A shipboard cable-hauling system for large electrical cables

تخمین عمر عایقی کابل های فشار قوی XLPE تحت تنش های حرارتی، الکتریکی و همزمان

The aging of insulating materials can be estimated by an electrical breakdown occurring in electrical components so that the relationship between lifetime, failure probability and reliability of electrical components may be studied using the life models in high voltage cables networks. In last decades with attention to higher features as electrical, thermal, mechanical characteristic, widely cr...

Cable-suspended planar parallel robots with redundant cables: controllers with positive cable tensions

Cable-suspended robots are structurally similar to parallel actuated robots but with the fundamental difference that cables can only pull the end-effector but not push it. From a scientific point of view, this feature makes feedback control of cable-suspended robots lot more challenging than their counterpart parallel-actuated robots. In the case with redundant cables, feedback control laws can...

Actin: A molecular wire, an electrical cable?

Microbes, cables, and an electrical touch.

In nature, highly efficient and diverse consortia of microbes cycle carbon and other elements while generating energy for growth. Driving these reactions are organisms with the ability to extract electrons from the chemical substrates and transfer them to insoluble and soluble electron acceptors. One bacterial group in particular, Geobacter spp., can couple their respiratory metabolism to the r...

A Cable Configuration Technique for the Balance of Current Distribution in Parallel Cables

A cable configuration technique for the balance of current distribution in parallel-connected single-core cables is proposed. Based on the mutual inductance theorem, a closed form solution for the calculation of current distributions in parallel-connected cables is first derived. To compare the performances of different cable configurations, two indices are introduced, one for the power losses ...
