金陽光電纜廠家提醒現場修補應注意的問題

       在(zai)電(dian)纜的(de)現(xian)(xian)(xian)場(chang)(chang)敷設過(guo)程中電(dian)纜護套外觀(guan)刮傷(shang)破(po)損的(de)征(zheng)象(xiang)是普遍(bian)存在(zai)的(de)，損傷(shang)輕(qing)微(wei)的(de)只傷(shang)及(ji)了護套，如何修補能(neng)保(bao)證質量，而(er)且(qie)修補時間短，又能(neng)保(bao)證質量日益成為(wei)(wei)電(dian)纜消(xiao)耗者普遍(bian)關心(xin)的(de)題目。而(er)且(qie)投入小(xiao)，在(zai)現(xian)(xian)(xian)場(chang)(chang)的(de)惡劣條件下又容易實(shi)現(xian)(xian)(xian)，因此(ci)現(xian)(xian)(xian)場(chang)(chang)護套的(de)修補技術及(ji)質量日益成為(wei)(wei)用戶關心(xin)的(de)題目。
