In the mid-thirties leading Companies from all over the world had submitted designs for test to the K. E.M.A. Testing Organization at Arnhem in Holland in connection with a project for an 88 kV three phase inter connector between Rotterdam and the Hague (9, 19). Later the required voltage was increased to 150 kV with a view to extending the network to link the principal undertakings throughout Holland, and the testing facilities at K.E.M.A. were enlarged accordingly, tests being carried out on a further range of cable including four gas pressure types. The results of these tests showed clearly that the non-diaphragm type of gas pressure cable could be employed with complete confidence at these extra-high voltages. Unfortunately, the outbreak of war in 1939 brought the Dutch project to an abrupt conclusion. An interesting sidelight to this account, however, is the fact that during a visit to Arnhem after the cessation of hostilities, Mr. P. R. Hartshorn found the Callender Store at the K.E.M.A. Laboratories still intact, despite the considerable activity in the area during the latter part of the war.
