Power Cable Types: A Guide To Choosing The Right Cable

Best podcast show on cables & wires

A power cable is a form of electrical cable that sends electricity from one medium to another. The types of power cables are composed of a copper or aluminum-made conductor and an insulating coating. The electrical power cable is generally installed in apartments and other structures to maintain the supply of electricity.

This article will help you to know about the common forms of power cables and the ideal place to find them. So, let's start.

• Power cable types

The numerous types of power cables are crucial for varying reasons. Knowing them can help you in understanding each of their functionalities and restrictions. Moreover, if you know the types of power cables, can help you solve a problem if an issue arises. The various power cable types are:

• Low voltage cable:

These types of power cables are suitable for 0.6/1KV electricity modes. Among the many low-voltage wiring types, the PVC-insulated cable is the most common. Aluminum or copper is used as the conductor. These types of power cables are generally for residential and commercial purposes, like electrifying lights, shops, and devices.

• Medium voltage cable:

Justifying its name, medium voltage cables are crafted for systems having a voltage of 600 and 69,000 volts. XLPE is the most popular medium-voltage cable class which means Cross-Linked Polyethylene. This cable form is commonly used in industrial applications. Medium voltage cables are useful for sending electricity to buildings and heavy motors. Armored cables are also used in industrial applications.

• High voltage cable:

Systems with 69,000 volts and above are perfect for high-voltage cables. EPR or Ethylene Propylene Rubber is the commonest type of this power cable. Utility applications like power plants and substations use high-voltage cables. The reason behind this is fewer power outages are caused by this power cable type. Industrial cables are generally high-voltage cables as they consume less electrical current.

• Flexible cable:

This power cable type is shaped for applications where the cable has to be twirled. PVC or polyvinyl chloride is the most common form of flexible cable. Electronic devices like laptops, smartphones, and other gadgets use this cable type. While opting for the metal type you should consider the flexibility requirements. If the application requires an immense amount of flexibility, then you should select a metal with a lower elasticity modulus like copper. On the other hand, if your application needs less flexibility, you can use a metal of higher elasticity modulus like steel.
