Accident, it is ensured that life safety, but existing aerial cable waterproofness is poor, and when installation does not pay attention to that cable is easy to cause to intake, water meeting
Conductor is penetrated into along the gap between conductor, so that aluminium core is generated oxidation reaction, to increase the power consumption of cable；It is existing
Cable is all made of cored mode, and when folding and unfolding is easy that aluminium core is enabled to fracture in winding process, reduces cable service life.
Utility model content
The purpose of this utility model is that being directed to above-mentioned situation, a kind of aluminium core that waterproof performance is good, not easy to break is provided
Overhead insulating water repellent electric cable.
The technical solution of the utility model is achieved in that a kind of aluminium core overhead insulating water repellent electric cable, including conductive aluminum
Core and sheath, the conductive aluminium core are twisted bunchy shape around central axis steel strand wires equipped with conductive aluminium core described in four, four
At cable core, conductive aluminium core outer layer described in four is coated with braiding layer, stays between conductive aluminium core and steel strand wires described in four
There is gap, in the gap filled with the filled layer that blocks water, the filled layer outside that blocks water is equipped with internal shield, the interior screen
It covers and is equipped with water resistant tree insulating layer on the outside of layer, the water resistant tree insulating layer outside is equipped with external shielding layer, outside the external shielding layer
Side is equipped with sheath, and the jacket outer surface is equipped with nanoparticle coat.
In a kind of above-mentioned aluminium core overhead insulating water repellent electric cable, the braiding layer is that the glass fiber yarn of PTFE emulsion is compiled
It knits.
In a kind of above-mentioned aluminium core overhead insulating water repellent electric cable, the internal shield and external shielding layer are that cross-linking type is partly led
Electrical shielding material.
In a kind of above-mentioned aluminium core overhead insulating water repellent electric cable, the filled layer that blocks water is high hydroscopic resin and water blocking yarn
Filling is formed.
In a kind of above-mentioned aluminium core overhead insulating water repellent electric cable, the internal shield thickness is smaller than external shielding layer thickness.
The utility model has the beneficial effects that: four conductive aluminium cores are twisted bunchy around central axis steel strand wires and form cable
Core, filled with the filled layer that blocks water in gap, steel strand wires can prevent winding during folding and unfolding from conductive aluminium core being enabled to be broken, can
Focus on stress point on steel strand wires, the filled layer that blocks water can effectively prevent water to enter conductive aluminium core, internal shield and external shielding layer
Between the water resistant tree insulating layer that is arranged can further prevent water penetration；Jacket outer surface sprays nanoparticle coat, can be improved
Sheath performance prevents the long-term dust accumulation of jacket surface or water mist, to influence cable performance.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
In figure: conductive aluminium core 1, steel strand wires 2, the filled layer 3 that blocks water, braiding layer 4, internal shield 5, water resistant tree insulating layer 6, outer
Shielded layer 7, sheath 8, nanoparticle coat 9.
Specific embodiment
A kind of aluminium core overhead insulating water repellent electric cable as shown in Figure 1, including conductive aluminium core 1 and sheath 8, the conductive aluminum
