ELECTRIC CONDUCTOR MULTIPLE-CORD CORE PRODUCTION TECHNIQUE AND ELECTRIC CONDUCTOR MULTIPLE-CORD CORE, MADE BY THIS TECHNIQUE Russian patent published in 2017 - IPC H01B5/08 

FIELD: electricity.

SUBSTANCE: electric conductor multiple-cord core production technique comprises a long-length flexible rods twisting, each of which is preliminarily obtained by the pultrusion method, which includes the continuous carbon fiber strands passing to the impregnation through the circular holes that are located at the central part, and the other continuous carbon fiber strands passing to the circular holes that are located at the peripherical part of the distributing plate, which comprises the noted holes in number that is relevant to the strands number. Then the strands are impregnated with the epoxy binder and are given the thermal treatment. Upon that, the basalt fiber is used in the function of the other continuous fiber, notably the carbon fiber and the basalt fiber are used. The core comprises 60-80% reinforcing fiber of the composite material mass.

EFFECT: breaking strength improvement.
