They're a Huge Korean conglomerate, making all kinds of stuff.
They make the coolest looking ATM ever.
My personal dealings with them are in the pic below. I installed 8 of these in Arkansas and 4 in Louisanna. They were preferred by the Customer, Entergy, due to cost.
They're HICO 500kV to 230kv single phase autotransformers capable of 760,000,000 VA.
They bank three of them to make a three phase transformer, used at points in the grid where a system voltage change is required. Each one holds around 15,000 gallons of oil.
They were around $1,200,000 each as delivered in crates.
In appearance they are incredibly rugged and "overdone" kind of like 1950'-1960's Russian technology. Rugged but obsolete from the get go.
Like the bikes they appear to be reverse engineered without a complete understanding of the "why" behind certain design elements.
Every single one of them has had excessive weld leaks, oil coming straight through the seam welds at various places on the main tanks.
Total crap and hope I never see one again.
I would never buy one thier bikes, I've looked at a couple on the showroom floor and they too, like the transformers, appear primitive in the design and material details, and poorly executed in the assembly.
I don't think they're garbage either tho. Seem to be about where the Jap bikes were in the 60's.
Remember when Kia and Hyundai were total crap?
Watch out one of these days Hyosung will figure it out too.
