Wind energy converter commonly converts wind power to shaft and electric power. One of the problems of transmitting shaft power is the limited distance between the driving to the driven shaft. This paper describes an experimental study of electrical transmission from driving to the driven shaft that was carried out on three modes of cable lines transmission. The driving shaft was attached to an electric generator that converts shaft r to electric power. The driven shaft was coupled by electric motor which reconverts the electric to shaft power. The generator and motor were BLDC and BDC permanent magnet electric machines. The distance of the driving to the driven shaft was 300 meters. The electric power was transmitted using wires. The wires consisted of 2 and 3 cables commonly used by peoples and sold in market place. The results showed that electric transmission mode on the experiment has important role on performance of shaft power to electric power conversion on driving generator and energy losses on cables transmission. DC on small wires electric transmission gave total efficiency of 16.2 %. DC on large wires electric transmission gave total efficiency of 32.9 %. AC on large wires electric transmission gave total efficiency of 36.4 %.
