As the current carrier connecting the electric vehicle and the charging pile, the safety of the charging cable has always been the concern of the public. It not only needs to transmit information between the two, but also control the charging. On the basis of ensuring excellent insulation performance, the circuit has high performance of aging resistance, heat resistance, oil resistance and weather resistance, Due to the frequent bending and dragging during use, the flexibility and mechanical properties of the cable are also required.



Generally, according to the charging rated power, it can be divided into 3.5kw and 7KW household charging piles. The rated current of 3.5kw charging pile is 16a and that of 7KW charging pile is 32A. The charging piles of these two powers are connected to household 220 volt single-phase electricity.



Household charging piles are normally connected to 220 V single-phase electricity, but the power and current are different. The cables connected to electricity and air switches are different. A 3.5kw charger or charging pile is connected with a 4-square cable. Normally, the line connecting our household electricity to the air conditioner is 4-square. If it is a portable ground free charger, the 3.5kw charger can be directly plugged into the air conditioner socket for charging. If it is a charging pile, it should be connected with a 4-square cable (if the distance between the power meter and the parking space is too far, it is recommended to use a 6-square cable). When a 7KW charging pile or charger is used alone, a group of cables shall be connected with at least 6 square wires or more, and the ground wire must be connected. If the wiring distance is far, it is recommended to use 10 square wires. In order to be safe, the cost of a 10 square line and a 6 square line is not much different.

In addition, the rated current of 7KW household charging pile is 32a, and the air switch connected to the line requires 40A or 60A. If the line is over-current or over-voltage, the air switch can play a protective role in time.
