Precautions for piping galvanized electric pipe grounding

When the weak current system uses galvanized electric pipes, the grounding device should meet the following requirements:

1 Threaded connection between pipes, the length should not be less than 1/2 of the pipe joint, the thread should be smooth, no defect, and coated with electric compound fat or conductive anti-corrosion grease. After connecting, the thread should be exposed with 2~3 buckles.

2 The tube is connected by a sleeve with a set screw. The screw should be tightened and anti-loose measures should be taken.

3 The connection between the pipe and the box should be made of conductive metal nanoparticles.

4 When there is a PE line in the weak electric tube, each junction box should be connected to the PE line.
