First cross-Channel telegraph cable. Historical artwork of the composition of the first telegraph cable linking England and France. This was laid in 1851 by the British engineer Jacob Brett. It ran between Dover,England,and Calais,France. Two attempts to lay a telegraph cable under the English Channel,in 1847 and 1850,had both failed. Advances in insulation technology ensured that the third attempt was successful. Gutta- percha rubber was used to insulate the four conducting wires (seen at upper centre). The success of this cable meant that Britain could be connected to the European telegraph system | |
