I think he might have left something out?

He didn't clean the cable, sand it, or take off his dirty gloves while preparing cable. also he didn't seal the neutrals from water migration...

Steve those are parallel runs of the same phase, neutrals are tied together and brought down to the counterpoise. As are the other two phases. Neuts are almost always derated in a utility because you have a parallel path with the other two phases neutrals as well as the earth.

I am just learning and practicing cable splicing and terminating power cables at work now, and I gotta agree with JW Splicer... watching him do the term in his gloves the entire time then not even clean the cable at all.... just wrong. Maybe he cleaned it and it's just not in the video, who knows, but that's a pretty critical step...far from a complete how to video if you ask me. Icing on the cake is when he torques the lug down with the impact gun.

How long do you that connection will last? :laughing:


Id argue its not so bad as an elbow, but still. Those connections can develop corona which might take years till something happens. Also, do over head stress cones need a drain wire like elbows do?

Oh ok! Gotcha! No only semiconductive premolded rubber terminations and splices need the drain wire... i.e. 200A loadbreak and deadbreak elbows, 600A T bodies and receptacles and some OLD ugly pre molded rubber stress cones... If it's tape or shrink technology there won't be a drain wire. The higher the voltage, the more important it is to stay clean and nick/sweat/blood/dirt free. Although failure can and often does occur at lower voltages. I've seen some complete crap that has been in and packing for 40-50 years...

Transmission cable is completely unforgiving and a failure will likely wreck your career... Or so they say (that's all through word of mouth)

Hey those look familiar,,no die electric grease?? Don't have to sand anymore according to manufacturer depending on the cable.would rather have you grease it good. I put two layers of mastic down at the base when I have concentric neutrals., and I was always taught to scotchbrite the pad, then dip your wire brush in no-Ox then rub it on with the brush. And can't believe he didn't torque them and that he used the impact.
