Research on the Anti-corona Coating of the Power Transmission Line Conductor

Abstract

An anti-corona method for the power transmission lines is proposed in this paper. The RTV coating is used as the an-ti-corona coating, which is spaying onto the surface of the wearing conductor. The corona characteristic of the conduc-tor test was done, and the corona onset voltage increase after the spraying of the anti-corona layer, the corona loss in the same voltage decrease, which could prove the excellent effect of improving the corona characteristic of the conductor. This anti-corona method will have great prospect, based on the background of the construction of UHV power trans-mission lines.
