System electromagnetic wave-shielding channel parts for forming of an electromagnetic wave-shielding channel system for electrical conductors and a method for the manufacturing of the parts in the system

摘要

The invention provides a system of electromagnetic parts which form an electromagnetically shielded channel system for electric cables. Tubular parts are provided of a single piece structure, which are extruded from plastic materials and have several layers, including an inner layer of electrically insulating plastic material. There is at least one outer layer of electrically conductive material.
