METHOD OF ELECTRIC CONDUCTOR MANUFACTURING Russian patent published in 2013 - IPC H01B7/00 

FIELD: electricity.

SUBSTANCE: method of electric conductor manufacturing includes introduction of an additive consisting of a mix of heat-resistant organosilicone fluid (OSF) and heat-resistant fluororganic compound (FOC) in the amount of 0.3-1.5% by weight into granulate of radiation-synthesized compound based on copolymer of tetrafluoroethylene and ethylene. Proportion of OSF and FOC varies within limits of 1:3 up to 3:1. The obtained mixture of granulate and additive is delivered to a loading hopper of the extrusion machine, thereafter at least one coating of this mixture is applied as insulation to electric conductor and irradiated. Electric strength of conductor is more than 70 kV/mm.

EFFECT: improving manufacturability and productivity of the suggested method due to exclusion of destruction of radiation-synthesized compound at growth rate of its application to conductor, high physical and mechanical and electrical properties of insulation.
