Ernst Kuhlo

Ernst Kuhlo (born November 19, 1843 in Stargordt , Regenwalde district , † January 20, 1923 in Stettin ) was a German electrical engineer and founder of the Stettiner Electricitäts-Werke . He became known for the development of the Kuhlo tube (also called the Kuhlo cable).

Live and act

Kuhlo was born the son of a pastor in Stargordt in Western Pomerania . He attended the Friedrich Wilhelms School in Stettin and then did an apprenticeship as a mechanic in Königsberg i. Pr. In 1869 he founded a company in Stettin that took over the representation for Siemens & Halske and for the German Edison Society in the 1880s . He equipped important Pomeranian companies such as the Vulcan shipyard in Stettin and the Pommersche Provinzial-Zucker-Siederei with electric lighting .

Also in the 1880s, Kuhlo installed street lighting in Stettin on behalf of the city, for which he founded the Stettiner Electricitäts-Werke . From 1890 these were run as a stock corporation with a share capital of M 1.2 million. In 1911 the city of Stettin took over the electricity supply into its own hands, with Kuhlo working as director until 1920.

Kuhlo was married; the marriage produced four sons and five daughters. His son Franz Kuhlo became head of the Stettiner Electricity Works in 1920.

Kuhlo pipe

Kuhlo developed a pipe and sheathed wire, which for decades was a leader in the laying of electrical lines in the household and industry. This "Kuhlo pipe" was introduced on a large scale by Siemens-Schuckertwerke . Because of a similar invention, the miner pipe, the Kuhlo pipe was not patented.

The description in a technical encyclopedia from 1920 reads: “Pipe wires, Kuhlo system (also called folded wires) are rubber core cables with a metal jacket. The metal jacket in the form of sheet brass or leaded iron sheet is placed tightly around the pipe (...), so there are no cavities in which air can circulate. The wires can be easily bent with the help of bending pliers, and bending points with a radius of curvature of only six times the pipe diameter can still be carried out cleanly. They are (...) designed as single and multiple lines; the metal jacket can be used as a bare neutral conductor. The pipe wires are attached to the wall in a simple manner using clamps. "
