Just previous to the standardisation of Maconite H.T. ignition wires for the chassis we had written a report EFC4/T2.5.28 dealing with the various points of comparison between this cable and the standard (at the time) Glover H.T. cable then in use, also the results of a number of "sandwich" and other tests of Maconite and Glover cable on experimental Phantom I cars. In that report we referred to the submission by Messrs. Glover of other types of H.T. cable namely, Cloverite and Super Clover. In due course we received samples of such H.T. cables and also samples of Helsby H.T. cable supplied by the British Insulated and Helsby cable Co.Ltd. A similar series of comparative tests of Maconite, Gloverite, Super Glover and Helsby cables to those originally done between Maconite and the old standard Glover has now been completed, the tests on the chassis being carried out on a Phantom I chassis 12-EX. A complete series of tests was carried out to our general specification of H.T. cable tests, comprising - | ||
