1、太(tai)陽能(neng)電(dian)熱(re)帶尾端處按45度切(qie)成鈍角，非(fei)標電(dian)熱(re)管(guan)采購，尾端必須用(yong)熱(re)收(shou)縮(suo)管(guan)做好防(fang)水絕緣處理。

2、電(dian)(dian)(dian)熱帶(dai)(dai)電(dian)(dian)(dian)源接線端剪成不等式，電(dian)(dian)(dian)熱帶(dai)(dai)與電(dian)(dian)(dian)源線連接處應牢固，兩(liang)根接線端應用銅套管(guan)分(fen)別固定后套入熱收(shou)縮(suo)管(guan)做防水絕(jue)緣(yuan)處理，再用熱收(shou)縮(suo)管(guan)從電(dian)(dian)(dian)熱帶(dai)(dai)的外(wai)絕(jue)緣(yuan)處到(dao)兩(liang)芯電(dian)(dian)(dian)源線之間做二次絕(jue)緣(yuan)防水處理，以防電(dian)(dian)(dian)熱帶(dai)(dai)的發熱體滲(shen)水，導致電(dian)(dian)(dian)熱帶(dai)(dai)著火。
