The principle is that water-swelling water-blocking powder is added into the water-blocking tape, when the submarine cable is damaged and seawater enters the conductor, the water-blocking tape swells with water to fill the gap of the conductor, so that the seawater is prevented from continuously entering the conductor along the direction of the conductor. However, the method has many defects, one is that the method cannot completely prevent seawater from entering, only delays the advancing speed of the seawater, and gains time for the emergency repair of the submarine cable. However, if the time is too long, the conductors are seriously watered, and a large section of the submarine cable is scrapped. Secondly, as the water depth increases, the water blocking effect of the water blocking tape is greatly reduced, so that the water blocking tape serving as a conductor water blocking material is not suitable for a deep water environment.
Simultaneously, traditional submarine cable is in the use, the water-blocking tape is after meeting water inflation, can not cause obvious influence to the use of this section submarine cable, and be difficult to carry out fault detection, only after locating the saturated inflation of water-blocking tape in the outside, the conductor in the outside just can the fault reaction, and the water-blocking tape of inboard this moment also has been fairly close apart from the limit of saturated inflation, the inboard conductor also can break down in the very fast time, thereby it is not much to have caused the time of winning to the submarine cable rush repair, be difficult to satisfy and accomplish deep sea rush repair work before the submarine cable thoroughly loses the function.
