Have I mentioned how much I hate aluminum wound preheat ballasts?

Have I mentioned how much I hate aluminum wound preheat ballasts?

Click to view full size image

This fixture was on for only three hours in my home. It had cheap Chinese BENBON aluminum winding wound preheat ballasts for 36 watt tubes. I started smelling some weird smells so I tracked it down to this fixture. I touched it and it was really hot (the body of the fixture) so I unmounted the fixture and guess what? the ballasts got so DAMN hot they MELTED the plastic body!!!!!!!! I HATE ALUMINUM WIRE PREHEAT BALLASTS. I ripped them out and thrown them out, the bloody things are a real fire hazard! I swear to god those Chinese companies get away with anything, this is really dangerous.

Wow!

Good quality things are awesome. Cheaply made things are not.

Wow!

I know right? This is pathetic. One day someone can die in a fire caused by these cheap abominations of a ballast.

New lighting technologies is a pity fest everywhere you look. From LEDs that last only for two months, to a never-ending global starvation of t8 fluorescent tubes.
We shall reinforce ourselves with good old full mercury t12s and HIDs made to surpass one's life, and give them all the middle finger ;

At one time (about 10 years ago), several cheap weather packs were withdrawn from sale in Finland, reason was melting in EOL lamp situation. But now it happens already in normal use...

Some old Finnish Helvar made MV ballasts also use aluminium wire. They have already worked over 40 years.

Soviet ballasts used aluminum wires in them. And there is literally nothing wrong with aluminum wire if it is thick enough and there are extra winding than needed to accommodate the higher resistance of aluminum. I have a 1961 soviet f80t12 ballast that has two separate f40 aluminum wound ballasts inside connected in parallel, both sunken in tar. And it worked great for 50 years. Being cooked to perfection with eol tubes in school that I got it from and it still runs almost quiet and cool to the touch with my Philips actinic 2ft f40t12 tubes. There is absolutely no problem with aluminum, but you POSITIVELY CAN NOT SKIMP ON IT DURING MANUFACTURING or else the final product will reach 200'C temperatures and will melt everything not made from metal and will burn everything it touches.

I bet the Chinese copied a standard choke design that used copper wiring, without changing the dimensions of the core and windings to account for the decreased conductivity and therefore higher losses. They changed the material to make it cheaper, but they didn’t adjust for it in the math, probably because they didn’t care since it means they can save even more material and make more money, with no regard to the fire hazard it creates.

I have heard that the aluminum wire should be twice thicker than the copper wire.

Aluminum has around 60% of the conductivity of copper, so that approximation would work, but would be a tad excessive. The real issue is that the dimensions of the winding would be much thicker, causing the core to have different dimensions, and so all of the math for the inductance of the choke would need to be recalculated (basically, you would be designing a new choke), and I doubt the chinese actually do that, since they have a history of copying things without understanding how they work, leading to the creation of some poorly made abominations.

关于铝线镇流器,在我们中国的电器电子爱好者论坛里,被讨伐过不知道多少次了,那些奸商牠们全家火葬场了!

我不会英文,所以我用中文,请你们用翻译网站翻译我打的字!

I can't in English, so I in Chinese, please use the translation website to translate my words!
