Coloured Wires On Power Poles!

There's an area where they are upgrading the power lines there's the primary ones (115kv according to one of the guys on GOL), and a smaller/lower-voltage as well.

The lines you see here aren't the primary ones which are up a fair bit higher - near the top of the poles (and are just the normal silver).

But take a look at these lower-down ones, and note that the 4 are each a different colour! Blue, Red, Yellow, Green.
Also note how the wires each have a wheel where they are attached to the pole...that's so they can feed wire from a giant spool along the poles.(I would love to see that operation in progress!)
This is something I have never seen before...

Nah, those are pencil laces. It's connected to a big sweet factory. They go through the air to cool down toward the cutting/packing building. You got apple, banana, strawberry and blueberry going over there. I'd imagine the inner core would be very sour and your tongue'd get a mighty zap! Razz

it is very important to know what phases is what. last thing you need. getting your phases mix up can make 3 phase motor turn wrong way.

There are so many places downstream where this could be confused, you gotta check yourself anytime you are connecting a motor and correct if needed. As for the power company swapping the phase order for a whole district in a power line upgrade, this is quite unlikely as long as they don't change the positions of the wires on the pole arm vs. how they were before, and test the order at the feed for this line with the appropriate instrument

Yeh this is similar to what they did at mine on the HV are you sure itâ€™s not 11.5 KV

The isolators look tiny for 11.5kV. They would hold the voltage, but possibly flash often when they get dirty and wet

LOL lasagafield!!

Yep, you deff wouldn't want to get the phases mixed up Shocked

@Kev:
The guy on GOL said he'd talked to the power-company guys who were out working on the lines at one point .. the upper/main HV lines are an upgrade from 45kv to 115kv (I'll post a pic of those & the huge insulators)

those insulators now days are rated at 25 Kv. a have seen some nasty flash over about year worth grimmy dust stick to them then this light rain hits catching the poles on fire.
