2.MPP電纜(lan)保護管可以承受高(gao)壓(ya)電力線纜(lan)在(zai)運行或(huo)過載時產(chan)生(sheng)的(de)局部高(gao)溫(wen)。
3.由于埋深(shen)較深(shen)，MPP電纜保護管可以承受很(hen)大的土壓而不(bu)會產生明顯的形(xing)變。
4.MPP電纜保護管能(neng)夠(gou)在水(shui)平定向鉆進等(deng)非(fei)開(kai)挖工程中承受較(jiao)大(da)的拉伸力和彎曲力。
5.在管材的(de)軸向上具有相當的(de)柔(rou)韌性和(he)可(ke)彎(wan)曲(qu)性。
6.管(guan)材(cai)具有(you)良好的低溫(wen)抗沖擊性(xing)能。
