Optional elements of cable

Wire and plug in terminal block as the main carrier of power transmission, are widely used in electrical equipment, lighting, household appliances and other lines, its quality directly affects the quality of the project and the life and property safety of consumers. There are a lot of wire varieties on the market, want to use the appropriate wire according to the power load your.
On the market sell wire some cheap and some more expensive, some people often but to relatively cheap, cheap, wires, often have many did not reach the performance that he shows, there may bring many security hidden trouble to yourself. Production technology content of wire is not too high, the raw material is not much difference, if cheap too much, or cut corners, or the number of not giving enough. How to identify it. I give you several methods for easier identification:
1, to look at the packaging, GB wires tend to do relatively well, neat, hand up have a sense of quality.
2, to open the package to see the inside of the wire, the wire GB 1.5 - -6 square wire requirement is thick skinned (insulation thickness) is 0.7mm, too thick is non-standard, corresponding to his inner core is sure enough, line skin you can force pull, not easy to tear is general is the national standard of
3, with the fire, extinguished within 5S after leaving, have certain flame retardant function for GB line.
4, look at the inner core, the inner core material (copper) brightness higher copper is better, and photometric mini hdmi cable uniform, shiny, no sense of hierarchy. The national standard requirements within the core must use oxygen free copper. Non standard such as black rod copper, there may be hidden dangers of accidents.
5, the thickness of inner core countries have certain requirements, but not very strict. But not a lot of mistakes, only a very small a little bit error generally with the eyes of the.
6, length, no compulsory must play meters, but there are many manufacturers also played meters, not necessarily GB dozen meters, but the General GB generally not dozen meters. Non standard dozen meters that is only a kind of means.
7, the provisions of the state on the wires must play a certain identity, the maximum not more than 500mm have identified the same next play out, above the general product trademark, factory name, the implementation of standards

HDMI and DVI digital signal processing WISDOM mini hdmi cable effects are exactly the same

HDMI and DVI digital signal processing effects are exactly the same, they are all derived from the same standards out of the interface. Difference is that HDMI is connected with audio, and DVI generally crossover ethernet cable do not, under special circumstances can be achieved, but the effect is not good.So, if your monitor with speakers, be sure to HDMI, otherwise no sound. If not, then see if you have a graphics card and monitor are what interface to connect directly without conversion as well. If you have HDMI, has DVI, but no speakers under the display cases, individuals tend to DVI, since HDMI is designed to push the kind of the kind at any time, the rj45 modular jack connection is not solid, in terms of desktops someday thread out also very depressed. In addition, HDMI audio signals that the road will be useless interference somewhat, but it is slightly worse than the actual DVI is almost impossible to distinguish.
The above statement refers to a common DVI-i other DVI-d DVI-A are not taken into consideration, because the general graphics card with HDMI, DVI-i's are up.

the difference between mini hdmi cable with ordinary wire is mainly the larger cable size

1, the difference between the material
  Wires for carrying electric current conductive metal wire. There ﹑ stranded solid braided or foil and other forms. Divided by the insulation condition bare wires and insulated wires into two categories. Cables insulated from the one or more mutually insulated conductive wire cores placed in the sealed configuration of the sheath. An outer protective cover WISDOM utp cable  layer may be added, that the difference between the wire and cable wire size is generally small, the structure is simple, but the cable may also be included in the sequence of generalized wires.
2, the difference between the use of
  Does not include any bare wires wire insulation or protective layer. In addition to the wire as the transmission of power and information, but also for the manufacture of motor ﹑ electrical components and cables. General use of copper, aluminum, copper alloy ﹑ aluminum. In addition, there are a variety of special requirements applicable to insulated  wire, such as a car with a high-pressure low-voltage wires, automotive ignition  WISDOM Mini HDMI cable lead wire electrical appliances ﹑ ﹑ ﹑ aviation conductor wires and other compensation. Cables for the transmission or distribution of electric energy ﹑ send electrical signals. Cables can be divided according to their use of power cables, lines, communication cables and control cables.
3, the difference between the structure
  Power cables and wires of common difference is mainly the larger cable size, the structure is more complex. Cable mainly consists of the following four parts group. Flex Heart: with high conductivity material. Insulation layer: as the cable insulation material should have a high insulation resistance, high breakdown electric field strength. Often the cable insulation material classification.
 In addition to the above differences, the cable also has a WISDOM hdmi wall plate  distinct advantage. Compared with overhead lines, the advantage is that the cable insulation distance between lines of small, small footprint, without accounting for the laying of underground space above ground, the impact of environmental pollution from the surrounding, power transmission and high reliability, safety and the environment for interference small. Thus, cable and more used in densely populated areas and dense grid congestion and busy place. For modernization have a negligible effect.
