Abstract: THIS APPLICATION DISCLOSE INSULATED ELECTRICAL CABLES AND METHOD OF MAKING THEM. THE CABLES CONSIST OF METALLIC CONDUCTORS STRANDED OR SOLID, A SEMI-CONDUCTING SHIELD OVER THE CONDUCTOR, A COMPARATIVELY HEAVY WALL OF INSULATION AND ANOTHER LAYER OF SEMI-CONDUCTING SHIELD WHICH, IF USED IN SUFFICIENT THICKNESS, MAY SERVE BOTH AS A SHIELD AND AN OUTER PROTECTIVE JACKET. THE CABLES ARE IRRADIATED IN A PARTICULAR CONTROLLED MANNER TO IMPROVE DESIRED PHYSICAL CHARACTERISTICS WHILE PRESERVING DESIRED INSULAATING CHARACTERISTICS. THE INVENTION IS PARTICULARLY APPLICABLE TO HIGH VOLTAGE CABLES RATED 5 TO 70 KV. OR ABOVE.
