FIELD: electrical engineering.
SUBSTANCE: method of production of power cable including conductor and ply of polymer coat. This method comprises the steps whereat polypropylene matrix is mixed with dielectric fluid to obtain polymer mix. Hydrodynamic pressure of said mix is increased. Polymer mix is filtered. Said polymer mix is forced through extrusion head to get coat ply on conductor and cable is cooled.
EFFECT: decreased amount of contaminants, process with sufficient rate.
