| X3860. 2.12.30. X.3860. MACONITE H.T. CABLE Seven lengths of chassis Maconite H.T. ignition cable cut from seven coils on production have been handed to us for test. After 24 hrs. immersion in water at atmospheric temperature these withstood 19,400 volts R.M.S. for 30 mins. applied across the dielectric. HEW. These may therefore be considered O.K. on test.
