Editing Loading coil (section)

===Krarup cable===
A Danish engineer, [[Carl Emil Krarup]], invented a form of continuously loaded cable which solved the problems of discrete loading coils. Krarup cable has iron wires continuously wound around the central copper conductor with adjacent turns in contact with each other. This cable was the first use of continuous loading on any telecommunication cable.<ref>Kragh, p. 129</ref> In 1902, Krarup both wrote his paper on this subject and saw the installation of the first cable between [[Helsingør]] (Denmark) and [[Helsingborg]] (Sweden).<ref>Huurderman, pp. 321-322</ref>
