Further, first oversheath is polyolefin oversheath.Improve UV resistant, the high-low temperature resistant of product
Performance.
Further, the lapping layer and the braiding layer are provided with the asbestos of corrugated.The asbestos of the corrugated
Not only can buffer but also can be with fire-retardant.
Further, the cross section of second oversheath is equilateral triangle, its three sides and first oversheath
It is tangent.Triangle is most firm shape, and second oversheath is unlikely to deform so that cable internal structure is more firm, no
Easily change, extend the service life of cable.
Further, second oversheath in the gap of first oversheath with being provided with polymer mix.The suction
The globule pins moisture, prevents moist inside cable.
Further, it is provided with heat sink strip between the braiding layer and first oversheath.The heat sink strip can dissipate
Heat is removed, prevents cable spontaneous combustion.
Beneficial effect：New reinforced aerial insulated cable of the present utility model, the strengthening core and core set exhausted outside
