High performance cable should provide the best in durability, flexibility and shielding!

July 12, 2023

Cable manufacturers are constantly challenged with wider temperature ranges, more shielding functions and higher mechanical durability, as well as characteristics such as bending resistance and chemical resistance required for extremely harsh environments and increasingly complex applications. However, cable failures and system downtime still occur from time to time, why?


Cable Faults Many problems caused by cable faults, especially those operating in extreme and harsh environments, can be avoided if the cables are selected correctly from the outset. People might say that choosing a cable is easy, but is that really the case? Indeed, matching the correct temperature range and relying on a PVC jacket for protection is simple. However, there are far more issues to consider.


Engineers have many details to consider before finalizing a perfectly matched cable. Flex and flex cables require specific flex shields. When the shield is torn and continuity is lost, the choice of standard foil shielding can lead to system failure. The distinction between flexibility and bendability should be kept in mind. It is important that the cables be able to be bent and fitted, the flexible cables are easier to install and also simplifies fault detection in cabinets and cable trays.


When the cable is used to connect to the cabinet, the round cable provides a better seal than the typical spiral cable. Therefore, it is necessary to correctly select the degree of bending after considering the line. In some manufacturing applications, cables will be constantly being bent. Ability to withstand millions of bends is more complicated than flexibility. So, how to choose a curved cable? The first thing to consider is the type of bending, is it uniaxial, twisted, or multi-axial? Each type requires different characteristics of the cable.
