Abstract
A protective sheath for protecting and separating a plurality of insulated conductors from a single cable includes a layer of protective armor surronding all of the conductors extending from down hole along production tubing in an underground well. The protective armor terminates at a separating point of the cable conductors so that the plurality of cable conductors are separated into individual cable conductors. The sheath includes a hollow tube for enclosing the plurality of insulated cable conductors and protective armor. A plurality of individual tubes are formed integrally with and endose one end of the rigid tube so that each one of the plurality of cable conductors is routed into a separate rigid tube so that each one of the plurality of rigid tubes encloses a corresponding one of the individual cable conductors. The rigid tube and individual rigid tubes are sized to confine but not engage the conductors when the well is pressurized for preventing excessive expansion of the insulation on the conductors on the well depressurization.
