Connection for heating cable |
(57) The present invention relates to electrical heating cables and in particular to provision
of an improved heating cable conductor joint, - prior to application of common outer
sheaths over the conductors and the joints. Such joint includes butt-jointing end
portions of two electrical conductors having different diameters, in particular for
jointing a heating cable resistance conductor to a cold end copper conductor and vice
versa.
The invention includes reducing the diameter of the end portion (3) of the larger
conductor (2) before abutting the ends (1,3) of the two conductors and jointing the
two conductor ends. The diameter should be reduced so that the diameter over a crimp
jointing element (4) crimped over the conductor ends does not exceed the diameter
of the larger conductor.
