Network cabinets network layout principles are those who do? Network cabinets network layout first need to pursue practical, depending on how much room we have to size and equipment to carry out the specific implementation .Network cabinets need to pursue a comprehensive network layout Secondly , during the process of networking , network cabinets and RAC CABLE server cabinets and other equipment placement should be integrated, network layout to be thoughtful , try to make a variety of devices and cabling system in a reasonable position ;
Network cabinets network layout again need to pursue reliability , network cabinets network layout final aim is to enable normal functioning network cabinets , network cabinets made if the network can not operate normally after the layout , then do preliminary work will become useless. Finally, network cabinets network layout need to pursue ease of maintenance and upgrades. As the group Netcom network often is not static, it is constantly improving and expansion ; in the daily operation and maintenance of the network , the network layout planning should take into account the future to facilitate network maintenance and upgrade operations.the mini usb cable security level on network cabinets
Electronic chassis network due to power relations is very large, so that in order to protect its owner good use of effects and safety of the process we need to be the appropriate level of security settings , let's take a look at the different levels of electronic chassis cabinets What are the requirements . Learn more four Fangyuan Bo network cabinets product news , please visit : network cabinet
1, for the invasion of dripping condensation water can cause a corresponding formation of the cabinet so as to bring the surface electronic chassis corrosion . So we want to avoid dripping existence appears.
2 , relative to the dripping water spray is probably more damaging , and in order to prevent harm spraying process we need to control the spray angle below 60 degrees.
3, for the drip angle control we also need to control the tilt of 15 degrees or less to reduce the harm of electronic chassis cabinet.

Wire and cable occupational dependence on capital is relatively large
Wire and cable occupational dependence on capital is relatively large. Affected by copper , aluminum, plastic and other raw materials quoted , cable production companies facing cost pressures endless . Shortage of funds , capital chain tight become an important factor in small and medium sized cable company to carry out . Followed by shopping increasingly fierce competition , the cable company's mergers and acquisitions , capital combine to Terminal BLOCK become an inevitable trend. Electric floor heating

Production equipment is the company's fixed assets, the company is also an important resource . And each company produced commodities, many transactions are incidental , not often attack. Thus , the company 's production facilities on the president some time aside. Hold the largest resource spoil . So the company must carefully analyze usage of the equipment , the company's production equipment , production lines combined .
China Wire and Cable how to open up the mall puzzle ?

When China opened up many companies abroad mall hours , we found that in addition to a series of foreign trade barriers maintenance , but also tend to develop norms through skill set of skills barriers. Skills barriers so Chinese companies pay the same to meet the cost of production and marketing costs. Wind power, nuclear power , photovoltaic composite grid smart grid and other cutting-edge products are not involved in the early national standard .

The main introduction of high-temperature wire and cable
Wire and cable as the primary carrier of electricity transmission, widely used in electrical equipment, lighting circuits, appliances, etc., its quality directly affects the quality of life and property safety engineering and consumers. In the market there are many varieties of wire, according to their electricity load to adopt appropriate wires. The Network Cabinet wires on the market to sell some cheap and some expensive, some people tend to be less expensive, but cheaper wires, tend to have a lot of that kind of performance can not reach his description, it is possible to bring their own Many security risks. Production technology content is not too high wire, raw materials also is not much difference, if cheap too, or is cutting corners, or is the number does not give enough. How to do that to sign it. I'll give you that is relatively easy to sign several other ways:
A look to see the packaging, national standard wires tend to do better, neat, holding up a quality feel. 2, to open the package to see what the inside of the wire, the national standard wire 1.5 - 6 square wire requirements are thick-skinned (insulation thickness) is 0.7mm, thick is non-standard, and the corresponding his inner core would certainly enough, you can pull the hard-line leather look, is not easily torn country in general is the subject of
3, what with the fire, extinguished after leaving the 5s, there are certain features of flame marking for the country.
4, see the inner core, the inner core material (copper) copper higher the better brightness and luminosity uniform, shiny, no VGA CABLE layering. GB must use oxygen-free copper core requirements. Non-target such as black copper rod, there may be accidents. 5, the thickness of the inner core of countries have certain requirements, but not very strict. But a lot wrong, just a little small, generally do not come out with seeing the error.
6, length, some countries do not have mandatory fight meters, but there are a lot of manufacturers have played a meter, the meter does not necessarily play a national standard, but the general GB generally do not play m. Non-target hit meter that is only a means.
7, the wire must fight the state has a certain identity, no more than 500mm will have the largest next play out the same identity above generally have a trademark, manufacturer names, such as the implementation of standard products

UK Analysis terminals used in the power transformer industry
Transformer is an electromagnetic induction interaction , changing the voltage , current and impedance devices. The main function of the transformer are: voltage conversion ; current conversion , impedance conversion ; isolation ; regulator (magnetic saturation of the transformer ) and the like.
Classification commonly used transformers can be summarized as follows : ( a ) by way of cooling : ( 1 ) dry-type transformers : to rely on natural air convection cooling or cooling fan increases , mostly for high-rise buildings , high-speed charging station and local lighting electricity , electronics lines and other small capacity transformers. ( 2 ) oil-immersed transformers : to rely on oil as a cooling medium , such as oil-immersed self-cooled , oil -cooled , water-cooled oil , forced oil circulation.
( B) the winding in the form of :
( 1 ) two-winding transformer : used to connect two power system voltage levels . ( 2 ) three -winding transformer : general area substation for power systems , connecting three voltage levels . ( 3 ) auto- transformers : used to connect different voltage power systems . Can also be used as an ordinary step-up or drop after the transformer . (C ) by the core form of : ( 1 ) core-type transformer : used for high-voltage power transformers . ( 2 ) amorphous alloy transformer : amorphous alloy core transformer is new magnetic materials , load current drops to about 80% , is the ideal energy-saving effect of distribution transformers , especially for rural and developing areas such as power grids lower load rate place. ( 3 ) shell -type transformers : Special transformers for high-current , such as electric transformers, welding transformers ; or used in electronic equipment and television , radio and other power transformer Shanghai Hongzhi - box-type transformers. The new UK terminals of the transformer, has been widely used in electrical and electronic engineering industries in the world : large transformers. Transformer terminals, taking into account the structural design easy wiring, screws securely connected features , you can quickly and easily installed on 2X10mm rail . Dedicated transformer is an electromagnetic induction interaction , changing the voltage , current and impedance devices. The main function of the transformer are: voltage conversion ; current conversion , impedance conversion ; isolation ; regulator (magnetic saturation of the transformer ) and the like.
