The utility model discloses a stride across protection network for transmission line erects construction, including a plurality of insulating carrier cables with connect the safety net between the insulating carrier cable of double -phase neighbour, laid two -layer buffering safety belt in clearance at least in this safety net top, each tip that cushions the safety belt all with the insulating carrier cable rigid coupling that corresponds, each cushions the safety belt and takes to personally experience sth. Part of the body by two sections and form through the hasp adhesion. The utility modeldiscloses an at least, two -layer buffering safety belt is adhered to in the clearance above current safety net, and it is formed through the hasp adhesion by two sections area bodies to cushion thesafety belt, form braced chain formula appearance, utilize the successive layer to absorb, the principle that buffering fracture thing strikes kinetic energy, adhesive force by the hasp adhesion absorbs the impact kinetic energy that cushions the fracture thing, reduce the fracture thing speed of falling, can be under the condition that does not change the construction side method, it is direct inthe face of fracture thing impact changing into fracture thing through the buffering to make original safety net, bear by the safety net again behind the energy -absorbing, thereby greatly increase the scope that the safety net endured the impact.
