FLEXIBLE CABLES
The simplest cable is a solid wire with a plastic sheath. It can bend and retains this bending – if you don’t do it too often, because otherwise the wire breaks. Simple cables like these are used in house installations. Once installed, the cable remains in place for decades untouched. Solid wires like these aren’t suitable for many other applications where cables need to be flexible and elastic. Here, the conductors in the cores are made up of strands, fine wire bundles that can be bent millions of times, depending on the design, without breaking and losing their current or data transmission properties.
