A significantly lower factor probably means it has water in it.


Roy-

Is this correct? As described, the "dielectric" is mostly air with some
plastic used as a spacer. I would have expected something over 90%.

I was going by the manufacturer's specifications. I've never used this
stuff myself. I think if you look at the construction you'll find more
plastic and less air than you might expect.

Back to the question of how to get the water out. If there is a large
quantity, you might be able to pour it out. Beyond that, is there a
common technique used to dry-out cable? (I suppose a shop-vac could be
connected to one end and run for a while, on a day with low humidity.)

Hopefully someone else can help you there.
