| X3860 PN{Mr Northey}2/DN14.5.26. TO EFC FROM PN{Mr Northey} Maconite insulated H.T. cables for chassis. With reference to your report on this new insulated material, on testing the piece you sent to me, I found that it is very easily inflammable. This, of course is not in its favour. Have you ascertained at what temperature this insulation becomes sufficiently softened to enable the conductor to become eccentric? P.N. | ||
