The production of ELETTROMIL magnetic components is modulated according to the field of application of the product (natural convection or forced ventilation cooling; degree of protection up to IP65). The enclosed standardizations refer to natural air convection cooled products with an IP00 degree of protection. Depending on the insulation tensions requested, the maximum noise level required and the degree of protection requested, our products are vacuum pressure impregnated with polyester resins without solvents or are encased partially or completely with epoxy or polyurethane resins.
