Described wire shield layer uniform close is wound in semiconductive and blocks water on buffer strip.Wire shield layer adopts intensity and wire copper of good performance or aluminium and alloy material; it both can meet the pay(useful) load of short circuit current, adopted the frame mode be closely wound around simultaneously, became an entirety; form good armouring protection, avoid cable stressed and damage.
Described semiconductive water blocking layer is wrapped outside wire shield layer, and combine closely with wire shield layer, this layer both can play waterproof effect, wire shield layer can be prevented to be oxidized simultaneously, shield to wire shield layer.
Described inner sheath is extruded in outside semiconductive water blocking layer, and described nylon sheath wire layer is extruded in outside inner sheath, and the material of inner sheath is permeable rate variance and containing the poly material of the high rigidity of moving back deinsectization.
Described nylon sheath wire layer is extruded in outside inner sheath, and its material is nylon 12.
Further, cable insulation core is single or 3, semiconductive water-blocking buffer layer can not only strengthen the blocking water of cable, waterproof ability, and make three-core cable body realize the equipotential of screen due to semiconductor waterstop, metal screen layer is made to become as a whole, its current capacity improves 3 times, ensure that the safe operation of cable, thus improves the useful life of cable.
Anticorrosive coat is equipped with between described nylon sheath wire layer and oversheath; described anticorrosive coat is coating bitumen layer; its anti-corrosion asphalt selected is that the dregs of fat of natural oil decompression distillation obtain because of oxidation; being coated with cylinder by pitch is coated on nylon sheath wire layer; form waterproof outer protective layer, further increase the waterproof effect of cable.
According to the height of electric pressure, described oversheath is the termite-proof restrictive coating of compound protection against rodents, it once extrudes for termite-proof for protection against rodents material and semiconductive material being combined, by changing the ratio of polyolefin jacket material and semiconductive material, make it both reach requirement that the termite-proof object of protection against rodents also has semiconductive performance, not only ensure that its mechanical strength is strengthened, and be provided with the due conductivity in sheath material surface, both saving working hour turn avoid the defect that coated graphite can produce environmental pollution, provided conveniently for operation maintenance personnel detect maintenance.
Compared with prior art, advantage of the present utility model is: (1) adopts the effective protection against rodents of protective layer of high rigidity polyethylene inner sheath and nylon sheath wire double-layer high strength termite-proof, adopting inside and outside bilayer to extrude mode, to protect the duration long, adopt double-deck nonmetal structure simultaneously, avoid the induced voltage loss produced in cable running, portable construction; (2) owing to adopting high strength copper wire shield layer, improve the armouring protection of letting out loading capability and cable body of cable fault electric current; (3) cable internal layer adopts semiconductive water-blocking buffer layer, outerly adopts the polyolefin jacket and asphalt corrosion resistant layer that permeability rate is low, effectively ensures that the blocking water of cable, waterproof ability are strong, long service life.
