Differentiated Design And Engineering Application Analysis Of Lightning Protection Copper-clad Grounding Rod System And Conventional Grounding Device

Repeat bonded rod: In a neutral line direct copper bonded system, in order to ensure reliability, in addition to working copper bonded earth rod price at the neutral point of the transformer or generator, necessary copper bonded earthing is also performed elsewhere in the protection line, which is called repeat copper bonded steel.

Protective connection to neutral line: In a 380/220V low-voltage system, since the neutral point is directly copper bonded steel ground rod, the casing of the electrical equipment is usually connected to the neutral line, which is called low-voltage protection connection to the neutral line.
