110 v site transformer repair ?

[Rufus2502]

I was given a couple of 3 kva site transformers, both have broken bases and all the sand has leaked out, epoxying a new base on is no problem, and I will only be using them myself at home, but what kind of sand should I refill them with ?

Chuck them in the bin and buy a new one, they are very cheap these days, why bother with tatty old carp?

you need sand from Bondi Beach ( Australia ) as upside down sand is the only type of sand that will stop anti-clockwise EMF causing premature escape of the electricity in the secondary, because the secondary is centre tapped to northern hemisphere earth.

Builders sand.

Block paving joint filling sand, it's dry and fine.

Whether it's fine to refill a damaged TX is another thing.
