How to use -40*4 galvanized steel bar to do grounding electrode?
The combination of conductors or conductors that are buried in the earth so as to connect with the earth is called a ground electrode. The grounding electrode is the electrode which is in full contact with the ground and realizes the connection with the earth. In the electrical engineering, the grounding electrode is made of a plurality of 2.5M long, 45X45mm galvanized steel angles, and is nailed at the bottom of the 800mm deep groove, and then is drawn out with the lead out line.
Take 3 2.5m long 50 galvanized steel bars spaced 5m, buried in the ground 0.6m, and then galvanized flat steel and angle steel welding.
The -40*4 galvanized flat steel is used as the grounding electrode, and the horizontal grounding electrode needs to be welded with the lead wire.
