New energy, green travel has become a new way of life, and more and more charging piles appear in life, so the standard electric vehicle DC (AC) charging pile cable has become the "heart" of the charging pile.
As a result of the country's vigorous development and support, according to statistics: before 2015, China had 497 thousand new energy vehicles, plus 62663 vehicles sold in the first quarter of 2016, with a total of 560 thousand vehicles. The corresponding charging infrastructure is as follows: by the end of 2015, more than 3600 power stations and 49 thousand public charging piles have been built throughout the country. In the future development, the use of charging piles will be more and more. Therefore, the standard electric vehicle DC (AC) charging pile cable will become a mainstream in the cable industry.
The standard electric vehicle DC charging pile is commonly called "fast charging". In the process of charging, the input voltage of the DC charging pile is AC380V + 15%, frequency 50Hz, and the output is adjustable direct current, which is directly charged for the power battery of the electric vehicle. The standard electric vehicle AC charging pile is commonly known as "slow charge", and the AC charging pile only provides power output, without charging function, it needs to connect the vehicle charger to the electric vehicle, which is the requirement of the large charge pile cable.
The main cable is mainly produced by special cable, so its standard electric vehicle DC charging pile cable has very high performance. It is mainly used in charging pile system, landing type charge pile and hanging wall type charging pile. The voltage is 1KV (DC), test voltage 6000V/min (DC), fixed laying: 4 x cable outer diameter, mobile installation: 7 .5 x cable outer diameter or smaller temperature range, fixed laying: -50 C ~ 90 C, mobile installation: -40 C to 90 C, oil resistance: good, chemical resistance, acid, alkali, solvent and various hydraulic oil excellent performance, weatherability: resistance to UV, excellent sunlight aging performance, suitable outdoor use. Flame retardancy: conforming to IEC. The special structure is adopted and the specifications can be customized.
Use characteristics:
1, the cable in the charging process of voltage, current and other signal control and transmission network system has high pressure, high temperature resistance, anti electromagnetic interference, signal transmission stability, anti distortion more than 10000 times, wear-resistant more than 50000 times, wear-resistant more than 50000 times, oil resistance, waterproof, acid alkali resistance, UV resistance and other characteristics.
2, product concentricity is good, can reach more than 80%, so that the cable high voltage performance is stable and reliable.
3, the smallest bending of the product is 4D, which is convenient for use in narrow space corner wiring. The product has the characteristics of high flexibility, which is very convenient for vehicle wiring.
4. The rated temperature of the product is 125 degrees centigrade. This is a great progress and improvement for the soft grade insulation material used in one molding. It is very important to ensure the flexible performance of the cable and improve the current carrying capacity of the cable.
