Underground S.W.A. Joint.

Q.1. Why not just overlap the steel wire armour strands and connect them with a big connector like the live cores?


Q.2. Why not provide an air vent hole to let the air out that would aid the filling process. After use the air vent hole could be capped off with a push fit cap.

    In my experience, the job is much more difficult if one tries to do much with the armour, it is very stiff (particularly in larger cables) and there is a lot of cross-section to join which is difficult. If the joining is just the cores it is not bad, and can be quite compact. The link braid and springs seem to work, and more importantly stay working when encapsulated. I don't think I have ever had trouble getting the resin in, if you do just work a bit more slowly, the air bubbles do take time to come up and it is important that they all have.
