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 10 impermeable to the fluid in the cable. For cables having more than one conductor, an additional elastomeric boot is installed over the cable.
