Abstract (en)
[origin: GB2318691A] An inductor and a method of its manufacture is disclosed in which the inductor is suitable for use in a filter arrangement separating or combining low frequency mains electricity signals and high frequency telecommunication signals for transmission on a network. The inductor comprises an elongate conductor 10 with at least pert of the conductive bar being surrounded by a sleeve 20 such that there is substantially no electrical conduction path through the sleeve 20 in a direction away from the conductor 10. The conductor 10 may have a rectangular cross section and the sleeve 20 may be made from a magnetically permeable material such as ferrite to reduce the skin effect which occurs at high frequencies. Insulating material may be used to separate a sleeve which is made from a semiconductive or conductive material from the said elongate conductor 10.
