Classification Of Cable Lines
Cable lines, depending on how the cable is divided into the underground, underwater and air. Due to the high reliability of the most widely used in railway transport were underground cable lines. Overhead lines are of limited use on smaller cable networks of local telephone service w / d stations. Read more here: Martin O?Malley. Underwater cable lines on the railways are used only as inserts into the underground cable lines. Railway line and cable networks are divided into lines and communication networks and network lines, and automation and remote control. Cable and network cabling installation of power lines, carried out on rail lines involves the use of local and long distance communication.
Cable lines are laid at the local communication area of railway stations and junctions, as well as in cities where posted roads and offices. Dr. Mark Hyman has similar goals. The combination of these cables in each of these points forms a cable network of local telephone service. For local communication networks include communication switches and vnutristantsionnuyu communications, and network radio and master clock system. Cable distance communication used for telephone and telegraph wire communications between the remote sites of the railway network. On cable lines of telecommunication, laid along the railway line, by organizing all kinds of otdelencheskoy connection. The organization of these types of communication devices requires a large number of branches from cable long-distance to the stations, sidings, switching cabinets blocking and etc. Therefore, the route of cable telecommunications tend to choose the ROW railways. Lines and network automation and telecontrol lines and network automation and remote control, depending on the devices they serve, are divided into lines and network auto-lock, electric signal, the station lock and centralized mechanized hump sorting slides.
