Theoretically , it is possible to accelerate water move from outside of cable to inside and therefore to accelerate the cross - linking reaction of silane - g - pe by gradient force of electric field when electric pre - stress is applied in the process of warm water cross - linking of silane - g - pe cable 由理論分析得知,在硅烷交聯(lián)聚乙烯電纜的溫水交聯(lián)過程中施加預(yù)電應(yīng)力,通過電場梯度力來加速水由外向里的擴散遷移進而加速交聯(lián)反應(yīng)速度是可能的。
