Abstract
The utility model discloses the crosslinked polyetylene insulated fireproof power cable of a kind of rated voltage 110kV, it comprises conductor, crosslinked polyetylene insulated layer and oversheath.Described conductor is arranged at cable inner hub location; Wrapped up by one deck conductor shield forming outside described conductor; Described conductor shield is outside equipped with one deck insulation screen; The crosslinked polyetylene insulated layer of one deck is provided with between described insulation screen and conductor shield; Described insulation screen is closely extruded by longitudinal water-blocking resilient coating and corrugated aluminum sheath to form from inside to outside successively; Described oversheath is coated on the outer surface of corrugated aluminum sheath; One deck high flame retardant oxygen barrier layer is set between described corrugated aluminum sheath and longitudinal water-blocking resilient coating.The utility model cable has not containing halogen, can not produce the advantage such as pernicious gas and corrosive gas, and during burning, the amount of being fuming is few, does not wait heavy metal, not contaminated soil containing plumbous.
Description
Technical field
The utility model relates to field of cables, particularly relates to the crosslinked polyetylene insulated fireproof power cable of a kind of rated voltage 110kV.
Background technology
In recent years, in public place fire, casualties happens occasionally.Main cause be employ in cable a large amount of combustible materials and burning time produce a large amount of smog and poisonous gas institute extremely, because China is populous, public place density of personnel is large, in public places in fire 80% personnel death time because sucked toxic gas institute extremely, during burning, a large amount of smog of producing also are unfavorable for evacuation and the fire-fighting and rescue of personnel simultaneously.
Summary of the invention
In order to overcome the defect of above-mentioned prior art, the purpose of this utility model is to provide the crosslinked polyetylene insulated fireproof power cable of a kind of rated voltage 110kV.
The utility model is taked following technical scheme to realize: the crosslinked polyetylene insulated fireproof power cable of a kind of rated voltage 110kV, and it comprises conductor, crosslinked polyetylene insulated layer and oversheath, and described conductor is arranged at cable inner hub location; Wrapped up by one deck conductor shield forming outside described conductor; Described conductor shield is outside equipped with one deck insulation screen; The crosslinked polyetylene insulated layer of one deck is provided with between described insulation screen and conductor shield; Described insulation screen is closely extruded by longitudinal water-blocking resilient coating and corrugated aluminum sheath to form from inside to outside successively; Described oversheath is coated on the outer surface of corrugated aluminum sheath; One deck high flame retardant oxygen barrier layer is set between described corrugated aluminum sheath and longitudinal water-blocking resilient coating; Described oversheath is made up of LSOH anti-flaming material; The material of described oversheath is polyvinyl chloride, and average thickness is not less than 5mm; Described cable conductor is formed by aluminium or copper conductor system of twisting; Described high flame retardant oxygen barrier layer adopts Ceramic silicon rubber material wrapped or extrude and form.
The utility model has following beneficial effect in sum: the utility model cable has not containing halogen, can not produce the advantage such as pernicious gas and corrosive gas, and the amount of being fuming is few during burning, heavy metal is not waited containing plumbous, not contaminated soil, thermal endurance class is higher than common PVC cable, described oversheath adopts LSOH anti-flaming sheath material, makes cable have outside higher fire-resistance property, possesses the environment-friendly type characteristic of LSOH anti-flaming simultaneously.
Accompanying drawing explanation
Fig. 1 is the utility model cross-sectional structure schematic diagram;
Wherein: 1, conductor; 2, conductor shield; 3, crosslinked polyetylene insulated layer; 4, insulation screen; 5, longitudinal water-blocking resilient coating; 6, corrugated aluminum sheath; 7, oversheath; 8, high flame retardant oxygen barrier layer.
Embodiment
As shown in Figure 1, the crosslinked polyetylene insulated fireproof power cable of a kind of rated voltage 110kV, it comprises conductor 1, crosslinked polyetylene insulated layer 3 and oversheath 7, and described conductor 1 is arranged at cable inner hub location; Wrapped up by one deck conductor shield 2 forming outside described conductor 1; Described conductor shield 2 is outside equipped with one deck insulation screen 4; The crosslinked polyetylene insulated layer 3 of one deck is provided with between described insulation screen 4 and conductor shield 2; Described insulation screen 4 is closely extruded by longitudinal water-blocking resilient coating 5 and corrugated aluminum sheath 6 to form from inside to outside successively; Described oversheath 7 is coated on the outer surface of corrugated aluminum sheath 6; One deck high flame retardant oxygen barrier layer 8 is set between described corrugated aluminum sheath 6 and longitudinal water-blocking resilient coating 5.
When this apparatus is used, described cable jacket 7 adopts the material of low smoke and zero halogen to make, and not containing harmful substances such as halogens, when burned, can not cause casualties, have the excellent feature of environmental protection because of release pernicious gas; The high flame retardant oxygen barrier layer 8 that described cable inside is arranged adopts Ceramic silicon rubber material to make, during breaking out of fire, described high flame retardant oxygen barrier layer 8 forms rapidly the ceramic duricrust that one deck has certain insulation characterisitic, to ensure that cable normally runs within a certain period of time, and can enter by blocking oxygen, prevent the further burning of cable.
The above is the utility model embodiment, therefore all equivalences done according to structure, feature and the principle described in the utility model application range change or modify, and are included in the utility model patent claim.
