The anatomy of industrial cables is important to understand its classifications and limitation. Industrial cables undoubtedly are the most abundantly using electrical cables throughout the world. Industrial cables varies according to the requirements of different industries. However, it is important to dig a little deeper towards its specification part by part. Because it helps in identifying the right industrial cable that is needed a particular industry.
Choosing the right industrial cable can really be a painful procedure. However, to make it easier it is important to look for all the nitty-gritty details piece by piece. A typical industrial cable is constructed of five basic components, four of which are primary and one is secondary:
- Primary insulation
Conductors and its types
Starting with conductors; copper is the best one that we had yet. It is best in conductivity, but it might create problems if there is a need to install the cable with tight bends in it. Stranding copper is used to encounter the bending, as it provides the durability and flexibility. Frequently copper conductors are coated to minimize corrosion. Materials most often used to coat the copper are tin or lead, or a combination of the two. Tin is the most common and the least expensive.
Installation place the application for which the industrial cable is selected matters a lot. Industrial cables undergoes different types of insulations. Insulation mainly comes in two different types
- Primary Insulation: This is the actual insulating material that has direct interaction with the conductor. Evidently, it is used to isolate the conductor engraved in a single wire. Polyvinyl chloride (PVC) is often used as the primary insulation because of its cost-effectiveness compared to other materials.
- Secondary Insulation: To encounter environmental challenges the industrial cable still is again insulated. The industrial cable needs to be strong enough to endure intense heat, sometimes even being impervious to weld slag.
Separators and Jackets
Industrial cable uses different separators to facilitate the ease of handling and extruding the conductors from the cable jacket. Cable jacket; sometimes called the “outer jacket,” this material holds all the other components in place and protects them from external threats such as heat, chemicals, splashdown, UV rays, mechanical abrasion, and other trauma.
