Abstract:
A method for forming a longitudinally water-tight section in a predetermined area of a multi-conductor wiring system, the multi-conductor wiring system having a plurality of individual conductors, each individual conductor being encased in an insulative sheath, the method comprising the steps of:providing an adherent tape having a single sealing compound for adhering the individual conductors thereto and for sealing spaces between the individual conductors when exposed to a softening temperature less than the softening temperature of the insulative sheathes of the individual conductors, wherein the sealing compound is Butyl rubber in which the individual conductors adhere at room temperature and said Butyl rubber having a softening temperature of approximately 60.degree. C.;arranging the individual conductors parallel to one another in a direction transverse to the adherent tape in the predetermined area on a first end of the adherent tape;folding a second end of said adherent tape onto the conductors such that the individual conductors are sandwiched therebetween;pressing the first and second ends of the adherent tape together to sealingly fill the spaces between the conductors;applying an outer envelope over the sealed predetermined area; andcompressing the sealing compound and the outer envelope at an elevated pressure while said sealing compound is heated to the softening temperature such that voids, pores, and gases in the sealing compound are substantially removed.
