Abstract
A composite wire which consists of a number of preferably parallel extending single wire strands bundled to form one solid assembly at least one of which is a bare wire. The composite wire (8) is formed from a bare wire (15) around whch a number, for example, five, or more, single wire strands (9-14) having a thin insulating layer are arranged in the form of a bundle. The assembly is surrounded by a layer of an electrically insulating material, which itself may be surrounded by a layer of a thermoplastic material. The composite wire is particularly suitable for winding saddle-shaped deflection coils for deflection units for cathode ray tubes.

A composite wire for high-frequency applications, comprising:
- at least one bare wire strand and a plurality of single wire strands of electrically conductive material;
- each of the single wire strands having a thin insulating layer and extending in pre-determined parallel positions with respect to each other and parallel to the length of the composite wire;
- all of said wire strands being bundled to form a solid assembly;
- and a layer of electrically insulating material enveloping such solid assembly.
A cathode ray tube deflection coil of the saddle type wound from a composite wire, such composite wire comprising:
- at least one bare wire strand and a plurality of single wire strands of electrically conductive material;
- each of the single wire strands having a thin insulating layer and extending in pre-determined parallel positions with respect to each other and parallel to the length of the composite wire;
- all of said wire strands being bundled to form a solid assembly, and a layer of electrically insulating material enveloping such solid assembly.
