperature is 65 ℃, which is applied indoors. RV - PVC insulated single core flexible wire, with maximum service temperature of 65 ℃, minimum service temperature of - 15 ℃, working voltage of AC 250V and DC 500V, used as internal wiring of instruments and equipment. RVV - copper core PVC insulated and sheathed flexible wire. The allowable long-term working temperature is 105 ℃, and the working voltage is 500V AC and 1000V DC. It is used in wet, high mechanical protection requirements, frequent movement and bending.

The high voltage system of electric vehicle has high voltage and high current circuit. Its safety and importance are self-evident. If human body contacts, it may cause injury. Therefore, the design and layout of high voltage harness of electric vehicle is very important. In addition, green travel is a concept advocated now. Now the short-distance public transport travel mode is gradually replaced by new energy vehicles, which requires higher requirements for the high-voltage cables of new energy vehicles. Here is a brief introduction to the high-voltage cables of new energy vehicles. High voltage cables are mainly composed of sheath, braid and tape, conductor and insulation (from outside to inside). Of course, considering the harsh environment where high-voltage cables are located, the requirements for different places are also different. For voltage: the main difference from common automobile cables is that the frame needs to be set according to the rated voltage of 600V. If it is applied on commercial or bus, the rated voltage can reach 1000V, which may be higher than that; The cables now used in cars driven by internal combustion engines are designed to have a rated voltage of 60 V; For temperature: at present, in addition to the higher temperature sent to the engine room or high temperature cabin in the vehicle, the withstand temperature of other electric furnaces often used is up to 105 ℃, while the high-voltage cables used in new energy are usually higher than the ordinary value, such as 125 ℃ or 150 ℃. Different places have different requirements for cables. Service life: the recognized cable standard is 3000h, which is often used in long-term aging test. There will be special requirements for those used in the high-voltage field, which may exceed 3000 h, and the cumulative operation time at the specified temperature may even reach 12000 h; Safety signs: high voltage power will bring certain risks to users. High voltage cables should be visually distinguished from ordinary cables, and safety warning signs should be marked at the same time.

The electric vehicle charging cable is used to connect the electric vehicle charging device and charging infrastructure, so as to transmit power to the electric vehicle, and is equipped with a certain number of signal lines, control lines, power auxiliary lines, etc. to ensure accurate control and safe operation of the whole charging process. Charging cables are generally used in charging stations, parking lots, hotels, communities, garages and other areas. Portable charging cables can be placed in the car.
How many square meters of cables does the electric vehicle charging pile need? The thickness of the wire harness of the charging pile cannot be unified, which is mainly determined by the power storage capacity of the charging pile and the voltage borne by the wire harness when the power flows. Specific wire and cable specifications can be found on the official website.
