二、DQM防爆電纜夾緊密封接頭性能特點(diǎn)
夾緊電纜,以防拔脫,外管螺紋接頭與螺紋壓帽之間設(shè)一密封膠圈,起到夾緊電纜作用,對于鎧裝電纜又起到接地作用。
Clamping cable to avoid being pulled out A sealing rubber ring is set between outer thread joint and thread press cap. Three metal calws are set in the small end of sealing rubber ring. They will shrink to ward centerwith the rubber ring to clamp the cable and ground the armored cable.
