To reach above-mentioned technical purpose, the technical solution of the utility model is:
A kind of crosslinked polyetylene insulated buried cable for airport flight assistant lamp light circuit of water resistant tree, leading including cable center
Body, the conductor set gradually semiconductive conductor shield, the crosslinked polyetylene insulated layer of water resistant tree, semi-conductive insulation shield layer outside
And metal screen layer, conductor, semiconductive conductor shield, the crosslinked polyetylene insulated layer of water resistant tree, semi-conductive insulation shield layer and
Metal screen layer forms insulated wire cores, is tightened outside metal screen layer using intumescent waterstop, in intumescent waterstop outer layer
It is outer to be wrapped up using double-sided aluminum plastic composite band, extrude high density polyethylene (HDPE) sheath again outside double-sided aluminum plastic composite band to form water resistant
Set crosslinked polyetylene insulated buried cable for airport flight assistant lamp light circuit.
The conductor is twisted into the 2nd kind and is twisted using the annealing copper wire of 7 1.04mm presses copper conductor.
The double-sided aluminum plastic composite band with a thickness of 0.23mm.
The semiconductive conductor shield, the crosslinked polyetylene insulated layer of water resistant tree and semi-conductive insulation shield layer use three
Layer co-extrusion is formed.
The metal screen layer is formed using copper strip shielding overlapping is wrapped.
Compared with prior art, the utility model has the beneficial effects that conductor using the 2nd kind it is twisted press, conductor is softer to be mentioned
High cable bend performance；Cable uses three-layer co-extruded technology, and partial discharge quantity is smaller, and insulation mechanical and physical performance is more stable；
Insulation uses water resistant cross-linked polyethylene insulating material, prevents water tree from being formed, and extends cable service life；Integrated water stop layer uses
The double-sided aluminum plastic composite band of 0.23mm thickness is bonded oversheath high density polyethylene (HDPE) protective cover material, can effectively prevent moisture intrusion cable exhausted
Edge layer；Block water, water resistant tree, service life are high and it is at low cost, be very suitable for airfield aid light circuit buried cable.
Detailed description of the invention
FIG. 1 is a schematic structural view of the utility model.
Figure label respectively indicates, 1-conductor, 2-semiconductive conductor shields, and 3-water resistant trees are crosslinked polyetylene insulated
Layer, 4-semi-conductive insulation shield layers, 5-metal screen layers, 6-intumescent waterstops, 7-double-sided aluminum plastic composite bands, 8-is high
Density polyethylene sheath.
Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
Every other embodiment obtained, fall within the protection scope of the utility model.
Referring to Fig. 1, the utility model provides a kind of technical solution:
As shown in Figure 1, a kind of crosslinked polyetylene insulated buried cable for airport flight assistant lamp light circuit of water resistant tree, including cable
The conductor 1 at center, the conductor 1 set gradually the crosslinked polyetylene insulated layer 3 of semiconductive conductor shield 2, water resistant tree, partly lead outside
Be electrically insulated shielded layer 4 and metal screen layer 5, the crosslinked polyetylene insulated layer 3 of conductor 1, semiconductive conductor shield 2, water resistant tree, half
Conductive insulation screen 4 and metal screen layer 5 form insulated wire cores, are pricked outside metal screen layer 5 using intumescent waterstop 6
Tightly, it is wrapped up, is extruded again outside double-sided aluminum plastic composite band 7 highly dense using double-sided aluminum plastic composite band 7 outside 6 outer layer of intumescent waterstop
Degree pe sheath 8 is to form the crosslinked polyetylene insulated buried cable for airport flight assistant lamp light circuit of water resistant tree.
The conductor 1 is twisted into the 2nd kind and is twisted using the annealing copper wire of 7 1.04mm presses copper conductor.
The double-sided aluminum plastic composite band 7 with a thickness of 0.23mm.
The crosslinked polyetylene insulated layer 3 of the semiconductive conductor shield 2, water resistant tree and semi-conductive insulation shield layer 4 are adopted
With three-layer co-extruded formation.
The metal screen layer 5 is formed using copper strip shielding overlapping is wrapped.
Insulating materials use water resistant tree Insulation Material, the mechanism of water resistant tree cable material be in XLPE addition water tree inhibitor or
Achieve the purpose that reduce or eliminate water tree by polymer-modified.Its service life of cable by the processing of water resistant tree is than tradition electricity
Cable has increased significantly, and average life span was up to 40 years.
Cable, as radial resistivity water layer, by longitudinal wrap aluminium-plastic tape and extrudes poly- second using aluminium-plastic tape integrated sheath
Alkene oversheath reaches the purpose that blocks water jointly.Its mechanism that blocks water are as follows: when extruding pe sheath, due to polyethylene melt high temperature and
Pressure effect, the polyethylene film of plastic-aluminum combined belt surface be able to pe sheath inner surface it is be bonded very well, while plastic-aluminum answer
Putting up between crossed belt longitudinal wrap also obtains good bonding, so that completely plugged moisture penetrates into the approach of cable.
Longitudinal water-blocking.Using waterstop wrapped outside copper strip shielding, mechanism is: if sheath rupture encounters water, blocking water
Material expands rapidly, is formed and moisture is prevented longitudinally to invade along cable together " dam ".
The research of cable cover(ing) special material is chosen, to prevent meiofauna such as hare, vole from attacking cable, outside cable
Sheath selects the higher HDPE material of hardness, and the termite-proof repellent agent of addition environmental protection wherein.
While there has been shown and described that the embodiments of the present invention, for the ordinary skill in the art,
It is understood that these embodiments can be carried out with a variety of variations in the case where not departing from the principles of the present invention and spirit, repaired
Change, replacement and variant, the scope of the utility model is defined by the appended claims and the equivalents thereof.
