heavy rainfall underground cabling
(OP)
I have recentley contracted with a Costa Rican electrical firm for underground install. 240v/ 125amp per pvc conduit/ from 75kw trans. concrete boxes w/metal covers. #000 shielded aluminum. some boxes are not drainage prepared. Some cables are longer than others. Some runs are 300+ meters. Yesterday they placed foam filler at the ends of all conduit tubes. also the possibility that water may have entered some conduit during install may have occured. What suggestions do I give my installer to stabilize this situation. What other info can I provide. Why are these issues important.

The recepie for bitumen closing is: heat bitumen in tuna can (cylinder shaped any shop :) ) and just put the end of a cable in it. Bitumen is easy to heat and will cool down easily and fast. after this is done you will have good protection from moisture in cable until installation. This may sound funny to someone, but I saw that recepie in many countries all around the world and cable jointer's are all agree it is best and cheapest way of finishing such job.
