Hooper's patent submarine telegraph cables, 1862. Creator: Unknown

Hooper's patent submarine telegraph cables, 1862. Mr. Hooper's cable is composed of the usual copper or other conductor insulated with indiarubber, which is now generally admitted to be by far the best material on account of its high insulating quality, its low inductive capacity, and its being unaffected by the heat of tropical climates...inclosing the indiarubber insulated wire within a jacket or coating of vulcanite or vulcanised indiarubber...decomposition [is prevented], as the indiarubber...becomes firmer by time...Another feature...is the protection of the wires used for tensile strength from corrosion or oxydation...Mr. Hooper either imbeds these wires in the vulcanite or vulcanised indiarubber jacket, or he covers them separately with either of these materials, and thus perfectly protects them from corrosion or decay. Figs. 1 and 2 show longitudinal sections of two forms of cable. Fig. 1: a, conductor; b, indiarubber insulator; c, separator; D, vulcanite or vulcanised indiarubber; e, f, wires for tensile strength imbedded in vulcanite or vulcanised indiarubber. Fig. 2 : a, conductor ; b, indiarubber insulator; c, wires or cords for tensile strength; d, protector of vulcanite or vulcanised indiarubber'. From "Illustrated London News", 1862

EDITORS COMMENTS
This image showcases Hooper's patent submarine telegraph cables from 1862, a groundbreaking innovation in underwater communication technology. The creator of this design remains unknown, but the intricacies of the cable's construction are vividly depicted in this illustration from the Illustrated London News. At the heart of Hooper's cable design lies the use of indiarubber insulation, which had gained widespread acceptance due to its superior insulating properties, low inductive capacity, and resistance to tropical heat. The indiarubber-insulated wires were encased within a jacket or coating of vulcanite or vulcanised indiarubber, preventing decomposition and making the cable more durable over time. Another notable feature of Hooper's cable design was the protection of the wires used for tensile strength from corrosion or oxidation. This was achieved by either embedding these wires within the vulcanite or vulcanised indiarubber jacket or covering them separately with the same protective materials. Figures 1 and 2 in this illustration provide a detailed look at the longitudinal sections of two forms of Hooper's cables. In Figure 1, the conductor (a) is insulated by indiarubber (b), with a separator (c) and a vulcanite or vulcanised indiarubber jacket (D) surrounding the insulated wire. Wires for tensile strength (e and f) are imbedded within the vulcanite or vulcanised indiarubber. In Figure 2, the conductor (a) is insulated by indiarubber (b), with wires or cords (c) for tensile strength and a protector (d) of vulcanite or vulcanised indiarubber. This photograph offers a fascinating glimpse into the engineering marvels of the past, showcasing the intricate details of Hooper's submarine telegraph cables that revolutionized long-distance communication.
