实际工作过程中：
在海底依靠水下电动轮9跨在海底电缆两边运行，前端的海底泥沙吸除装置12将填埋电缆的泥沙吹除放在电缆两边，泥沙吸除监控13观看吸除情况，水下电缆表面情况监控11寻找电缆破损位置，当电缆表面破损位置确定在电缆绝缘层修复机构3正下方后，两个电缆取放机构2下降，抓取电缆后上升，将电缆放入电缆绝缘层修复机构3内。
水下电缆表面冲洗装置10开始对电缆表面进行冲洗，水下电缆表面情况监控11观察冲洗情况；当破损处被冲洗干净后，两个电缆取放机构2继续上升，将电缆放在后部半边耐压壳体301和前部半边耐压壳体310中间；三个水下电动推杆309将推动前部半边耐压壳体310向后部半边耐压壳体301移动，要确保电缆被后部半边耐压壳体301和前部半边耐压壳体310夹在中间，当后部半边耐压壳体301和前部半边耐压壳体310进行配合后，两个水下齿条电 动推杆304的齿条向下运动，带动四个配合的锥形螺纹带齿半圆锁紧块305向锥形螺纹外径大的一端转动，将后部半边耐压壳体301和前部半边耐压壳体310夹紧，密封圈和电缆被压紧，保证了密封。
首先水下抽水控制电磁阀302打开，水下抽水装置6通过水下抽水控制电磁阀302将耐压壳体内的水抽干，方便后面密封橡胶更好的粘合电缆破损的表面；然后等水抽干后，水下抽水控制电磁阀302关闭，水下抽水装置6停止工作；水下灌胶控制电磁阀306打开，水下补胶装置5通过水下灌胶控制电磁阀306的控制来对后部半边耐压壳体301和前部半边耐压壳体310内灌胶，当橡胶罐满后，水下灌胶控制电磁阀306关闭，水下补胶装置5停止工作；水下高压空气控制电磁阀307打开，水下高压空气装置4通过水下高压空气控制电磁阀307对后部半边耐压壳体301和前部半边耐压壳体310内充高压空气，防止海水的进入和更好将密封橡胶挤压进电缆的缺损处紧密粘合，等经过一定时间后，水下高压空气控制电磁阀307关闭，水下高压空气装置4停止工作。
两个水下齿条电动推杆304的齿条向上运动，带动四个配合的锥形螺纹带齿半圆锁紧块305向锥形螺纹外径小的一端转动，将后部半边耐压壳体301和前部半边耐压壳体310放松，密封圈和电缆密封失效，当齿条移动一定距离后，四个水下电磁顶针303开始动作，顶针穿过锥形螺纹带齿半圆锁紧块305的孔，固定四个锥形螺纹带齿半圆锁紧块305不再滑动脱落。三个水下电动推杆309开始动作，将后部半边耐压壳体301和前部半边耐压壳体310分开，然后；两个抓取电缆的电缆取放机构2下降，此时水下电缆表面情况监控11观察电缆表面修复情况，如果修补不成功，将重复上述动作，修补成功后，将修补后的电缆放入海底，此时水下电动轮9开始前进，与此同时，海底泥沙填埋装置8将原来吸除的泥沙再次填埋修补后的海底电缆，水下泥沙填埋监控7观察填埋情况，最终完成了电缆绝缘层的整个修复工作。通过该装置可以在海底原位对电缆破损的绝缘层实现快速修复，避免了将海底电缆带到陆地或船上进行复杂的修复。
