Embodiment 1
[0031] refer to Figure 1-5 , a moisture-proof cable for underground wiring, comprising an inner core layer 1, and the outside of the inner core layer 1 is sequentially wrapped with an inner sheath layer 2, an armor layer 3, a buffer layer 4, a moisture absorption layer 5 and an outer sheath layer from the inside to the outside. 6; the inner core layer 1 includes a wrapping tape 11 and three cable cores 12 arranged in an array inside the wrapping tape 11, and the gap between the wrapping tape 11 and the cable core 12 is filled with waterproof grease 13 , the waterproof ointment 13 has good hydrophobicity, preventing moisture from further infiltrating into the inside of the cable body; the buffer layer 4 includes an outer rubber sleeve 42, an inner rubber sleeve 41, and arranged between the outer rubber sleeve 42 and the inner rubber sleeve 41. In the buffer ring 43 , the outer surface of the inner rubber sleeve 41 has a plurality of first grooves 411 equidistantly spaced, and ...
Embodiment 2
[0033] like Figure 1-5 As shown, this embodiment is basically the same as Embodiment 1. Preferably, the cable core 12 includes a central reinforcing core 121, a plurality of copper wire conductors 122 wound on the outer surface of the central reinforcing core 121 and stranded, and a plurality of copper wire conductors 122 wrapped around the copper wire The insulating sleeve 123 outside the conductor 122, the gap between the insulating sleeve 123 and the copper wire conductor 122 is filled with glass fiber, and the glass fiber is filled in the gap, which can prevent the copper wire conductor 122 in the insulating sleeve 123 from loosening. 121 enhances the tensile strength of the copper wire conductor 122 and reduces the possibility of the copper wire conductor 122 breaking.
Embodiment 3
[0035] like Figure 1-5 As shown, this embodiment is basically the same as Embodiment 1. Preferably, the insulating sleeve 123 is made of polyethylene, which has good insulation, low temperature resistance and corrosion resistance. Oil-impregnated paper, polyvinyl chloride, polyethylene, cross-linked polyethylene, rubber and other materials can be used, and the central reinforcing core 121 is made of soft rubber.
