Lauchammer Company, Saxony The power supply situation in Germany is complicated bythe fact that not only are there no easily-developed water-powers in the country, but the coal supply is very poor. Dur-ing the war these resources have been developed to theirutmost, and most of the great nitrate and other electro-chemical works are supplied with electricpower, transmitted from the mines. Shortly before the warthe first undertaking of this kind was iput into operation,namely, the system of the Lauchammer Company, Saxony,and it may be assumed that a large number of similar instal-lations of the same kind are now The Lauchammertransmission was the first line in Europe. Poweris raised from the soft coal known as braunkolil,. Fig. 23. On the 150-foot right of way of the Pacific Light and Power150,000-volt lines. which is consumed at the mine location. To transport this coalit must be compressed into briquettes; it was therefore foundto be an economical proceeding to generate electric power andtransmit that instead. A double-circuit line conveys thepower to Groditz and Riesa a total distance of 34 miles. Thevoltage is very high in comparison with the length of line,but the reason given by the engineers of the line was thatonly suspension insulators could be considered, on accountof the liability of the pin type to damage due to mischief orother causes. Having adoipted suspension units, there was noobject in setting a lower voltage than the one chosen. It is,however, more liljely that this undertaking was intended as 30 THE ELECTRICAL NEWS hine 1.
