Abstract
1306742 Coated conductors BRITISH INSULATED CALLENDER’S CABLES Ltd 14 Jan 1971 [16 Jan 1970] 2290/70 Heading B2E [Also in Division H1] A method of manufacturing a high voltage insulated electric conductor comprises applying to a conductor an insulation of an ethylene polymer at least 2.5 mm. thick and crosslinking the insulation by subjecting it with high energy radiation, preferably electrons, to cause it to absorb a dose D Mrad in the range 20 to 60 or 25 to 55 Mrad at an average rate R Mrad/sec. The irradiation conditions are represented by a point on Fig. 1 below the curve C’B’DD’ which approximately defines the boundary between sucessful (below the curve) and unsuccessful (above the curve) tests on samples of irradiated cables, or possibly by a point only in the region represented by the expansion R # e
