Embodiment Construction
[0020] The present invention will be further described below in conjunction with accompanying drawing.
[0021] see figure 1 , figure 2 with image 3 , a rubber mold for making factory joints of submarine power cables, comprising a semi-cylindrical upper mold 3 and a lower mold 4 made of hydrogenated nitrile rubber; the upper mold and the lower mold are combined to form a cable insulation restoration area 2; The diameter of the middle part of the insulation restoration area is larger than the diameter of the two ends, and the diameter of the two ends is slightly larger than the diameter of the cable; the top of the upper mold is provided with an injection hole 1 along the radial direction.
[0022] see Figure 4 , a kind of method for making submarine power cable factory joint of the present invention, its steps are as follows:
[0023] The first step is to install the rubber mold: the upper mold 3 and the lower mold 4 of the rubber mold made of hydrogenated nitrile rubbe...
