FIELD: manufacturing technology.SUBSTANCE: invention relates to cable industry, in particular to production of enamelled wires. In method performing application of enamel insulation film on wire by anaphoresis at current density j of 2÷10 mA/cmwith subsequent heat supply to wire coated with enamel insulation. At that, during application of enamel insulation film moving wire section with length of L is immersed into electrophoretic compound, wire is stopped, suppled with positive potential, which value provides anaphoresis current value of I, equal to I=πDLj, where D is wire diameter, m, and with said current value depositing enamel insulation film on wire section immersed into electrophoretic compound for certain period of time. At that, for application of enamel insulation electrophoretic compound is used consisting of following components, pts.wt: polyglyceroethyleneterephtalate resin 46.0-48.0, 45-50 % polybutyltitanate in xylene 1.4-1.7, diethylene glycol 0.1-5.0, xylenol 51.6-53.0, solvent 9.3-19.0, dioxane 64-70, 1 % aqueous ammonia 22-24, boron nitride nanotubes 10-12.EFFECT: invention enables increasing in heat conductivity and electrical strength of applied enamel insulation.1 cl, 1 tbl |
