Self-supporting railway digital signal cable

Abstract

This invention relates to a self-support railway digital signal cable, which includes cable core, insulating wrapping strip that covers the cable core, jacket cover that outside the insulating wrapping strip, wherein the cable core includes the multi-groups signal wire, the jacket cover felts with the gallus, and the gallus is fixed with the steel hank. When installing span, fixing the two ends of the steel hank directly on the electrical pole, then the cable is installed completely, this installation is shortcut and convenient, which can be used in various environments without steel hank and cable pothook, especially to the slope, bridge, riverway, gorge, highway and so on.

Description

technical field

[0001] The invention relates to a railway digital signal cable. Background technique

[0002] Existing railway digital signal cables usually include a cable core, an insulating tape wrapped outside the cable core, and an outer sheath layer located outside the insulating tape. The cable core usually includes multiple sets of signal lines, and multiple sets of signal lines can be set as required It is an inner shielded four-wire group, an unshielded four-wire group or a combination of two signal lines. At present, the main installation methods of railway digital signal cables are direct burial, pipeline and suspension. Among them, the suspension method needs to first install a steel strand between two poles, and then place it at a certain distance on the steel strand. Several cable hooks are used to hang the installed railway digital signal cables, but in actual construction, special construction environments will be encountered, such...
