Cable heat dissipation effect is poor, during cable work, cannot effectively dissipate the heat that conductor generates, lead to conductor temperature
Height is spent, the reduction of its current-carrying capacity is caused.
So needing a kind of high-intensitive aerial insulated cable to solve the problems, such as this.
Utility model content
For above situation, for the defect for overcoming the prior art, the purpose of the utility model is just to provide a kind of high intensity
The problem of aerial insulated cable, effective solution cable vulnerable to friction causes cable that can be damaged.
Its technical solution solved is that the utility model includes special-shaped supporting-core, and the midpoint of special-shaped supporting-core side is all provided with
There is arc groove, three ends of special-shaped supporting-core are fitted with steel strand wires, three electricity are housed at three arc grooves of special-shaped supporting-core
Cable core, special-shaped supporting-core are equipped with multiple locating racks, and locating rack includes first baffle, second baffle and locating shaft, first baffle
Be fixedly connected with one end of second baffle with locating shaft, the other end of first baffle and second baffle respectively with special-shaped supporting-core
End be fixedly connected, be equipped with support frame on first baffle and second baffle, the outside of locating rack and support frame is equipped with armouring
Layer, forms heat dissipation cavity, armor is externally provided with wrapping layer between locating rack, support frame and armor.
The beneficial effects of the utility model are: the utility model is novel, three conductors are integrally attached to special-shaped branch
In support core, and special-shaped supporting-core is fixed by locating rack, so that opposite move will not occur from each other for three cables core
It is dynamic, it avoids cable and is linked to together due to respect to shaking；Core is twisted by three steel being mounted on special-shaped supporting-core and is set
The material for setting sheath and sheath improves the mechanical performance and weather resistance of aerial cable, and the erection for reducing aerial cable is empty
Between area, reduce the Quantity of shaft tower, improve aerial cable erection span and set up intensity.
