高壓接地線銅線壽命多久？

高壓接地線銅(tong)(tong)(tong)線目前(qian)市場有(you)黃(huang)(huang)銅(tong)(tong)(tong)、紫(zi)銅(tong)(tong)(tong)和(he)無(wu)(wu)氧(yang)銅(tong)(tong)(tong)。黃(huang)(huang)銅(tong)(tong)(tong)是60%銅(tong)(tong)(tong)，40%鋅(xin)。紫(zi)銅(tong)(tong)(tong)又稱紅銅(tong)(tong)(tong)，含銅(tong)(tong)(tong)量99%以上。無(wu)(wu)氧(yang)銅(tong)(tong)(tong)是紫(zi)銅(tong)(tong)(tong)基(ji)礎上進行無(wu)(wu)氧(yang)化加工(gong)，銅(tong)(tong)(tong)表面不易氧(yang)化，電阻(zu)更小。三(san)種產品無(wu)(wu)氧(yang)銅(tong)(tong)(tong)導(dao)電性好(hao)壽命長，電阻(zu)低(di)。紫(zi)銅(tong)(tong)(tong)導(dao)電性好(hao)壽命長。

高壓接地棒的材質
高壓接地棒桿體采用玻璃鋼纖維，接地棒頭為鋁鑄件合金。一般接地棒頭有無堿玻璃纖維和有堿玻璃纖維，其中無堿玻璃纖維更結實。
高壓接地線銅線規格選用知識
1、接地線分為以下幾種：
（1）平口螺旋式高壓接地線
（2）雙簧掛鉤式高壓接地線
（3）單簧掛鉤式高壓接地線
（4）手握式高壓接地線
（5）圓口螺旋壓緊式（猴頭式）高壓接地線
2、接地軟銅線有分相式和組合式。
3、接地端選用接地夾或接地針
4、高壓接地線銅線規格選擇
