I've heard that lead times are being affected across the board owing to increased demand due to Hurricane Harvey. Whereas one might expect a problem if they had a factory flooded, apparently a sudden increased demand is also having a significant affect. I've put out feelers to a variety of vendors. Wanted to know what this group has heard.

Much appreciated,

Mike

A sudden increased demand only from those with no spares at hand, being the consequence of company policy, if any.

We just got that message from two different transformer suppliers. They are saying they want us to identify any orders that relate to Harvey recovery so they can get priority. Not stated, but implied in that request, is that if your order is NOT related to Harvey recovery, you are the one who is going to get bumped.

I wonder how hard it would be to clean up big transformers that might have gotten wet and make them safe for reuse as opposed to having to buy new ones.
For the ones that didn't blow up, that's what's done quite a bit, but not in the field for many of them. The transformers that get serious water intrusion must be baked out for a long time at elevated temperatures and virtually no humidity, which is nearly impossible in the field.

I watched some videos of Miami taken from atop a building during the eye wall passing, it was incredible how many flashes were taking place all through the landscape from transformers blowing up.

OTOH oil filled transformers with a good vent seal should be relatively easy to clean up, yes?

Isn't likely the explosions were from conductors making contact and from expulsion fuses operating? Transformers would really have no reason to simply explode, and if they did shouldn't there be flaming oil?

For the POCO workers, that restore power, how many pole top transformers will need to be replaced?
