Layer, insulating layer, first screen layer and glide lamella, the polyvinyl chloride composite layer with a thickness of 0.30~2.00mm, the sliding
Layer is the macromolecule material film layer of low friction coefficient, and several insulated wire cores mutually twist together；It is described it is several with
The outside of insulated wire cores include from inside to outside composite fire layer, inner sheath, soft structure lightning protection layer, secondary shielding layer, ground plane,
Nanocomposite elastomer sheath and bituminous coating, the soft structure lightning protection layer are wire and fiber filament mixed weaving layer, the two
Orthogonal weave reticulates, and is provided with high resiliency gasket for packing and fiberglass plastic in the gap between several insulated wire cores
Ball, both the high resiliency gasket for packing and fiberglass plastic ball are in be staggered；If the outside of the bituminous coating is provided with
Dry triangular hill, several triangular hills are provided on each triangular hill in being symmetrical arranged two-by-two
Fixation hole.
Further, the quantity of the insulated wire cores is at least three.
Further, it is described it is netted for trapezoidal netted, triangular mesh or hexagon it is one of netted.

By adopting the above technical scheme, beneficial effects of the present invention:
On the one hand a kind of wind power generation lightning protection flexible cable, the setting of first screen layer and secondary shielding layer can prevent from leading
On the other hand electromagnetic interference between body can be that the powerful Electromagnetic Field generated generates the double-deck buffer action to lightning stroke；Ground connection
The setting of layer, when being struck by lightning, the instantaneous calorific value meeting very little of ground plane avoids cable from being blown；Nanocomposite elastomer
The bituminous coating being arranged outside sheath, can effectively anti-corrosion and the aging for preventing nanocomposite elastomer sheath；Bituminous coating
External several triangular hills being arranged, in use, cable easily be fixed after fixation hole can be passed through by rivet
In on wall, on the ground or other objects on, since the cable majority is for open air and to carry out lightning protection, so being fixed
The safety that cable uses can be improved；Using nanocomposite elastomer sheath, impact resistance, cold-resistant, tension Zhang Qiang can be increased
The performances such as degree, anticorrosion；Its with it is light it is soft, conduct electricity very well, that corrosion resistance is strong, it is fixed to be easy to, manufacturing cost is low is excellent
Point.
