Charging cable as a connection between electric vehicles and charging pile current carrier, safety issues have been the concern of the public groups, both the need to carry out the information transmission between the two, but also to control the charging, but also to ensure excellent insulation performance based on the characteristics of the circuit has a high aging resistance, heat resistance, oil resistance, weather resistance, etc., because in the process of use often to bend, dragging, so also Require the flexibility and mechanical properties of the cable.

Generally, according to the charging power rating, there are two types of home charging posts: 3.5kw and 7kw, the rated current of 3.5kw charging post is 16A, and the rated current of 7kw charging post is 32A. Both power charging posts are connected to 220 volt single-phase household electricity.

Product Application: Electric vehicle charging cable where the AC cable is used for AC rated voltage 22V electric vehicle conductive charging interface connection cable. Suitable for home or public places to use the power supply equipment configured to control the conduction circuit to provide AC charging power for electric vehicles, is the charging cable products used routinely for electric vehicles.

Product features: high temperature resistance, flame retardant, good oil resistance, anti-abrasion, high mechanical strength, high softness and flexibility, easy to install and easy to use. Flame-retardant materials usually contain heteroatomic polymer materials, such as those containing elemental bromine and phosphorus, which absorb the free radicals generated by combustion during the test combustion process and hinder the chain reaction. It will not burn itself and prevent the propagation of combustion. High temperature resistance indicates that the original properties are still maintained under high temperature conditions, such as the Hooke coefficient when stretching, material wear resistance, sealing, etc. It also means that under high temperature conditions, its chemical properties will basically not change, while trying to ensure that the physical properties do not change.

Oil resistance is mainly used to test the ability of the material to resist oil corrosion, such as the material made of standard samples, put a certain amount of time soaked in the oil to be determined, and then seek the product volume growth or the amount of change in quality, by the test to determine the product oil resistance.
