    (2)预制式附件所用材料一般为硅橡胶或乙丙橡胶。主要采用几何结构法即应力锥来处理应力集中问题。其主要优点是材料性能优良,安装更简便快捷,无需加热即可安装,弹性好,使得界面性能得到较大改善。是近年来中低压以及高压电缆采用的主要形式。
存在的不足在于对电缆的绝缘层外径尺寸要求高,通常的过盈量在2-5mm(即电缆绝缘外径要大于电缆附件的内孔直径2-5mm),过盈量过小,电缆附件将出现故障;过盈量过大,电缆附件安装非常困难。特别在中间接头上问题突出,安装既不方便,又常常成为故障点。此外价格较贵。    其使用中关键技术问题是:附件的尺寸与待安装的电缆的尺寸配合要符合规定的要求。另外也需采用硅脂润滑界面,以便于安装同时填充界面的气隙。预制附件一般靠自身橡胶弹力可以具有一定密封作用,有时可采用密封胶及弹性夹具增强密封。
