With considerable interest in communications, especially with increasing demands for data transmission facilities, railroads are looking with greater intensity at the possibilities of using cable systems. The following article from TELEPHONY describes the basics of cable pressurization and how it can reduce or avoid service interruptions. Some of the advantages of cable pressurization are: 1) Positive internal dry gas pressure prevents moisture or damp air from entering sheath openings, and the resulting dryness helps minimize electrical leaks and noise, prevents cross talk and guards against complete loss of the cable's transmission capabilities. 2) Even in PIC cable, pressurization prevents serious transmission loss and facilitates locating leaks or breaks. 3) Maintenance costs are reduced greatly.
