INSULATION OF CONDUCTORS WITH IMPROVED SEPARABILITY FROM PROCESSED BROKEN STONE

摘要

The invention deals with insulation with improved separability from the processed broken stone designed as single-layer or multi-layer insulation surrounding an electric conductor where the principle is that at least one layer of the insulation is made of magnetic material and at the same time at least one layer is made of electrically non-conductive material. The content of the magnetic main material component in individual insulation layers is 5 to 60% of weight and the rest to 100% consists of the non magnetic main material component, all related to the weight of individual layers. The magnetic main material component is beneficially produced on the basis of magnetite - Fe3O4 or on the basis of ferrite with the general formula Me"Fe204, where Me represents Co, Mn, Ni, Ca, Cu, Zn, Mg, or ferrite withe the general formula Ln"Fe204, whre Ln represents noble earth elements, or on the basis of noble earth elements in the oxidation degree II, or on basis of ferric oxide in the modification y-Fe2O3, or on basis of powder iron, or on basis of magnetic alloy of iron or on the basis of a mixture or alloy containing the above magnetic components
