The utility model belongs to the technical field of
power cable, especially water -resistant damp -proof
power cable, including the conductor of
copper or
aluminium, the conductor is
copper or
aluminium, the outer layer of conductor is equipped with cross -linked
polyethylene inner
insulation layer, the outer layer of cross -linked
polyethylene inner
insulation layer is covered with semiconductive water -resistant tape wrapping, the outer layer of semiconductive water -resistant tape wrapping is equipped with
ethylene -propylene rubber outer
insulation layer. The utility model, aiming at the drawback of traditional cable under the
damp environment, this cable can effectively block and
discharge moisture through tightly stranded conductor and add water -resistant
powder and water -resistant
yarn, combine multilayer water -resistant,
drainage design, prevent conductor oxidation, insulation layer damage, guarantee
power transmission efficiency and stability, at the same time, the sub -item shielding layer and
aluminium tape shielding layer can shield
electromagnetic interference, the self -repairing
polypropylene of outer sheath layer can
resist harsh environment and self -repair, satisfy 5G
base station construction etc. The high demand of power supply reliability, reduce economic loss and
accident risk.
