Webb signal control cables are multi-conductor cables used in automation and instrumentation applications. They are designed to be flexible to enable hassle-free routing and cabling at any location. The inner structure consists of electrolytic stranded copper conductors insulated in a polypropylene compound making the cable fire resistant and flexible. These are then wrapped by an aluminium tape surrounded by tinned copper braiding for increased protection and strength. The cable is further covered with a PVC sheath.
