梅花管、英文Plumtube。是一種梅花狀的通信管材，又稱梅花管和蜂窩管，剛度好、它主要用于移動(dòng)、鐵通、聯(lián)通、網(wǎng)通、廣電等通信電纜護(hù)套管。梅花管是以pvc粒子為主要材料加上其他配方經(jīng)過(guò)獨(dú)特的模具而形成的一種梅花狀的通信管材，又稱梅花管和蜂窩管，此種管材內(nèi)壁光滑，直接可穿光纜，可節(jié)省工時(shí)，其結(jié)構(gòu)合理，使用價(jià)值高，壽命長(zhǎng)。它主要用于移動(dòng)、鐵通、聯(lián)通、網(wǎng)通、廣電等通信電纜護(hù)套管。梅花管采用多孔一體結(jié)構(gòu)，剛度好，受力均勻。產(chǎn)品內(nèi)壁摩擦系數(shù)小，穿纜輕快，施工簡(jiǎn)便易行。具有多個(gè)孔位，可預(yù)留管孔，提高通信孔位利用率。接頭采用套接結(jié)構(gòu)。毋需任何工具即可完成管子之間連接，便于施工和維護(hù)。</p><div
