Abstract

The high frequency eddy current inductor has at least a loop of several insulated conductors which are connected in parallel at their respective connection terminals. The conductors are stranded together to from a wire which is divided into insulated conductors. Each conductor is insulated by a double layer consisting of synthetic varnish layer covered by a thin thermoadherent, chemical plastic material. The wire has an input end (16) and ab outlet end (17). The whole winding is tied together by an exterior agent (12, 13).
