style="text-indent:25px">在石化、礦山、煤氣工程等含有易爆危險的場所,通常對電纜提出了“防爆”的要求。由于電火花和熱效應(yīng)是引發(fā)易爆氣體的主要根源,而從系統(tǒng)布線角度考慮,由于電纜是由許多分布電容、電感等分布元件所組成,使其相應(yīng)地成為儲能元件,因此在信號傳輸過程中不可避免地存儲一定的能量。一旦系統(tǒng)出現(xiàn)故障,這些儲能就會以電火花或熱效應(yīng)的形式釋放出來,影響系統(tǒng)的安全性。因此,要求電纜具有低電容和低電感,電纜本身所帶的電荷要少,不易產(chǎn)生電火花;其次,要求電纜具有良好的屏蔽性能,具有優(yōu)良的抗外電磁場干擾及不產(chǎn)生對外的干擾。攀枝花伴熱電纜哪家專業(yè)</p><p
