Abstract
An electrically-conductive sheet-form laminate is disclosed and a power cable made thereof. The laminate has a resistivity of no more than about 10.sup.6 ohm-centimeters across the thickness dimension thereof. The sheet-form laminate comprises an electrically-conductive non-metallic layer, an electrically-conductive metal foil layer in juxtaposition thereto, and a discontinuous but electrically non-conductive bonding layer therebetween. The electrically-conductive non-metallic layer is constituted by a particulate conductive material-filled polymeric resin; and the electrically non-conductive bonding layer comprises a cured polymeric substance, preferably a polyurethane-based adhesive.
Claims8
An electrically-conductive sheet-form laminate having a resistivity of no more than about 10.sup.6 ohm-centimeters across the thickness dimension thereof and comprising:
- an electrically-conductive non-metallic layer;
- a metal foil layer in juxtaposition thereto;
- and
- a discontinuous but non-conductive bonding layer therebetween;
- said non-metallic layer being constituted by a particulate conductive material-filled polymeric resin;
- and
- said bonding layer comprising a cured polymeric substance.
In a power cable which includes an electrically-conductive core, insulation surrounding the core, and a jacket surrounding the insulation,
- the improvement which comprises:
- an electrically-conductive sheet-form laminate having a resistivity of no more than about 10.sup.6 ohm-centimeters across the thickness dimension thereof, the laminate being positioned between the insulation and the jacket and providing a moisture barrier therebetween,
- the electrically-conductive laminate layer comprising:
- an electrically-conductive non-metallic layer;
- a metal foil layer in juxtaposition thereto, and
- a discontinuous but non-conductive bonding layer between said non-metallic layer and said metal foil layer;
- said non-metallic layer being constituted by a particulate conductive material-filled polymeric resin;
- and
- said bonding layer comprising a cured polymeric substance.
