Model ZH-CGES50--diameter: 50mm--length: 1500, 3000--material: copper tube--impulse current ≤1%--PH value: 7±5% Model ZH-CGES55--diameter: 55mm--length: 1500, 3000--material: copper tube--impulse current ≤1%--PH value: 7±5% The ion grounding system consists of an advanced slow-release ground electrode (with a reversible slow-release filler), an initiator, and a synergistic electrolytic ion filler. The outer surface of the electrode is a copper alloy to ensure the highest conductivity and long service life. It is equipped with two types of fillers inside and outside. The filler is a non-toxic compound and does not pollute the environment.
