Abstract
Abstract An insulated stranded conductor which is properly fluid blocked is manufactured by first coating a wire filament or strand, and then forming a stranded conductor with the coated filament as the center strand. An outer insulation is applied over the resulting stranded conductor under sufficient pressure to at least partially fill the interstitial spaces between the strands. The coating and insulation are formed of a curable polymeric composition, and the two materials, being in intimate contact, are cured at an elevated temperature and upon cooling, bond to each other, thereby substantially encapsulating all the strands of the conductor.
