A wire harness that includes an electric wire; a first tube that is made of a metal and covers an outer circumference of the electric wire; a braided wire that is formed by braiding conductive strands into a tubular shape, is attached to an outer circumferential surface of the first tube, and covers an outer circumference of a drawn-out portion of the electric wire, the drawn-out portion being drawn out from an end of the first tube; and a second tube that is made of a metal.

An electrical cable for vertical applications includes a core having a length L, a sheath surrounding the core and extending through the whole length L and a reinforcing jacket surrounding the sheath and in direct contact therewith. The reinforcing jacket is made of concentric layers including a first layer longitudinally extending from a first cable end (the proximal or upper cable end, in use) towards a second cable end (the distal or lower cable end, in use) substantially along the whole length L. The reinforcing jacket also includes at least one further layer longitudinally extending from the first cable end towards the second cable end for a length shorter than L. At least one layer of the reinforcing jacket is a circumferentially closed metal tube.

An anchoring assembly for securing a cable having both an optical fiber and an electrical conductor in order to provide a conductive pathway to a downhole tool. The anchoring assembly has a head and tail each having a throughbore with anchor receiving portions. An anchor with a deformable portion maybe inserted into the anchor receiving portions and the head and tail drawn together about the anchor. The anchor receiving portions have a narrowing diameter, which, upon abutment with the anchor causes the deformable portion of the anchor to deflect inward and secure a cable inserted therein. A conductive body is provided in the head or tail for coupling with the cable and providing a conductive pathway to a downhole tool.

A wire harness including: an electrical wire; and an exterior pipe through which the electrical wire is inserted, wherein the exterior pipe is provided with a plurality of discharge holes configured to outwardly discharge foreign matter that has entered between the exterior pipe and the electrical wire. An exterior pipe through which an electrical wire is to be inserted, the exterior pipe including: a body with a plurality of discharge holes configured to outwardly discharge foreign matter that has entered between the body and the electrical wire, wherein the plurality of discharge holes are provided in an aligned arrangement.

Downhole connection assemblies include a connector to receive a conductor and pin at opposite ends. The connector includes a first electrical collet, a separate second electrical collet and a sleeve. The first collet includes a first recess in a first end to receive the conductor and a second recess in a second end to receive the pin. The second collet is positioned around the pin and separated from the first collet. The sleeve is positioned around the pin, first collet and the second collet. Downhole cables include a center electrical conductor, a first insulator positioned around the center conductor, a second insulator positioned around the first insulator, and a pressure tube surrounding the second insulator. The cable further includes one or more slots extending axially along a length of the second insulator, or one or more slots extending axially along an inner diameter of the pressure tube.

A cable assembly, comprising a component, a cable, a rigid adhesive and a flexible adhesive. The cable may be coupled to the component. The rigid adhesive may be applied to cover the connection of the cable to the component. The flexible adhesive may be applied to cover the rigid adhesive. The component may comprise a ball grid array (BGA) and the cable may be coupled to the BGA. A hypodermic tubing may be applied over a portion of the rigid adhesive.
