Electrical Cable Sheathing

Industrials cables are design in various types of sheathing materials to ensure the protection of the wires in application. Each type of sheathing material is design for a specific purpose. Choosing a cable with insufficient sheathing material can be a waste of money, time and energy. Hence, it is essential to understand the types of wire and the sheathing material before u choose a wire for your application.

Cables and Their Insulations

There are 3 types of insulation that are used when discussing standard or custom cable. They are explained below:

  • Non-metallic Cables:Sheathing material used to produce non-metallic cables are cardboard or weighted paper, which is covered in plastic. These cables are mostly used where the chances of damage are quite insignificant, and they are protected from water and moister. They are used in electrical switches, outlets and other types of building wiring.
  • BX Cable:It is covered in a metallic flexible sheath. A ground wire is not required due to the metal part of sheath. Since the sheath is flexible we are able to use it in compact spaces. For this reason, this type of cable is applicable in basements-areas that contain moister.
  • UF Cables:Also known as underground feed cables are designed with heavy paper and plastic for insulation attributes. As the name refers these cables are applicable in underground areas like subways and branch circuit

By understanding the types of sheathing you will be able to choose the appropriate cable for your application.
