Electro-Mechanical Cables are designed to fulfill a number of different functions in a single cable. Generally they are used in dynamic applications with wear from tension- tension fatigue and often cycling over sheaves.
TTI is experienced in the design of electro-mechanical cables, which have to be as small as possible in diameter and at the same time robust in arduous applications. These competing needs mean that, unlike with most other cables, there are no national or international standards governing the sizes of these cables or their components. Small differences in design such as the use of copper or copper - cadmium for the conductors or the degree of torque balance, make profound differences to the cable's lifetime. Each design has to take into account the precise conditions of use.
