Cable tray 300 * 100 according to the specification can accommodate how many cables
Proposed no more than 30% of the total cross-sectional area of the cable / cable cross-section of the total cross-sectional area. Cable bridge is divided into trough, tray and ladder-type, mesh and other structures, by the bracket, arm and installation accessories and other components. The inner frame of the building can be set up independently or attached to various structures and corridors. It should be characterized by simple structure, beautiful appearance, flexible configuration and convenient maintenance. All parts are galvanized. , Installed in the building outside the bridge
(DigitalTVPCIcard), inserted in the PCI seat, followed by a signal interface to the antenna, but also with video transcription function. There are also external.
Coaxial cable Fine cable laying should not be twisted; b. The radius of the cable should be greater than 20cm; c. Installed in the cable on the work of the distance between the work sites should be greater than 05 meters; d. The installation of the cable connector should be reliable, and should prevent the signal from short circuit; Fine cable alignment should be in the cable slot to prevent damage to the cable; f. When laying the cable, do not pull hard to prevent the pull off; A section of the cable should be less than 183 meters, 183 meters within the two sections of cable can generally be used "T" head lengthened; h. Both ends must be installed terminal device, each at least one terminal to ground; i. Coaxial cable can not be installed in the outdoor, installed in the outdoor part of the casing should be installed. Twisted pair Twisted pair in the corridor and indoor alignment should be in the cable slot, should be straight alignment; b. Workstation to hub twisted pair of the longest distance of 100 meters, more than 100 meters available twisted pair connector to lengthen; c. Twisted wire in the machine room to be bundled into the line line, the alignment must have some rules, not chaos; d. Twisted pair at both ends to indicate the number, easy to understand the node and Hub interface corresponding relationship; e. Twisted pair should be firmly inserted into the hub and workstation network card; f. When the node is not used, do not unplug the twisted pair, it does not affect other nodes work; Twisted pair is generally not installed in the outdoors, a small part of the installation in the outdoors, installed in the outdoor part of the casing should be installed; h. Use eight core twisted pair, install their own joints, the eight lines should be installed, do not just install four lines, cut the other four lines.
Computer city to sell, what the equipment is really forgotten, you go to that description they know, the equivalent of a signal adapter, the cable cable connected to the device, the device transferred to the computer monitor, There is a need for a speaker can see the electric Fan Fan test both Yao Huan surprised only Leaping, and do not need chassis
