Whether it is in power system, information transmission system, or electrician equipment, electrical instrumentation and other fields, the application of cable technology occupy a large proportion, then the world's top five cable technology what are the top?
1, the United States R & D set storage and transmission as one of the nanowires
Central Florida University recently developed a set of storage and transmission as one of the nano-wire. A thin layer of plastic sheeting is added around the nanowhiskers formed on the outer layer of copper wire and wrapped with a metal sheath. Finally, a special gel is used to bond the layers together. Because nanowhiskers are insulated, so while the internal copper retains the conductive function, the copper outer layer can also store power separately. The technology can be directly applied to the field of electric vehicles, space launch vehicles and portable electronic devices, which will help to reduce "weight" and reduce costs.
2,42 new cable installation tools come out
Southwire has introduced 42 new cable installation tools to meet the needs of custom installations. This VDV tool further complements the product range of its low-voltage cable product lines and related tools and equipment lines. It is reported that this is a product-based approach to the development process of installation, to improve the efficiency of on-site installation of cable products. The company launched 42 new cable installation tools including cable cutters, wire strippers, crimpers, wire bonding tools, cable testers and testers.
3, copper transmission rate refresh 100Gbps record
Bell Laboratories uses a single pair of copper wires to achieve 1Gbps symmetric transfer rate within 70 meters and 100Gbps transfer rate within 30 meters using double pairs of copper wires. The copper transmission rate refreshes 100Gbps records. This result, known as XG-FAST technology, is an extension of the G.fast technology. The technology to increase the transmission frequency to 500MHz, but shorter than the G.fast protocol standard shortened a lot, only in a relatively short distance to achieve relatively high-speed transmission. Fiber-optic home access to improve home network transmission, or to improve the transmission rate within the community. This year is expected to launch the official version of the technical standard.
4, South Africa R & D portable devices to protect the submarine cable from sharks
South Africa's latest research and development of a new device sharkpod can protect submarine cable, divers, etc. from the sharks. The device uses the "Shark in the deep sea can capture the heartbeat of quarrels sent by the current" This feature only when the shark near the current barrier to change the direction of departure, you can not harm the sharks, seals, dolphins and other organisms based on the protection Submarine cable, personal safety. It is reported that the device will be piloted on the sea cable for 5 months, after more large-scale experiments will be carried out. There are already Australian companies to start selling, the device adds a layer of protection for the undersea cables, if the success is expected to promote worldwide.
5, smart cable protection technology to reduce costs and increase reliability
DNVGL, an energy consultancy and testing organization, announces a smart cable protection solution that continuously monitors and detects the exact location of a medium voltage (MV) power cable system failure. The program provides real-time insight into cable updates, shortens repair time, increases the stability of medium voltage power cable systems and reduces overall service costs for utility and industrial asset owners.
This is the Y83 series horizontal double master cylinder Briquetting Machine. This metal briquetting machine can process a large amount of crushed material including cast iron, steel, aluminium, copper and brass, as well as a mixture of grinding slurries and metal chips.
