Abstract
The invention discloses a cross linked polyethylene insulating refractory power cable with rated voltage of 110kv. The cross linked polyethylene insulating refractory power cable comprises a conductor, a cross linked polyethylene insulation layer and an outer jacket, wherein the conductor is arranged at the center inside the cable, a conductor shielding layer wraps the conductor, an insulation shielding layer is arranged outside the conductor shielding layer, a cross linked polyethylene insulation layer is arranged between the insulation shielding layer and the conductor shielding layer, the insulation shielding layer is formed by sequentially and tightly extruding a longitudinal water-blocking buffer layer and a corrugated aluminum sheath from outside to inside, the outer jacket coats the outer surface of the corrugated aluminum sheath, and a high fire-retardant oxygen-barrier layer is arranged between the corrugated aluminum sheath and the longitudinal water-blocking buffer layer. The cable has the advantages of no halogen, no generation of harmful gas and corrosive gas and the like, smoke quantity is low during combustion of the cable, heavy metal such as lead is not included, and soil contamination is prevented.
Description
Technical field
The present invention relates to field of cables, relate in particular 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 is in cable, to have used a large amount of combustible materials and when burning to 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 during 80% personnel death because sucked toxic gas institute extremely, a large amount of smog that produce while simultaneously burning are also unfavorable for personnel's evacuation and fire-fighting and rescue.
Summary of the invention
In order to overcome the defect of above-mentioned prior art, the object of this invention is to provide the crosslinked polyetylene insulated fireproof power cable of a kind of rated voltage 110kv.
The present invention takes 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, described conductor is arranged at cable inside center position; Described conductor is outward to be formed by one deck conductor shield parcel; Described conductor shield is outside equipped with one deck insulation screen; Between described insulation screen and conductor shield, be provided with the crosslinked polyetylene insulated layer of one deck; Described insulation screen ecto-entad is closely to be extruded and form by longitudinal water-blocking resilient coating and corrugated aluminum sheath 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 to be made by LSOH anti-flaming material; The material of described oversheath is polyvinyl chloride, and average thickness is not less than 5mm; Described cable conductor is to be formed by aluminium or copper conductor strand system; Described high flame retardant oxygen barrier layer adopts ceramic silastic material wrapped or extrude and form.
The present invention has following beneficial effect in sum: cable of the present invention has and do not contain halogen, can not produce the advantages such as pernicious gas and corrosive gas, and during burning, the amount of being fuming is few, do not contain plumbous grade for heavy metal, contaminated soil not, thermal endurance class is higher than common PVC electric wire, described oversheath adopts LSOH anti-flaming sheath material, and cable is had outside higher fire-resistance property, possesses the environment-friendly type characteristic of LSOH anti-flaming simultaneously.
Accompanying drawing explanation
Fig. 1 is cross-sectional structure schematic diagram of the present invention;
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, described conductor 1 is arranged at cable inside center position; Described conductor 1 is outer is to be formed by one deck conductor shield 2 parcels; Described conductor shield 2 is outside equipped with one deck insulation screen 4; Between described insulation screen 4 and conductor shield 2, be provided with the crosslinked polyetylene insulated layer 3 of one deck; Described insulation screen 4 ecto-entads are closely to be extruded and form by longitudinal water-blocking resilient coating 5 and corrugated aluminum sheath 6 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 using this device, described cable jacket 7 adopts the material of low smoke and zero halogen to make, and does not contain the harmful substances such as halogen, when it burns, can not cause casualties because of discharging pernicious gas, has the excellent feature of environmental protection; The inner high flame retardant oxygen barrier layer arranging 8 of described cable adopts ceramic silastic 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 guarantee cable normally operation within a certain period of time, and can enter by blocking oxygen, prevent the further burning of cable.
The above is the embodiment of the present invention, and the equivalence of doing according to structure, feature and principle described in the present patent application scope therefore all changes or modifies, and is included in patent claim of the present invention.
