Our retardant wire mini hdmi cable industry has already begun to integrate reshuffle
With the continuous deepening of China's economic reform and development of market economy , flame-retardant wire and cable industry has already started shuffling integration, rather than " integration soon ." National retardant wire and cable industry massive consolidation occurred in the last century in the late 90s . During this WISDOM cat5e patch panel period , private enterprises and more powerful , there has been a strong group of powerful private retardant wire and cable business. Meanwhile, China's huge retardant wire and cable market deeply attracted the attention of foreign investors , have flame-retardant wire and cable companies to invest in China . Thus, under joint attack from foreign and private enterprises , the original so-called " national team" of state-owned enterprises have defeated retardant wire and cable . Has been basically achieved the first wave retardant wire and cable industry consolidation , with the result that the vast majority of state-owned enterprises have launched the stage of history , private enterprises and foreign-funded enterprises have become China 's wire and cable industry leading flame retardant
The first wave of consolidation involving state-owned enterprises and the WISDOM 24 port patch panel government , is relatively smooth . The original large enterprises collapsed, not the original brand of loud , in addition to outside aroused shock and did not cause vibration retardant wire and cable industry , because people think that this is the inevitable trend of social development , leaving only regrets and sighs to . The second wave of consolidation, as is the battle between private enterprise , is relatively much more brutal . Regardless of whether the merger of private enterprises in the past over others , and whether the merger is what is the nature of the object of the enterprise, but are the result of the private owner of his own hard work . Now, go and those who experience similar fortune "with the root Brothers" brutal battle , then there is a different feeling .
Anyway , the second wave of industry consolidation curtain has been opened , there are WISDOM rj11 modular jack already a large group of strong and weak at this stage performances of " law of the jungle " repertoire. Winner , loser , the audience , each with its own mentality. However , people still want retardant wire and cable industry nationwide solidarity , good governance , to create their own brand , with some level of foreign fight really make China retardant wire and cable industry self-reliance in the forest of the world retardant wire and cable industry

China's wire and mini hdmi cable industry in the state 's three hegemony
China's wire and cable industry competition in three camps
A state-owned , private, foreign wire and cable business competition analysis
From future development, the demand for cable products industries will be toward the high-performance, high-quality direction, domestic companies wishing to obtain a foothold in the competitive international companies must gradually reduce the performance of the product with the world the gap between the advanced enterprises .
In the competitive domestic enterprises , private enterprises and state-owned enterprises compared to the clear advantage. Private enterprises are newer businesses, small operational burdens , operating flexibility, rapid development ; compared to the wire and cable industry in state-owned enterprises of the old plant are more burdensome aspects of the overall lack of innovation development , so in the private business competition is often a disadvantage.
2 First, second , third camp competition business analysis
In China's wire and cable industry , is an industry leader in absolute WISDOM usb connector including several well-known multinational companies , as well as the domestic cable industry 's leading companies ; second group is the cable industry in a leading position , but with the leading companies there is a certain gap compared to the enterprise, as well as possession of a certain dominance in certain product areas within the enterprise , and the third group is the lack of other features and competitiveness of enterprises.
The first camp - Foreign : Nexans , Pirelli , Sumitomo, Furukawa ; Domestic: Baosheng , Tebian Luneng .
The second camp - New Far East , on the upper , prosper ; special interest in the field of flexible cables.
The third camp - other companies.
Three main means of competition and strategy analysis
Overall, the domestic cable manufacturers technical quality , production WISDOM optical fiber cable capacity, production scale differ greatly from the situation in the low level of competition , more competitive, the price war has been widespread, and thus lead to a decline in product quality. The face of fierce market competition, the cable industry manufacturers should reduce costs through a variety of ways to control fixed costs , strengthen the development of new technologies , the wire and cable industry, strong technical force, product quality and good business will be in good position to compete in the future .
From a variety of factors currently affecting the competitiveness of wire and cable business perspective, quality and technology, marketing , raw materials, internal management is the most important factor in determining the competitiveness of enterprises .
( 1 ) Quality and Technology

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.

The difference with the ordinary power hdmi cable wires and the introduction Description
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 WISDOM fiber optic cable in the sealed configuration of the sheath. An outer protective cover 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 lead wire electrical appliances ﹑ ﹑ ﹑ aviation conductor wires and WISDOM utp cable 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 WISDOM hdmi wall plate has a 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.

mini hdmi cable overvoltage protection measures Code
In order to achieve PCB terminals overvoltage protection and reliable, take appropriate precautions to protect electrical equipment as well as the reasons for their own protection safe operation must be generated against over-voltage, duration, magnitude range. A comprehensive set WISDOM fiber optic cable of protection must have the following three elements are indispensable one. The basic principles of prevention a) comprehensive protection: protection system to consider various possible overvoltage. Rather than for a particular condition. If the system is relatively MOA only limit over-voltage, over-voltage while the white is powerless. 2) Insulation Coordination Reliability: over-voltage protection is designed to protect the safety of equipment insulation, so the argument must be designed to protect the device and insulation withstand capability of the equipment reasonably match. 3) protection of the security of the device itself: Under the protection of WISDOM VGA CABLE electrical equipment can reliably premise must be able to protect the safe operation of the device itself, otherwise, not only can not protect equipment insulation, but cause system accidents.
2. External over-voltage direct lightning and lightning protection for over voltage, current domestic adoption of more lightning network, the lightning rod for protection; For lightning invasion wave overvoltage, mainly because of its manifestations is relatively over-voltage, commonly used WISDOM RAC CABLE to protect MOA .

China wire mini hdmi cable industry in a "sub-healthy" state
China wire and cable industry, while having a leading worldwide production capacity, but there is a more serious product structure is irrational enterprise mainly produces low-value low-voltage wire and cable, and high-pressure, high pressure, such as high-end wire and cable products WISDOM fiber optic cable are dependent on imports . Industry insiders believe that, at present only 30% of China's wire and cable varieties can reach the international market and can compete acceptable level of 70% of the wire and cable product varieties urgent need to improve the level and quality.
Downscale common wire and cable across markets, so competition is more intense, affected the quality issue is China's wire and cable industry persistent pain. Prices of raw materials in the wire and cable industry WISDOM VGA CABLE accounted for about 70% -80% of the cost, so the pros and cons of raw materials greatly affects the quality of wire and cable products, some SMEs in order to save costs, so the raw material to make a fuss , shoddy quality of their products can be imagined. According to statistics departments and industry associations, the presence of poor quality cable huge threat to the safety of construction projects, the current fire accidents occurred in the country, two-thirds of cable quality problems associated with the loss immeasurable.
With China's high-pressure, high voltage power grid construction investment growing increase, but the vast majority of China's wire WISDOM Displayport CABLE and cable business is difficult to produce the products required by the market, which has become a major challenge facing the wire and cable industry. The stamina nowadays sustained and healthy development of China's wire and cable insufficient technical force dispersed, low-tech, large-scale enterprises is not high proportion of market share, product quality problematic, international competitiveness, innovation ability is relatively weak. China wire and cable industry is currently in a "sub-healthy" state, take a scientific adjustment and integration is imperative.
