As a further aspect of the present invention: the filling rope layer comprises a filling rope and a water-swelling strip.

As a further aspect of the present invention: the packing rope winding surrounds the setting of meeting water inflation strip, and when few hydrones passed the inflation layer and get into the inlayer, absorbed by meeting water inflation strip, the inflation is more compact with packing rope layer extruded simultaneously, further increases waterproof performance.

Compared with the prior art, the utility model discloses the beneficial effect of following several aspects has:

1. the utility model provides a waterproof insulated cable, the structure sets up ingeniously and arranges rationally, the utility model discloses in during waterproof on current dependence oversheath and waterproof layer carry on waterproof basis, when wading for a long time and take place to permeate, the intraformational water absorption inflation cotton of inflation absorbs the infiltration hydrone and then produces the inflation, has held back hydrone and has penetrated inwards on the one hand, because the pressure of inflation impels the possibility of inlayer cladding tighter simultaneously, thereby further reduced the probability that the hydrone permeates to the inlayer, collocation hydrophobic membrane's isolation, has greatly improved the waterproof performance of cable, and then make cable insulation obtain the guarantee;

2. the utility model further utilizes the extrusion to block the through holes between the rubber blocks to ensure the sealing when the expansion layer expands, and when the expansion layer does not absorb water and expand, the through holes are formed, so that the expansion layer has the self-adjusting function, the material fatigue caused by the expansion caused by heat and contraction caused by cold of the cable is reduced, the effective sealing time is prolonged, and the waterproof service life of the cable is longer;

3. the utility model is further provided with a filling rope to wind and surround the water-swelling strip, when a small part of water molecules pass through the swelling layer and enter the inner layer, the water-swelling strip absorbs the water molecules, and the filling rope layer is extruded more compactly by swelling at the same time, so that the waterproof performance is further improved;

4. the utility model discloses in this cable waterproof performance is outstanding, insulating effectual, and convenient to use is simple, and waterproof life is long.
