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.

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.

Marine cable, the main use in the ship or offshore construction of power, signal transmission Due to the use of harsher environmental conditions, the cable is required to be safe and reliable, long life, small size, light weight, and has excellent temperature resistance, fire resistance, flame retardant, oil resistant, moisture resistant, seawater resistant, excellent electrical and mechanical properties and other requirements. Marine power cable is a kind of marine cable. Commonly used standards: IEC 60092 series, GB/T 9331 series Similar to the main classification of wire and cable, marine cables can be divided into marine power cables (including rated voltage frequency AC 1kV and below low-voltage power cables and rated voltage frequency AC 3 ~ 15kV medium voltage power cables), marine control cables, marine communication cables, marine signal cables and marine RF cables according to the scope of use. Cable connection equipment purposes, for power, lighting and signal transmission, etc. Cable laying position requirements whether long-term immersion in water, low temperature and the requirements of whether with shielding, etc. In addition, in the working conditions, fixed laying, laying through the tube and moving conditions require special requirements, etc. Need to know more information about special cable products for connecting equipment, you can in the high-voltage cable product promotion page at. |
