Background
Traditional submarine cable conductor water blocking adopts a method of wrapping a water blocking tape between each layer of conductors. 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 to fill the gaps of the conductor when the seawater enters the conductor, so that the seawater is prevented from entering the conductor continuously. However, the method has a plurality of defects, firstly, the method can not completely prevent the seawater from entering, but only delay the advancing speed of the seawater, and the time is won for the repair of the submarine cable. However, if the time is too long, the conductor is seriously fed with water, so that a large section of submarine cable is scrapped. Secondly, the water blocking effect of the water blocking tape is greatly reduced along with the increase of the water depth, so that the water blocking tape is not suitable for a deepwater environment as a conductor water blocking material.
Meanwhile, in the use process of the traditional submarine cable, after the water-blocking tape swells in water, obvious influence is not caused on the use of the submarine cable, fault detection is difficult to carry out, fault reaction can only occur on the outer conductor after the water-blocking tape arranged on the outer side swells in a saturated mode, the limit of the water-blocking tape on the inner side from the saturated expansion is quite close, the inner conductor can also fail in extremely fast time, so that time won for the repair of the submarine cable is not much, and the deep sea repair work is difficult to complete before the submarine cable loses functions thoroughly.
