Nowadays, on the road, electric vehicles are gradually replacing traditional fuel vehicles. The global sales of electric vehicles are growing rapidly. At the same time, the production of electric vehicle charging piles, charging cables and connectors is increasing. Of course, the number of electric vehicles has increased, and the number of uses has increased, with a large proportion of charging cable damage. UL American standard certified cable is the requirement for selecting electric vehicle charging pile cable Standard: It mainly relies on the product standard established by UL's UL62 flexible cable standard. The insulation materials specified in the standard include polyvinyl chloride (PVC), thermoplastic elastomer (TPE), polypropylene ethylene (EPR) and other materials. The sheath materials include PVC, chlorinated polyethylene (CPE), TPE and other materials. There are many types of materials and models in the standard, and the specific structural parameters are mostly consistent with UL's cable products, The standard is relatively broad, without strict restrictions on materials and structures, as long as it can meet the basic performance requirements of the charging cable. One point mentioned is that the selection of charging pile cables is based on the voltage and current requirements at the rated power of the charging pile, and certain safety controls should be reserved. Generally, the AC pile uses a three core cable that meets the requirements of the national standard, while the DC pile uses a five core cable. The specific charging pile manufacturer will have requirements, and the selection should be based on the cable cross-sectional area and the bearing ammeter. The electric vehicle charging cable is the carrier connecting the electric vehicle and the charging pile. Its main function is to transmit electric energy. However, with the progress of charging technology, the electric vehicle and the charging dummy need to communicate, communicate and automatically control when necessary.

With the rapid development of social economy, the number of absolute advantages of electric vehicles has increased rapidly. All regions have charging piles and cable equipment to charge electric vehicles. The electric vehicle charging pile came into being under the general environment of policy and actual situation Application scope and performance requirements of electric vehicle charging pile: the cable of charging pile can be used indoors or outdoors. When used outdoors, the cable of charging pile can meet the corrosion of high cold, sunlight, rain and automotive oil substances. The cable of charging pile has special properties such as anti ultraviolet, ozone, high low temperature and chemical corrosion resistance. The cables of the charging pile can be frequently stretched and bent or crushed by electric vehicles and other external mechanical damages. The cables of the charging pile can meet special mechanical performance requirements, such as bending, bending, rolling test, etc. Conductor type: the conductor is made of multi strands of fine twisted oxygen free copper wire, with strong flexibility. Insulation characteristics: special modified high temperature resistant elastomer material insulation, oil, water and corrosion resistance, high and low temperature resistance, high mechanical strength, excellent chemical stability and dielectric properties, good product performance, and safe use. Applicable environment: - 40 ℃~125 ℃ Applicable products: applicable to car charging pile equipment, mobile portable charging wire and cable device (spring wire series), and electric vehicle internal wire (battery wire)/motor wire.

In the ratio of the earth's sea and land, there are 71% of the ocean accounts for most of the land and 29% of the land. The ships and boats used to are no stranger to people's travel tools, and are known to human beings in six characteristics of ships.
Among them, the first, large size. Many of the container ships are transported back and forth through every day. For example, the average tonnage of container ships has developed from hundreds of boxes in the past to nearly 10,000 boxes at present. Second, high-speed. Within the last 15 years, the average speed of more than 10,000 gross tons of ships increased by about 1kn, high-speed passenger ships, cargo ships, car-passenger ferries and container ships and other development updates, such as speed 50kn roll-on roll-off high-speed five-hull type ship, speed 38kn 1400 boxes of fast container ships, speed 40kn 1000 tons of high-speed wave-piercing cargo ships. Third, the technical performance is constantly upgraded. Firstly, the economy is obviously improved, which is mainly reflected in the simultaneous reduction of fuel consumption and crew number of ships; secondly, the safety and environmental protection are greatly improved to avoid the recurring disasters of sea damage and reduce the pollution of ships to sea water and atmosphere. Fourthly, the design methods keep progressing. Direct design calculation method, ship hydrodynamic performance forecast and optimization technology, new efficient low excitation propeller design technology are widely used, and information networking will be a major technical measure for ship design in the 21st century.
