Abstract
An electrical cable including four copper layers, where at least two of the four copper layers are separated by a polymeric base layer, and where at least two of the four copper layers are separated by an adhesive. The electrical cable further includes a polymeric cover layer adhered to an outermost copper layer.
Claims19
An electrical cable comprising:
- first and second cores, each core including a polymeric base layer sandwiched by top and bottom copper layers;
- an adhesive layer between the first and second cores and bonding the first and second cores together;
- a first polymeric cover layer bonded to an outer surface of the first core, and a second polymeric cover layer bonded to an outer surface of the second core;
- and
- wherein two innermost copper layers of the electrical cable are ground copper layers, and wherein two outermost copper layers of the electrical cable are active copper layers.

An electrical cable comprising:
- a top polymeric cover layer adhered to a first core, the first core comprising a first copper layer and a first polymeric base layer;
- a second core bonded to the first core, wherein the second core comprises a second polymeric base layer sandwiched between a second copper layer and a third copper layer;
- a third core bonded to the second core, the third core comprising a fourth copper layer and a third polymeric base layer;
- a bottom polymeric cover layer adhered to the third core;
- and
- wherein the second copper layer and the third copper layer are two innermost copper layers and are ground copper layers, and wherein the first copper layer and the fourth copper layer are two outermost copper layers and are active copper layers.
3 more elements
An electrical cable comprising:
- four copper layers, wherein at least two of the four copper layers are separated by a polymeric base layer, wherein at least two of the four copper layers are separated by an adhesive, wherein two innermost copper layers of the four copper layers are ground copper layers, and wherein two outermost copper layers of the four copper layers are active copper layers;
- and
- a polymeric cover layer adhered to an outermost copper layer.
