Patent number: 7973241Abstract: A pressure restraining enclosure for cables can include, for example, a first cable including a conductor and an oil-containing layer surrounding the conductor, and a second cable having a conductor. A splice can connect the conductor of the first cable with the conductor of the second cable. A pressure restraining sleeve can overly the splice and the conductors of the first and second cables. Several fasteners can be applied to several locations on the pressure restraining sleeve to tighten the pressure restraining sleeve around the splice and portions of the first and second cable. Embodiments of the pressure restraining enclosure can be used in the form of a sleeve on a single core cable, or alternatively as a body and a separate sleeve on multiple core cables such as three-core cables.Type: GrantFiled: September 10, 2007Date of Patent: July 5, 2011Assignee: 3M Innovative Properties CompanyInventors: Christopher J.

Patent number: 7635813Abstract: A cable has a conductor extending therefrom and a partially exposed fluid-containing layer surrounding the conductor. A connector is joined to an end of the conductor, and an electrically insulative, elastomeric tube is covers all of the exposed fluid-containing layer and a portion of the connector. The elastomeric tube is substantially impermeable to the fluid in the cable. For cables having more than one conductor, an additional elastomeric boot is installed over the cable.Type: GrantFiled: September 10, 2007Date of Patent: December 22, 2009Assignee: 3M Innovative Properties CompanyInventors: William L.
