Oil Insulators used in Spain

Polyphase Currents in Spain.— The two neighbouring towns of Elgoibar and Eibar, in Spain, will shortly have installations of polyphase-current plant for light and power. The work is being carried out by Messrs. Siemens and Halske, using the power of the River Deva, which, with about 30ft. fall, gives 300 available horse-power. Hercules turbines are used at 200 revolutions, driving a 80-kilowatt "Drehstrom" dynamo. The current generated at 120 volts will be transformed up to 5,000 volts, and conducted by overhead wires on oil insulators to the two towns situated one and three miles distant respectively. About 60 incandescent lamps will be used in the streetlighting in Elgoibar, and several hundred private lights. In Eibar, an industrial town, 120 lamps will be required for street-lighting, and 400 lamps for private lighting are ordered. Electromotors of from 1 h.p. to 25 h.p. will be installed for transmission of power. Don Ermanno Schilling is the Madrid agent who has carried out the details of this installation.
