Embodiment Construction
[0010] The present invention will be further described below in conjunction with embodiment:
[0011] Such as figure 1 As shown, a kind of anti-icing power transmission cable 1 is coated with n-hexadecane hydrophobic layer 2 on the surface of power transmission cable 1. Surface microstructure width a=2~4μm, microstructure spacing b=4~6μm, microstructure height h=4~6μm, fractal nanostructure width a’=100~150nm, nanostructure spacing b’=200~300nm , the nanostructure height h'=150-250nm.
[0012] A kind of production method of anti-icing power transmission cable, utilizes the evaporation coating technology in the physical vapor deposition method (PVD) to coat the surface of the power transmission cable, put the cable bare wire (aluminum-clad steel strand, copper-clad steel wire, etc.) into a vacuum Room (-5 ), put the evaporation source material n-hexacane into the heater, slowly increase the temperature of the heater until the evaporation source material is completely liquefie...
