Every cable we design is bent, stretched, rotated and otherwise tortured as part of our verification process. What we do and how? In the first blog of this two-part mini-series, I outlined why mechanical testing can’t be ignored when it comes to designing high performance cables.
When working with cables in shallow water, relatively less of the cable will be submerged while the rest of it is wound on a drum on the vessel. In deep water applications, where relatively more of it is deployed, water provides a cooling effect for the cable when it is subjected to electrical currents. In contrast, in the shallow water applications, layers of cable are spooled on a drum on the vessel and these layers are unable to benefit from the cooling effect. Eventually, the heat caused by the electric current flowing through the cable builds up.
