Data cable

With the high-speed development of optical communication technology, the cable network backbone and interoffice trunk line has been widely used optical cable, optical fiber into access network has become an inevitable trend.
But the high cost of optical cable laying, connectors and terminal optical - electrical conversion cost expensive, therefore, for a long time before the packtized popularization, access network user line will continue to give priority to with metal wire. Including all plastic metal cable cable, coaxial cable and data cable. Among them, the data cable is the ideal of broadband access network transmission media, it has low manufacturing cost, simple structure, good scalability, facilitate the advantages of the network upgrades, it is mainly used for building integrated wiring, computer integrated wiring, etc.
Data cable so far, there are two kinds of cable: one is Americas 100Ω cable, mainly for the non-shielded cable; The other is European 150Ω cable, mainly for shielded cable.

International standards generally fall into three categories, four, five, five, six, enhance sexual respectively corresponding to the transmission bandwidth of 16MHZ, 20MHZ, 100MHZ, 100MHZ (support full-duplex transmission), 250MHZ, with seven, eight even now there is no formal definition on the international standard, just of the hype of cabling manufacturer; Levels corresponding to different data cable has the symmetry of the corresponding channel level and, general component is currently CLASS A and CLASS B, CLASS C, CLASS D, CLASS E level, of course and there have been pushed CLASS F grade now. Actually two different areas on different impedance requirement of cable is different based on their structure, generated by the America of 100Ω cable, mainly America so far are not pushing block structure, this is because if the shielding structure can form between the conductor and shield near effect, low frequency parameters, such as change of capacitance and resistance, the other on the shield will have high frequency litter of spin current is generated. But don't block structure, cable, there is no resistance to interference ability and confidentiality is poor, and if you want to do it as more than 300MHZ transmission is difficult, so Europe is implemented block structure, so how to eliminate from the worries of the shield, had to increase through impedance, so Europe is in commonly 150Ω cable. Two structures who good who bad will decide that according to the different application environment, so now the international wiring are generally pay attention to the combination of the two kinds of wiring way. Wide application but it is not shielded structure, and the result of the development of information technology, to follow up the transmission bandwidth requirement, at present more popular is five classes and increase sexual five categories of data cable shielding.

Cable insulation material field in our country

Cable insulation materials, especially high voltage cable insulation materials commonly used in plastics polyethylene, polypropylene, PVC, and other special plastic.
1. PE class cable insulation material
Polyethylenes cable insulation material high insulation resistance, voltage resistance performance is good, especially the dielectric constant and dielectric loss is small, the influence of temperature and frequency is small, and it has good physical and mechanical properties and water resistance, solvent resistance, drug resistance. Related patents on PE class cable insulation materials mainly involved polyethylene cable insulation materials on the flame retardancy, water tree electrical resistance, anti-aging, oxidation and resistance against wear and charred aspect as well as the effect of preparation technology on the improvement.
2. Polypropylene cable insulation material
Polypropylene class cable insulation material density is the smallest and lightest, its heat resistance and mechanical strength is better than that of PE, especially the high frequency characteristics, the modified flame retardant is tasted, can be obtained from foaming.
3. PVC insulated cable material
PVC insulated cable material resistant to high voltage and insulation resistance, flame retardant, oil proof, weather resistance, chemical resistance, corona resistance and water resistance performance, but its dielectric constant and dielectric loss is bigger, cold resistance is poorer, is often used to 1kv and below the wire and cable, semiconduction shielding and all kinds of wire and cable sheath.
4. Other cable material
In addition to the three general plastic formation of the cable insulation materials, fluorine plastic, polystyrene, polyimide and polyamide, polyester and other plastics is also used as cable materials, these materials have a certain feature is also used in some special occasions, such as ptfe, its thermal performance is good, continuous working temperature is 250 ℃, and electrical properties, flame retardancy is better also. But since they don't melt at high temperature, which is unfavorable for processing, and high mechanical strength is not enough, so often as the second polymer and three general plastic copolymerization or blending to improve the properties of the insulated cable materials, through special processing method, a small, separate and high frequency cable insulation materials used for high temperature wire.

In addition, in the field of application for a patent in China is more dispersed, patent quality remains to be improved, there are few enterprises or scientific research institutions formed by a series of interlocking technical patent protection. Anytekabel Co.,Ltd.(www.anytecable.com) the cable has passed CCC, CSA, TUV, CE...Such as certification. At the same time made the patent management system, fully mobilize the employees' innovation enthusiasm.

General Selection Principles of Wire and Cable

Generally pay attention to the choice of wire and cable type, specification (conductor cross section), when you choose wire and cable.
1. The choice of wire and cable model number
Consider the application, installation conditions and security, when you choose wire and cable. For example,
According to different applications, you can select the power cables, overhead insulated cables, control cables, etc.;
Depending on the installation conditions, you can choose the general plastic insulated cables, steel tape armoured cable, steel wire armoured cable, anti-corrosion cable, etc.;
According to the security requirement, you can choose flame-retardant cables, halogen-free flame retardant cable, fire-resistant cable, etc.
2. The choice of wire and cable specifications
Make sure the specifications (conductor cross section) of wire and cable, generally consider the selection condition of fever, voltage loss, economic current density, mechanical strength, etc.
According to experience, because of the large load current of low voltage power line, generally select section according to the heating conditions first, and then calculating the voltage loss and mechanical strength; Low-pressure flare path, because of its higher requirements on voltage level, can select section according to the allows the voltage loss condition first, and then calculating the heating condition and mechanical strength; For high voltage line, select section according to economic current density first, and then calculating the heating conditions and allowed voltage loss; And for high voltage overhead line, should also check its mechanical strength.

The characteristics of flexible cable

High flexible cable is widely used in life and industrial manufacturing, what kind of features makes the high flexible cable so popular?
High flexible cable is on the form is of great importance to PVC outer sheath, the sheath is made of mixed PVC material with high flexible, thus flexibility is excellent. However, because the high flexible cable have this feature, make this cable into the broad industry, mainly used for power transmission and applied to the bending, flexibility requirement high drag chain system.

There are variety of High flexible cable products, can according to the different needs of customers choose to use a different material or different process, expand the use of the cable, the different cable products can meet the demand of different field installation. During the installation process, of course, as a result of the cable of high strength flexibility, not easily broken due to bending of the properties, can greatly reduce the damage rate of staff to the cable, so get the favour of industry installation personnel. Staff need to refer to the instructions on the installation steps, and keep in mind that some daily installation considerations can easily complete the operation, save a lot of time and energy for staff. In addition, high flexible cable products in addition to the characteristics of flexibility, strong resistance to bending, have waterproof and uv protection at the same time, oil resistant, heat resistant, features, so it is suitable to use in the case of poor working conditions.

High flexible cable must be used when produce Drag chain Cable, because the drag chain cable work requires constant bending reciprocating motion, then the cable also need to be relatively active or passive moving, bending motion. Because of the high flexible cable products can ensure normal without load millions of times of movement of the reciprocating bend wire core don't cause fracture, at the same time the characteristics of both high and low temperature resistance makes it can better adapt to the working environment, from all walks of life to so use more widely. In comparison, the other cable to the environment in the process of using or operating various aspects have higher requirements, but this kind of cable is with their own nature advantage, avoid the use of caused many limitations, improve work efficiency for the factory.

There are variety of models of High flexible cables for vendors to choose, and different type side due to the different materials and processes will be focusing on the development of different performance advantages, such as improving insulation, waterproof ability, strengthen the anticorrosive, and so on, but the product has a high standard of resistance to bending damage prevention performance, high quality, easy to operate, the developing of electric power for the factory.
