Abstract (en)

A multiconductor electrical cable (10) for use in a subterranean wellbore includes at least one electrical conductor (12) surrounded by one or more layers (14) of insulating material, such as EPDM. A fluid barrier, such as an extruded layer (16) of lead or a lead alloy, surrounds the insulating material. To protect the fluid barrier from damage during the subsequent armouring process, a non-braided material (18) is applied, as an extrusion or a tape. The non-braided material can be applied immediately after the fluid barrier is applied, not as a separate process, thereby reducing the risk of damage to the fragile fluid barrier, and at a cost less than the braided materials used in the past. <IMAGE>
