Waya ile-aye aabo jẹ o dara fun awọn laini gbigbe, awọn ohun elo agbara ati ohun elo substation, ilẹ kukuru kukuru fun itọju ijade agbara.
Eto pipe ti okun waya ti o ni aabo ni opa iṣiṣẹ ti o ya sọtọ pẹlu agekuru conductive, ilẹ okun okun idẹ rọ pẹlu apofẹlẹfẹlẹ ti o han, PIN ilẹ tabi agekuru ilẹ.
Awọn dimole conductive ti pin si: ilopo orisun omi conductive dimole ati ipin ajija conductive dimole ti a lo lati dimole awọn adaorin, ati ki o alapin ajija conductive dimole ti a lo lati di awọn busbar.
1.Wire clamper pẹlu simẹnti alloy aluminiomu, agbara ti o ga, iṣiṣẹ ti o dara.
2.The šee kukuru-Circuit grounding waya ti wa ni aba ti ni kanfasi apo pẹlu okeere onigi apoti, eyi ti o jẹ rorun lati gbe ati gbigbe.
Awọn nkan ti o nilo akiyesi:
1. Ni akọkọ ṣayẹwo boya ila naa wa laaye ati jẹrisi pe ko si agbara.
2. So ebute ilẹ ni akọkọ ati lẹhinna ebute adaorin.Ọkọọkan ti yiyọ okun waya ilẹ yẹ ki o yiyipada;
3. Awọn ibọwọ idabobo yoo ṣee lo fun apejọ ati sisọ awọn okun waya ilẹ.Ara eniyan ko gbọdọ fi ọwọ kan awọn onirin ilẹ tabi awọn waya ti o ti pari lati ṣe idiwọ itọsẹ inductive.
