Specifications of wire and cable

The main features of the products are: different specifications, a wide range of applications, the use of voltage 1kV and below more special occasions, in the face ofconstant derived from the new products, such as refractory cable, flame-retardantcable, low smoke zero halogen / low smoke and low halogen cable, anti termite, antimouse hdmi extension cable , oil resistant / cold / temperature / wear cable, medical / agricultural /mining cable, thin wire etc.. With the rapid development of communication industry,from the past simple telephone and telegraph cable development to thousands of words on the cable, coaxial cable, optical cable, data vga extension cable , or even combinedcommunication scart splitter cable etc.. This kind of product structure is usually small and uniformsize, high precision manufacturing. Winding wires is a conductive metal wire insulation layer, is used for winding coil or winding of electrical products. Workthrough an electric current produces a magnetic field, or cutting magnetic line of forceto generate induction current, realize the transformation of electricity and magnetism,so it become the electromagnetic wire. Wire and cat6 cable products is the vast majority ofsection (cross-sectional) have identical shapes (ignoring the error caused by themanufacture), is a long strip shape products, this is because in the system or deviceis composed of lines or coil and used as the feature of the decision. So the study ofstructural analysis of the cable product composition, only need to observe and analyze from its cross section.

The introduction of electric wire and cable

Wires and cables used to transmit electric (magnetic) energy, information and realize electromagnetic energy conversion of wire products, wire and cable generalized also referred to as the cable, special cable refers to insulated 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 the coating layer, the total protective layer and the outer protective layer, the vga cable can also have additional no insulation of conductor. For the transmission of electric (magnetic) energy, information and realize electromagnetic energy conversion of wire products.
General electric wire and cat6 patch panel is also referred to as the cable, special cable refers to insulated 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 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, 12 port patch panel 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 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 24 port patch panelcat 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 cable conductor is still in the "big brother", but people have begun to actively seek alternatives.

How to use the vga cable?

 VGA connector is the output of the analog signal on the graphics interface, VGA (Video Graphics Array) port, also called D-Sub connector. Although the LCD monitor can receive digital signals directly, but many low-end products in order to match with vga extension cable  which uses the VGA connector. VGA interface is a D-type interface, there are above 15-pin space, divided into three rows, each row of five.vga cable interface is the most widely used type of
 Most computer with an external display is through analog VGA interface display image information, the computer digitally generated internally between devices is changing the video card in a digital / analog converter for the R, G, B three primary signals and lines, field sync signal, the signal is transmitted to the display device via a cable. For analog display device, such as an analog CRT display, the signal is sent directly to the appropriate processing circuitry, the drive control tube to generate an image. As for LCD, dvi cable and other digital  display devices, display devices need to configure the A / D (analog? Digital) converter, the analog signal into a digital signal. After a D / A conversion and A/D2, inevitably result in some loss of image detail. VGA interface used in CRT monitors is understandable, but the loss of connection for image display devices like LCD, the conversion process will display a slight decline.interface, the vast majority of graphics cards with such an interface.

Vga extension cable often problems and solutions

An image for a reason flashing fault but more flower color: generally vga extension cable adjustment switch is not adjusted Workaround: use a small screwdriver to slowly adjust with vga extension cable remote control knob to a satisfactory picture of the state of two images, fonts are generally several reasons tailing common fault; 1 crystal head no pressure is good, the contact resistance of the big two remote control switch is not fine .3 . bad quality or network cable network cable over distances using distance and distance and cable quality is generally solution: remote adjustment knob, re-pressed crystal head, use good quality crystal head, make sure to use a good brand of good contact network cable (cat5e patch panel is better), transmission distance and use our recommended brand cable cast serious three-screen, full of red, green, blue, short tail long distance, adjust the switch can not resolve the cause:vga extension cable of VGA interface part is there is poor contact problem, crystal head bad problems, incorrect use shielded cable and crystal head of problem solving: Check VGA connector or replace the vga cable，shaking crystal head, check for poor contact problem and test whether all pass, crush, or redo crystal head. distances shorter tail length is generally shielded crystal head and the network cable is not properly grounded problems, solutions, grounding, and use shielded crystal head four. remote did not chart indications, because light does not fault: Generally it is not connected VGA connector and cable problems and crystal head solution: Check the VGA connector and cable section to determine patency and good contact, check the network cable is connected and the Crystal Head and there is good contact five images twill, striped Cause: general vicinity of strong electromagnetic interference is the solution: open wiring interference interference sources, or use shielded cable and crystal head.

Short HDMI extension cable problems and sloves

Short HDMI crossover ethernet cable (I use this is because I have a Raspberry Pi installed in the chassis).
Whenever I use the cable, I quit a simulator, the screen goes blank. RPI index is still alive, because I can connect to it via SSH.
If I remove the extension cord, plug only ordinary cable, there is no problem.
I did some tests using sudo 'in / opt / VC / bin / tvservice-s', I also found that the resolution does not change back to 1280 × 720, the simulator exit. Stay at 640 × 480.
My extension is 1.3A rated specifications (print) and my mini HDMI cable does not specify any (old). The signal will be cut off at random to my monitor, and refused to pass my HDMI Ethernet extension to the TV to watch.
I changed it up a 1.5 m 1.3 Specifications Rated cable and I have no problem with it.
In short, I will make sure that the HDMI cable is being used on behalf of all the games - no need to spend ££ on the line, though.
