| EFC. WD.{Mr Wood/Mr Whitehead}101. COPY 3.5.28. SAMPLES OF GLOVER H.T. CABLE SUBMITTED BY ROX/CEA. FOR TEST. The two samples sent were believed to be faulty or poor quality by the external appearance of the rubber. We immersed one sample in water for 16 hours and tested it at a high A.C. potential. This sample immediately broke down when a voltage of 19000 R.M.S. was attained. The other sample was not soaked at all but tested immediately after immersing in the tank and it also broke down after 3 minutes at 19000 volts R.M.S. We consider these samples to be of poor quality even compared with other samples of Glover cable. EFC/H.E.West. | ||
