Utility poles seen outside the Gardner Building, in Toledo, Ohio, 1895. The system of suspending telegraph wires from poles with ceramic insulators was invented and patented by British telegraph pioneer William Fothergill Cooke. Cooke was the driving force in establishing the electrical telegraph on a commercial basis.
Oppenheimer poles can still be found along the route of the former Australian Overland Telegraph Line, and in Queensland and Western Australia. Oppenheimer poles can also be found repurposed as flag poles, or in the case of the William Creek Hotel, as verandah supports. There is also an Oppenheimer pole outside the Daly Waters pub.

To connect the telegraph to anywhere outside Britain, submarine telegraph cables were needed. The lack of a good insulator held back their development. Rubber was tried but degraded in salt water. The solution came with gutta-percha, a natural latex from trees of the genus Palaquium in the Far East. It sets harder than rubber when exposed to ...
A metal pole and cyclone wire fence bounds the front of the property in approximately the same location as earlier fences (according to early photographs). A remaining telegraph pole stands just behind this fence, roughly centered on the eastern facade of the former Office building. [1]
The Humberston Fitties (officially named the Humberston Fitties Chalet Park [1] and known locally as The Fitties) is a holiday resort that began as an inter-war plotland in the civil parish of Humberston, in the North East Lincolnshire district, in the ceremonial county of Lincolnshire, England.
Early undergrounding had a basis in the detonation of mining explosives and in undersea telegraph cables. Electric cables were used in Russia to detonate mining explosives in 1812, and to carry telegraph signals across the English Channel in 1850. [1] With the spread of early electrical power systems, undergrounding began to increase as well.
It consists of a 17 m wooden telegraph pole standing on a hillside which is itself about 220 m above sea level. The transmissions are beamed southwest and northwest to cover all the small settlements of the area and to provide a signal for the Llansawel repeater about 5 km to the northwest.
Installation of the lines and poles from Washington to Baltimore began on April 1, 1844, using chestnut poles 23 feet (7 m) high spaced 300 feet (90 m) apart, for a total of about 700 poles. [6] Two 16- gauge copper wires were installed; they were insulated with cotton thread, shellac, and a mixture of "beeswax, resin, linseed oil, and asphalt."
