Guys, With my recent work with jointing Underground cables, I have found that the S-A tape is less than what it used to be, adhesion-wise. I'm not willing to name brands here, but one of the more prevalent brands do thier manufacturing in Brazil. We have 1/2", 1" and 1 1/2" tapes here for HV work. But the quality is just not the same. What do you guys think?. Maybe it is just me!.
I myself can't really comment on what s/a tape used to be but as an airfield electrician i carry out jointing underground also, with kits that previously incorperated uninsulated barrel crimps a patch of s/a and an outer heat shrink to through joint the 6mm2 double insulated cables used on airfields through out the country.In the last 3 years for some reason have done away with the s/a patch and included a small inner heat shrink!!!! i don't know why this is but personaly i would prefare the patch, inner and outer heat shrink
