Abstract：
In order to increase the wettability of the surface of the high voltage transmission line and reduce the audible noise caused by corona discharge, the surface of the high voltage transmission line after sand blasting treatment was first alkaline pre-plating, followed by acid electroless Ni-P plating treatment, and the chemical Ni-P coating with rough surface and thickness of 0.1 mm was obtained. The results show that the hardness of electroless plating is 1 100 HV, the wetting contact angle of the coating surface is 23.5°. The electroless Ni-P coating with high hardness and roughness improves the surface tension of liquid on the surface of the high voltage transmission line, increases the wettability of the surface of the high voltage transmission line, does not easily produce water droplets, and reduces the audible noise caused by corona discharge.
