Description
Application of twisted couple
The SFTP cable, and also FTP and UTP are widespread today. Wires use for creation of the data transmission networks mounted according to the Russian and international standards: standards TIA/EIA 568-A, ISO/IEC 11801, EN 50173. In documents such parameters as the maximum length of system of cables, other strictly designated sizes are specified.
Characteristics of wires are also reflected in standards. Are the most important:
own and transitional attenuation,
capacity,
level of returnable losses,
full resistance, etc.
Twisted UTP, FTP, SFTP steam shows a certain speed of a transmission of information. Generally there are 5 categories of wires with own parameters and requirements. Features of cables need to be considered upon purchase of products for internal and external use.
Design features of twisted couples
Copper vein. Twisted couple represents several cables from copper conductors with a diameter from 0,575 to 0,48 millimeters. The wire (UTP cable) applied to production of twisted cords has to be bending. For its production use a multiwire vein of bigger section as value of own attenuation at it is higher.
Screen. Wires subdivide on screened and unscreened which have no protection against hindrances, for example, the utp cable 6 categories.
The screened cord is designated by SFTP. Twisted couple differs in higher resistance to noise, is characterized by the improved parameters of transitional attenuation. However laying of screened twisted wires more labor-consuming: it is necessary to use special sockets and schemes of grounding.
Russia uses unscreened couples more often. The cord of UTP is used at installation of networks of different function, for example,
telephone or computer. Wires of UTP 2 and 6 of category, the utp 5e cable (2 couples) are the most widespread, the FTP cables protected by aluminum foil are also widespread. The insulating tape is applied to the increased protection. Twisted SFTP steam it is in addition screened a copper braid or at once two materials. Shielding the general or on the twisted cables. The drainage conductor representing the thin not isolated copper wire protects the screen from mechanical damages.
Cover material. Twisted couple is isolated by different materials. The most widespread is the plasticized polyvinylchloride. Wires with PVC cover apply to use in rooms. Material differs in the low cost, good resistance to ignition. More reliable protection against fire is provided by a cover from the self-fading polyethylene. At installation in zones with the increased danger of ignition use halogen-free compounds which give small smoke. Because of it the price of wires changes, the mechanical UTP parameters and other cables decrease.
Color of a cover, as a rule, gray, but also other shades are possible. If twisted couple is made for external application, then it is covered with black isolation which possesses bigger protection against an ultraviolet and the increased humidity.
