Connection is finally completed qualified aerial insulated cable product, and aerial insulated cable is generally used in long-distance sand transport electric power, generally
It is supported using high proping, since cable is in vacant state, tension, creep-resistant property, waterproof and stability
Etc. have higher requirement.
A kind of aluminium core crosslinked polyethylene insulated aerial cable (notification number CN204045265U) of patent includes a kernel
Cable core, multiple outer layer cable cores, crosslinked polyetylene insulated layer, carbon fiber layer, semiconductive water blocking layer and outer jacket, the multiple outer layer
Cable core is looped around the outside of the kernel cable core, the crosslinked polyetylene insulated interlayer be interposed between the kernel cable core with it is the multiple
Between outer layer cable core, the carbon fiber layer, semiconductive water blocking layer and outer jacket are coated on the multiple outer layer cable core from the inside to the outside
Outside.This aluminium core crosslinked polyethylene insulated aerial cable, since kernel cable core and multiple outer layer cable cores can transmit electric power,
Therefore the ability of its total transmission electric power is stronger, but since the erection of general aerial cable is hanging, this also exists
Generally set up the shortcomings that unstable and tension drop resistant effect is bad.
Therefore it is simple in structure to be badly in need of one kind, it is easy for installation, and can not only more to stablize when cable is vacantly installed, drop
Twisted phenomena caused by low wind-force, but also the crosslinked polyethylene insulated aerial cable that there is certain drop resistant to beat ability.
Utility model content
The purpose of this utility model is to provide a kind of crosslinked polyethylene insulated aerial cable, simple in structure, easy for installation, and
It can not only more to stablize when cable is vacantly installed, reduce twisted phenomena caused by wind-force, but also resist with certain
Beat ability.
The utility model provides following technical solution：
A kind of crosslinked polyethylene insulated aerial cable, including the cable conductor, shielded layer, insulation set gradually from inside to outside
Layer, elastic cord breaker and restrictive coating, insulating layer are cross-linked polyethylene layer, and elastic cord breaker is fine for the aramid filament that braiding forms
Layer is tieed up, restrictive coating includes inner sheath and the oversheath being set on the outside of inner sheath, and it is semicircular that oversheath, which includes cross section,
Elastic region and the installing zone that cross section is isosceles trapezoid, installing zone is integrated with elastic region to be connected, and installing zone and elastic region
Between be formed with package inner sheath cavity volume, between installing zone and inner sheath be equipped with fastener, and installing zone it is interior be equipped with it is several
Reinforcing rib.
Preferably, shielded layer is to have a tinned copper wire woven mesh layer and a double layer screen layer that aluminum-plastic composite membrane is composed, real
The double layer screen effect for order wire body is showed so that the antijamming capability of cable is stronger.
Preferably, oversheath is polyethylene and ethyl vinyl acetate copolymer extruded mixture so that oversheath has better
Wearability.
Preferably, fastener is steel tendon so that it will preferably can not only be fixed between inner sheath and oversheath, but also
Also increase the weight of cable installing zone one side so that stablizing effect is more preferable.
Preferably, reinforcing rib is steel tendon so that can enhance the weight of installing zone one side so that can increase cable
Stability.
Preferably, oversheath is equipped with several ventholes so that can enhance electricity on the basis of cable wear resistance is ensured
The gas permeability of cable.
Preferably, cable conductor is copper conductor.
The beneficial effects of the utility model are：By setting inner sheath and oversheath, so as to enhance the wear-resisting of cable
Property, it is arranged to cross section by the way that oversheath is arranged to the unbalanced installing zone of weight and elastic region, and in installing zone as isosceles
Trapezoidal structure, so as to can not only realize the stability of one side Plane Installation of cable and the convenience of installation, Er Qietong
The uneven design of gravity is crossed, caused by can preferably reducing wind-force the phenomenon that cable distortion, and cable can also be enhanced
Drop resistant beat ability.
