Silver plated. Slip rings used in wind power are mainly used for rotating shaft transmission and signal transmission. Due to the complex environment of wind power, slip rings must have wear resistance, corrosion resistance, conductivity and other properties, so the surface of the slip ring is. usually treated with special treatments. In some cases, the surface of the slip ring may be silvered to increase its conductivity and corrosion resistance.
Gold and silver. According to relevant public information requests, precious metals commonly used in wind power slip rings include silver and gold. This is because silver has good electrical and thermal conductivity, can transmit electrical signals and energy efficiently, and is relatively cheap. Gold, on the other hand,is a higher quality conductive material that can ensure the stability and reliability of electrical signal and energy transmission, but its price is relatively high.
