The first PE protective layers connection outside steel strand wires inside drag-line.
Maximum range between first strand of helix and second strand of helix is 4~6 times of 1 diameter of suspension cable.
By adopting the above scheme, the beneficial effects of the invention are as follows：
Bridge provided by the invention and building structure suspension cable deicer, by suspension cable surface layout resistance
Silk, and be wrapped in the form of helical lines on suspension cable；The present invention can improve suspension cable surface temperature by resistance wire heat production
Degree causes suspension cable surface ice sheet to melt, and prevents suspension cable from bearing larger ice load, and can have with helical wire form arrangement
Effect reduces the problem of suspension cable wind and rain resonance, can be widely used on bridge and the suspension cable of building structure.
The present invention is due to using Resistant heating suspension cable surface, surface temperature being increased to more than ice and snow fusing point, ice and snow
Ice and snow load will be substantially reduced after thawing.
The present invention does not influence existing suspension cable shape, and on suspension cable aerodynamic Measures without influence, resistance wire is put into helix
In, the existing shape with spiral shape drag-line is not interfered with so, while the shape of helix will significantly improve suspension cable and inhibit wind
The ability of rain resonance.
The present invention is using low voltage and direct current, and safety is secure, and voltage is controlled below safe voltage 36V, prevents personnel
The contingencies such as electric shock.
The present invention adjusts current conditions equipped with intelligent temperature control device, according to temperature, after ice and snow largely melts can and
When close electric current, it is energy saving.
