11 kV S.W.E.R. output side of transformer. Note the front bushing is shorter and that is the Earth side of the S.W.E.R. line:




Overall structure of the 50 kVA transformer. This is on the Kopu to Coroglen rd, Coromandel, New Zealand, about halfway on a 23 km's metal shingle road, I had to convince my misses and children to take this road which is rather dusty and bumpy:



better view of the Earth bushing on the right hand front side of TF:



View from the S.W.E.R. out-put side:

Metal shingle road? What the heck is that, Ray? Same as what we would call a 'washboard' dirt road cut by a grader with a bouncing blade?

I think washboards are also sometimes caused by slipping differentials. I've seen roads where on curves there was a washboard under one tire but not the other. On the straight sections, no washboard at all. Then again, I know sometimes they are caused by the grader.

Correct Radar

We call these roads here metal or shingle roads.
They sometimes do get called wash board roads too because of the bumpy corners.
Graders roughen up the surface once in a while.
I think the channels are caused by run off from rain water, following the camber of the road if any, otherwise potholes appear.

Interesting yaktx, I have never thought of that but I think you are quite right there, thanks, I learned something new today about the "SWER" roads.

Ahh yes Ray,
The shingle road.
I learned to drive on them and they seem to be a thing that a lot of tourists here have a hard time negotiating, especially if they've just been graded.
The key is to keep your speed down and don't make any sudden movements with the steering wheel.
Keeping your wheels in the two un-shingled paths, will keep you from going into the shingled mounds either side of these paths.
Striking these at speed can cause serious "fish-tailing" and consequent loss of control of the vehicle.
I nearly rolled a Fire Service tanker carrying 5000 litres of water on a road like this one night, it is not an experience I'll ever forget.
