General electric wire and 21 pin scart cable is also referred to as the cable, special cable refers toinsulated cable. It can be defined as, aggregate is composed of the following parts:one or a plurality of insulated wire core, and their respective may have a coating layer, the total protective layer and the outer protective layer, the 21 pin flat scart cable can also have additional no insulation of conductor. The main features of products: pure metal conductor, no insulation and sheath layer, such as steel core aluminum stranded wire, copper bus, electric locomotive line; processing technology is the pressure processing, such as melting, rolling, drawing, stranding / pressing twist; products are mainly used in suburban, rural, user the main line, switch cabinet etc..

The types of cable conductor

Wire and cable conductor by one or a plurality of mutually insulated and outer insulation protective layer made of, will power or information transmitted from one point to another by wire. The conductor is its core, lost the conduction effect of conductor, cable will lose its value. In the copper and aluminum and other metal conductor as the representative of the "traditional forces, how to resist the" to "aluminum alloy, non fiber, carbon fiber and other new materials" representative of the "new power", it becomes more and more attractive to look forward to. At present, the metal conductor common according to the conductive arrangement, followed by gold, silver, copper, aluminum, iron (steel), but considering the application to the wire and cable connectors conductor on raw material costs and other factors, copper and aluminum are the high cost, especially copper, gold, silver, price is low, conductivity better than aluminum, is the most commonly used cable conductor. Copper conductor with the national standard cable of the oxygen free copper, electric wire and cable industry is a heavy material light industry, according to the relevant statistics show that, wires and cables with copper content of copper consumption accounted for about 60-70%. Copper conductor is a core component of copper core cable, regardless of how changes in external technology, progress, copper conductor costs can account for the total cost of cable head, reportedly as high as more than 75%. With the development of China's copper resources are depleted and the international copper prices rise, although the copper wire and crossover ethernet cable conductor is still in the "big brother", but people have begun to actively seek alternatives. Aluminum mineral resources in China is extremely rich, is one of the world's ten largest bauxite resources in the country, to maintain reserves of 25.03 tons of resources. As early as in 1957, our country has put the "Al generation copper" identified as national technology policy. In twentieth Century six, seventy time, due to copper as strategic materials subject to regulations of trade, a large number of domestic aluminium is used as the main material of conductor transmission cable. However, compared with the copper conductors, pure aluminum conductor conductor resistivity, low melting point, poor oxidation resistance, poor mechanical strength, cause problems often overheat, corrosion, short circuit and so on, in the early ninety's, he gradually withdrew from the low-voltage power distribution market, but there are still used in high voltage transmission field.

Wiring terminals FAQ

1, deformation stitching portfolio digit growth, the main reason is because of the irrational structure of the Falcon lead to the uneven stitching two up and down in front, as shown in the structural design must consider the force and deformation of its splicing Falcon direction. 2, screw anti-out problem, in this regard, I recommend the best Barrier terminal block use of anti neck out, because it is compared with the hoop off avoids anti-mouth screw rod and hoop mouth tolerances annoyance. And reliable construction tolerances easy to control. 3, screws and steel pieces with salt spray test in question after plating, due to the company by 2012 standard thread plating (plating is limited, but much of the thread corresponding coating thickness I think remains to be determined), to solve this problem There are two ways in the plating process under normal circumstances, to choose the right sealer and use of the coating in multiple plating, these two methods are to be covered with the naked eye can not see the screw voids generated. Coating a plurality of times using high cost of electroplating, it is recommended to use the first method, this method is that the key is to study the Plug-in terminal block sealer formulation. 4, insertion force the issue in this regard relates to the content more, it has a relationship with the material, plating, structure and industry applications, the connector industry is an important mechanical performance requirements, plug-in terminal even more so, the choice of materials is limited by the terms of the insertion force conductivity (current) and contact resistance and temperature rise. Here is not to do a detailed description of the plating is mainly affected by the type of coating and plating of whether pre-impact, Generally speaking, in the same material and structure than the first pre-plated compression tableting press and then plated plug power in regard to stability, because after the plating process is the invisible material made of hardened metal , and just prior to pressing to eliminate this phenomenon. The main consideration is the structure of the contact pressure plate and lead the needle, needle and tablet lead exposure, mostly in line contact, which resulted in an instant when suddenly appeared with a big plug, and then suddenly smaller, to customers in process used in a very unstable feeling, affecting their life, if the contact pressure plate and lead the needle into surface contact structure, then not only solve the problem of insertion force and reduces contact resistance and temperature l.
