Pelzer, S. C. transmission line

New Transmission System at Pelzer, S. C.

The Pelzer Manufacturing Company, of Pelzer, S. C., has contracted with the General Electric Company for a three-phase electric transmission plant that will be exceptionally large and interesting. At the generating station, three miles from the cotton mills owned by the company, there will be three slow speed generators of 750 kilowatts each directly coupled to water wheels. These dynamos will generate current at a potential of 3,300 volts and the current will be fed directly to the transmission wires at this pressure. The transmission line will consist of eighteen No. 00 wires, this size having been selected in preference to larger wire to reduce the line induction as much as possible under the existing conditions. At one mill will be located a 400 horse-power synchronous motor, receiving current directly from the wires. There be, in addition, more than twenty induction motors in various rooms. Of these fourteen will be 110 horse-power motors and the others will be of various sizes, from 5 to 75 horse-power. In a sub-station will be located nine 160 kilowatt transformers for the motors and for 1,200 incandescent lights for the mills. Two electrically operated blowers of 3 horse-power each will be used for cooling the transformers.
