System for preventing undue bending of cables

摘要

A cable system is disclosed including a central cable; an inner membrane having a higher minimum bend radius than the central cable and surrounding the cable, thereby forming an inner chamber around the central cable, the inner chamber containing a gas or at least one chemical; and an outer membrane surrounding the inner membrane and forming an outer chamber around the inner chamber, the outer chamber comprising a gas or at least one chemical. When the minimum bend radius of the inner membrane is exceeded, the inner membrane fractures or breaks, and the gas or at least one chemical from the inner chamber enters the outer chamber to create a chemiluminescence reaction, color, or smell.

1. A cable system, comprising:
a central cable; an inner membrane having a higher minimum bend radius than the central cable and surrounding the central cable, thereby creating an inner chamber, the inner chamber containing a gas or at least one chemical; an outer membrane surrounding the inner membrane and creating an outer chamber, the outer chamber containing a gas or at least one chemical; and at least one pair of separating walls that isolate at least one section of the inner chamber and at least one section of the outer chamber surrounding the central cable, wherein the at least one pair of separating walls comprise a double-walled section between which the inner and outer chambers are free of any reactive gases or chemicals, and wherein when the minimum bend radius of the inner membrane is exceeded, the inner membrane fractures or breaks, and the gas or at least one chemical in the inner chamber enters the outer chamber to create a chemiluminescence reaction, a color, or a smell.
