We are faced with a situation where the sheathing on cables on shipboard (topside) equipment are cracking at high stress points (at bends and clamps). The cable outer sheathing is polychloroprene (neoprene) per the drawing. Then it is coated with some type of preservative. (I don't know what: - MIL-P-11520). In service they are coated by hand with silicone once a month after the equipment is hosed down. Silicone is applied by wiping it on the cable.
However, we are still experiencing the cracking on many of the cables. The required life time is about ten years for these cables as that is the overhaul period where the cables are replaced.
Any suggestions or personal experiences as to what I can do to extend the lilfe of the cables and avoid the cracking problem would be greatly appreciated.
