Cable BC is a type of Grounding Cable that has no naked alias insulator. So this type of cable consists only of cable cores just called bare cores. The BC cable is often used in the conductor of a conventional type of lightning rod installation or more commonly used in ground systems (earth). This is because using a BC cable with a 50 mm cross section is more economical and also has met the minimum standard of the conductor decrease in lightning protection. It's just as it is known that the BC cable does not have a protective insulator, so it is feared induction lightning stroke and jumping current on the conductor material. So to be safe, the BC cable should be wrapped with a parallel (PVC) pipe.
