摘要:
A telecommunications conductor is produced by coating it with a visco-elastic dielectric material and then providing an electrically conductive material around the conductor by bombarding the visco-elastic material with particles of the conductor material and changing the visco-elastic material into hardened form. A shielding layer is provided by causing the particles to adhere to the surface of the dielectric material and when the particles provide a conductive path, the layer is completed by applying conductive material by electrolytical deposition or by plasma coating. Alternatively in an insulated conductor provided with a continuous inductive loading, the particles are caused to enter into and become discretely embedded within the visco-elastic material.

Method of making insulated conductor wire in which a homogeneous mixture of a dielectric carrier and magnetically permeable particles is sprayed onto the wire to deposit a layer of the mixture on the wire. The layer is then hardened to provide an insulating layer with the particles substantially uniformly dispersed therein.
摘要:
In providing a dried insulation layer upon conductor, a covering fluid layer is initially provided by apparatus in which the layer is formed from composite material comprising magnetically permeable particles homogeneously mixed with a fluid carrier. The fluid layer is formed by passing the conductor through a reservoir of the material and then vertically through a die orifice. The reservoir of fluid applies pressure at the die orifice and this pressure is adjustable to vary the rate at which the material passes through the orifice and thus varies the diameter. This pressure is controllable by adjusting the height of the reservoir above a die orifice or by adjusting gas pressure acting downwardly upon the material. The diameter of the layer is advantageously monitored after it is dried and variation in monitored diameter from that desired effects a change in pressure to alter the diameter towards that desired. The diameter of the layer may, however, be monitored with the layer in fluid form.
