New energy and green transportation have become a new way of life, and more and more charging piles appear in people's lives, so the standard EDC (AC) has become the preferred choice of charging piles.“heart”. Data show that with the strong support of the state, the number of new energy vehicles in China has reached 497,000, and the sales volume in the first quarter of 2016 was 6,263, a total of 560,000. Correspondingly, the construction of charging infrastructure is as follows: by the end of 2015, more than 3,600 charging and swapping stations and 49,000 public charging piles had been built nationwide. In the future development, the use of charging piles will increase. Therefore, electric DC (AC) charging pile cables will surely become the mainstream of the cable industry. Generally, DC charging piles for electric vehicles are generally called fast charging. Electric vehicle power supply, electric vehicle power supply, direct charging, input voltage 50Hzac380V±15%. Able to meet fast charging requirements, AC charging piles for standard electric vehicles are usually called“slow charge”, The AC charging pile only provides power output and has no charging function. It is necessary to connect the vehicle charging motor to the electric vehicle for charging. This is the requirement of the charging pile for the cable. Standard DC charging pile cables should be equipped with excellent charging piles, floor charging piles, and wall-mounted charging piles, the voltage of which is 1KV (DC), the test voltage is 6000V/min (DC), fixed laying: 4×Cable outer diameter, setting: 7.5×The outer diameter of the cable or the temperature range is small, and the fixed laying is carried out at the temperature of -50~90°C, and the movable equipment: -40~90°C. Fire performance: in line with IEC. With a special structure, the specifications can be customized. Use characteristics: 1. It has the properties of high pressure resistance, high temperature, electromagnetic interference, stable signal transmission, 10,000 times of bending, 50,000 times of wear resistance, 50,000 times of wear resistance, oil resistance, water resistance, acid resistance, and ultraviolet resistance. 2. The concentricity of the product exceeds 80%, which makes the cable's high-voltage resistance performance stable and reliable. 3. The minimum bending of the product is 4D, which is convenient for use between corner lines in narrow spaces. The product is highly flexible, and the vehicle wiring is very convenient to use. 4. The calibrated temperature of the product is 125°C. It is a major technological progress and improvement for the use of one-time molding soft grade insulating materials, and it is very important to ensure the flexibility of the cable and the ability to increase the current carrying capacity of the cable. .
