Outer surface be provided with insulating layer, and the outer surface for being located at insulating layer is provided with thermal insulation layer, passes through the side on keriotheca
The water that can be will go into inside cable when protective layer occurs damaged in shape cavity filled with water absorption layer, which siphons away, prevents water from causing
The corrosion of internal protection layer, and the steel wire braid by being arranged and buffer layer are realized and play certain anti-extrusion and stretching to cable
Ability, prevent cable because external force squeeze or stretch damage.
Further, what the surface of protective layer was integrated is provided with evenly arranged riser, and the surface of protective layer is provided with
Waterproof layer, waterproof layer select epoxy resin layer, play certain protection to the protective layer of cable surface by the riser of setting and make
With the situation of reduction protective layer breakage.
Further, thermal insulation layer Ceramics fiber or heat insulation foam have preferable more heat effect.
Further, water blocking layer is filled in the gap between the steel wire in steel wire braid, and water blocking layer selects waterproof
Grease, realizing stop to the water entered inside cable by the water blocking layer of setting prevents further to cable inside stream
It is dynamic.
Further, water absorption layer selects water-absorbing resin, and water-absorbing resin has stronger water absorbing capacity, and the suction after water suction
The volume of water-resin can expand, and the water-absorbing resin of expansion, which then squeeze to the water blocking layer in steel wire braid, makes dubbin
Flowing, which is played to block water gap, in the gap of rouge outward avoids having water to enter inside cable again, realizes that preferable waterproof is anti-
Tide effect.
Further, buffer layer selects flame-proof organosilicon glue, and is mixed with glass fibre in flame-proof organosilicon glue, selects
While flame-proof organosilicon glue had not only played buffer function but also play fire-retardant fire retardation.
Compared with prior art, the utility model has the beneficial effects that
(1), can be gone out in protective layer in the utility model by being filled with water absorption layer in the square cavity on keriotheca
The water that will go into inside cable when existing damaged, which siphons away, prevents water from internal protection layer being caused to corrode, the body of the water-absorbing resin after water suction
Product can expand, and the water-absorbing resin of expansion, which then squeeze to the water blocking layer in steel wire braid, makes dubbing outward
Flowing, which is played the role of blocking water gap, in gap avoids having water to enter inside cable again, realizes preferable waterproof and dampproof.
