In this post, we will learn the difference between single-core and multi-core cables.
Cables are a very important part of industrial automation. You must know which cable to use and where to use it so that there is no goof-up in the instrument part or electrical part.
There are many types of cables used, but it is important to categorize them based on various sections. Because it is not possible to define every type in a single section.
In this post, we will focus on two types of cables – single core and multi-core. Here, we will see the difference between both of them.
Cables come with conductors and insulators. Conductors are the ones that carry current and insulators are the ones that insulate or protect the conductor from the external environment.
In a single-core cable, as the name defines, only a single conductor or wire is used inside a cable. Basically, it will simply consist of a single wire insulated in an external coating layer.
Because a single conductor is used, it can be used with a large and thick diameter. So, it is said to be more reliable, flexible, and durable.
Consider two power cables of line and neutral. It is a perfect example of a single-core cable where two single-core cables are used. Refer to the below image for understanding.
In a multi-core cable, as the name defines, multiple conductors or wires are used inside a cable. Basically, it will simply consist of multiple wires insulated in an external coating layer.
Because multiple wires are used, there is a limit on its thickness and diameter. Mostly, the generally used ones are two-core, three-core, and four-core ones.
Consider your normal laptop charger. The charger cable has three wires inside it – line, neutral, and earth. It is a perfect example of a multi-core cable where a single cable is used with three wires inside it. Refer to the below image for understanding.
Below are the key points that differences between single-code cable and multi-code cable.
In this way, we understand the difference between single-core cable and multicore cable.
