Electrical submersible pump cable
An electrical cable comprises a plurality of primary conductors 30, 32, 34, an insulating layer 36, 38, 40 surrounding each of said primary conductors, a coaxial conductive layer 46, 48, 50 surrounding at least one of said inner insulating layers, an outer insulating layer 52, 54, 56 on an outer sur...

Summary: | An electrical cable comprises a plurality of primary conductors 30, 32, 34, an insulating layer 36, 38, 40 surrounding each of said primary conductors, a coaxial conductive layer 46, 48, 50 surrounding at least one of said inner insulating layers, an outer insulating layer 52, 54, 56 on an outer surface of each coaxial conductive layer, and an outer jacket 64 surrounding all of the inner insulating layers and said outer insulating layer(s). The cable may further comprise inner cable armour 58, 60, 62 surrounding the outer insulating layer. The cable construction may be used as a motor lead extension (see figure 1) to be spliced onto the end of a downhole communication cable for an electrical submersible pump, so that regular cable may be used along the majority of the downhole length (thereby reducing cost), the coaxial and primary conductors enabling the coupling of information onto or off the cable. |
