Abstract
A downwell pump three-phase power cable containing three power conductors each provided with at least one extruded polymeric insulating layer made of an insulating polymer selected from an ethylene copolymer or a fluoropolymer, a metal tube in radial external position with respect to the insulating layer, and an extruded encapsulating layer embedding the three power conductors and made of a fluoropolymer.
Claims13
A downwell pump three-phase power cable, comprising:
- three power conductors each provided with at least one extruded polymeric insulating layer, made of an insulating polymer selected from ethylene copolymer or fluoropolymer;
- three metal tubes wherein each metal tube individually encapsulates each of the three power conductors and is set in radial external position with respect to the insulating layer;
- and
- an extruded encapsulating layer embedding the three metal tubes and made of a fluoropolymer, wherein said extruded encapsulating layer is the outer-most layer of said power cable.
