ABSTRACT:
The invention concerns an electrically insulating body including at least two polymer materials and a method of making such a body. It is characterized in that its internal structure (61) is mainly formed by a first polymer material and that its surface structure (60, 62) is mainly formed by a second polymer material, said first polymer material having a higher molecular weight than said second polymer material. The proportion in the body of the first polymer material relative to the second polymer material reduces progressively from the internal structure (61) towards the surface structure (60, 62). The invention is applicable especially to insulating electric conductors (26) and enables insulators to be obtained having both a high dielectric strength and a good quality of shape.
