It is shown that in order to control continuous processes of insulation imposition on conductive copper conductor for each type of symmetrical cable it is necessary to determine a value of linear capacity of isolated conductor. For this purpose analytical expression of working capacitance, allowing to determine size of linear capacitance of cable pair with film-porous polyethylene insulation of cores, has been obtained. On the basis of this research the practical recommendations have been given for adjustment of automatic system of setting up the cable capacity when insulation is applied on an extrusion line.
