This invention discloses a novel
rodent- and termite-proof ultra-
high voltage cable, comprising a cable body, which, from the inside out, consists of a conductor, an
insulation layer, a filling layer, a wrapping tape, an inner sheath, a steel strip, and an outer sheath; it also includes two protective tubes, each with a storage cavity containing a repellent liquid; a clamp, on which a
sponge and a sealing strip are fixedly mounted, and a connection hole is provided; the protective tubes have a connecting part, and the storage cavity is connected to the connection hole through the connecting part; by adding the repellent liquid into the storage cavity, it is absorbed by the
sponge through the connecting part and the connection hole, giving the connection between the protective tube and the cable body a termite-proof effect; and after the repellent liquid on the
sponge evaporates and sublimates, the
constant force spring pulls on the sliding rod and sliding ring, causing the sliding ring to push the repellent liquid to replenish the sponge, thereby ensuring the
rodent- and termite-proof effect of the cable after connection.
