As the term makes it obvious, multicore cables are cables with multiple cores. It is important to note here that it depends on the type of cable. A cable is known as a multicore cable only if the number of cores inside exceeds the usual construction. For instance, a mains cable carrying its four cores is not unusual and hence, cannot be called multicore.
Even a cable with 12 cores will not be called a multicore if the usual design features 12 cores. But cable with four cores becomes multicore if the usual design carries only two. The cores of a multicore cable usually have different functions. These could include power transfer, AV and data transmission — all in one cable. Since the idea is to execute multiple functions, the cable will split into these various ends, each carrying out the function assigned to it.
Where do we use multicore cables?
Most of us are familiar with these cables that connect out TV sets to appliances like a camera, a video or a set-top box. The different cores are required to carry video, audio and other transmission from the implement to the TV. The multicore cable has a wide applicability and can be found in a wide range of industries.
Multicore cables are used in places where we have limited space or where we want to combine multiple functions for convenience. Multicore cables found with medical equipment often fit the first criteria, while those attached to entertainment unit fit the second criteria. Without a multicore cable, it would be simply too tiresome to attach five different cables between the same two units!
How to select multicore cables?
A number of electronic equipment needs multicore cables these days, especially if it is dealing with multiple mediums at the same time, for instance, equipment that deals with data as well as AV transfer. The quality of the cable will ultimately decide the quality of the equipment’s performance. Hence, it is important that we pay attention to the quality and Wires and Cables Manufacturers before selecting a manufacturer and supplier of the cable:
Number of cores:
Since the main purpose of a multicore cable is to execute different functions, we have to first decide the functions that the cable will execute. We need to clearly define the functions and then ask the manufacturer to combine these.
Multicore cables are sully used as instrumentation cables, tasked with carrying AV signals or for data transmission. This requires minimal disturbance from outside factors. This means that like instrumentation cables, the multicore cable also requires extremely effective insulation. Without this, we will have signal disruption and extremely poor performance.
Type of multicore cable:
Again, this depends on the functioning. There are different types of multicore cables for different purposes. The cable could be distinguished according to sheath type, the thinness of the core and so on.
Like power cables, multicore cables are used in diverse terrains, from underwater to rough surfaces. This will decide the corrosion-resistance and the ability to bear wear and tear.
A multicore cable can be flat, twisted, quad or triple constructed. The construction has direct impact on its performance. The selection of the type will depend on the functioning of our electronic equipment, since each construction has its own pros and cons.
Pick a manufacturer who can give you a choice of insulating material. This is because even though you have decided on an insulating material, you can have the space to change your mind. After all, you may have to change the design according to performance or you may want to diversify and require a different material.
This is often the most important criteria in multicore cable manufacturers. Since each cable’s functioning is unique and designed to support the electrical implements we are working with, customization is important. By specifically tailoring our design, we are most likely to get the perfect match.
Although multicore cables are usually flexible by their very nature, you may need to check if you require extra flexibility.
Most multicore cable manufacturers will automatically include colour coding.
This is because of two reasons. Firstly, these cables carry high voltage and the colour coding acts as a warning. Secondly, colour coding is essentially in distinguishing the different functions of the split heads in the cable. However, be sure to check that the right colours are used at the design stage.
