Fuses fuses fuses

I did a quick google search to see if places other than the USA use a different descriptor than "high breaking capacity" in their fuses. Apparently there’s also "high rupturing capacity".

Two different types of fuses.

HRC fuses are built primarily with ceramic bodies, silver plated end caps, silver internal wire and are filled with different types of powder to prevent arcing when the wire melts on one end inside the fuse. It’s also stated to be a calibrated conductor.

Sound familiar?

The stated advantages are that they do not deteriorate with age, they clear high and low fault currents and have consistent performance.

Could it be that someone just applied the better material aspects of fuse design in HRC fuses and applied them to "normal" audio fuses with the corresponding markup our hobby enjoins?

>>>>Maybe, but how did they get the 99% pure silver gold impregnated wire inside the ceramic body?

from highend electronics dot com,

"The latest development of HiFi-Tuning in Berlin is the unplated "Supreme" fuse. Even better than the predecessor "SilverStar"! The performance exceeded all expectations and the Supreme fuses became a Top Seller!

99% Silver + 1% Gold = 100% Sound
Caps and burn wire is made from a Silver/Gold alloy, even the solder (Mundorf) is Gold/Silver, and of course, like all HiFi-Tuning fuses, the "Supremes" are deep cryo treated!

HiFi-Tuning Supreme Fuses are availble in many variants - small (5x20mm), large (6.3x32mm), fast blow (F) and slow blow (T) and the price is $59.95 for the small Supreme and $89.95 for the large Supreme."

This just in, from Parts Connection,

"HiFi-Tuning of Berlin-Germany has released a new highest performing version of their industry-leading fuses called "Supreme".

The new line of Supreme fuses is handmade, tip-to-tip of 99% Silver combined with 1% 24k Gold, similar to the material used in the Mundorf Supreme Silver/Gold Capacitors.

Mundorf also developed for HiFi-Tuning a special Silver/Gold solder for use in the Supreme fuses.

HiFi-Tuning's 99% Silver + 1% Gold melt wire, used exclusively in the Supreme fuses, is resonance-optimized to control vibration.

Technical: To understand the advantage of the 99% Silver + 1% Gold combination, think about silver's crystalline structure. The drawing process for silver (or copper) wire causes micro cracks in the surface of the wire. The cooling process also results in imperfect crystal grid structures. Both of these "deformities," relative to the ideal of a perfect conductor, result in surface distortion when current flows through the wire. The addition of 24K gold fills the micro cracks and the empty spaces between the crystal boundaries to improve transmission properties, while also inhibiting the surface oxidation and tarnishing that will occur over time otherwise."

The underpinning is that a ’fact’ is a name, a moniker, a logic misnomer... for a highly predicable theory. But it remains theory.

The use of the word ’law’ in science is also an attempt to put social and cultural group pressure on individuals to conform or be punished by the group. At least this is part of the traditional meaning of the use of the word law. Thus we can see the the word law remains as being in the world of human social/cultural structure and in the supposed world of logic, has zero place in the world of science.

So we can have the word law in the world of science, if we are looking to prosecute people and possibly kill, ostracize or beat them to death, in public, for ’violating’ laws. Which, according to the tenants of science, is patently absurd and against the very fabric of science and what it is supposed to stand for.

But the word works very well in religion. Is science with laws -- a form of dogmatism?

> Let me guess. You’re an English major? A Drama major? A Religion major? But seriously, it is not really too difficult to demonstrate to anyone that the world is flat, that the speed of light in constant in the universe, or that there are black holes in the center of most galaxies, including ours. Of course if one’s mind is closed it makes it more difficult. It is also fairly easy to show that there was (almost certainly) a Big Bang, that the universe is around 14 billion years old, that the universe is expanding, that there are gravity waves from colliding black holes, There are such things as truths and facts in science. Why pretend there aren’t. Are you trying to be Juror #10? "You can’t prove it!" Man discovers or uncovers reality of the world and universe around him by observing, theorizing, experimenting, by mathematical or experimental proof and/or by weighing the preponderance of evidence. And by establishing Laws and theories that he believes govern phyically reality. Some theories like atomic theory is evolutionary in the sense it is ever getting more complete and more complex.

Thank you for putting the word belief in there. Truths and facts exist for engineers and engineers alone. Well, for them and the religious, anyway.

No scientist would ever use facts, they have only theories. Go ahead, ask someone with a doctorate in any of the fields of physics, whether there are any laws and facts in science.

You will get a strong no from all of them. If you get a yes, then be assured, you are talking with an extreme minority. If you talk with a university professor in the realm of physics, you will also find out that they don’t teach facts or laws, they teach theory, and theory alone. For all the right reasons. When talking to the average person they might go for facts and laws, but when dealing with the new or exploring the new, everything reverts to the theory aspect.

When you start to play with the edges of proof and conceptual aspects, like with this subject of fuses and whatnot, things get complex and facts and laws have a long history of getting in the way (when we play in the rarefied reaches of the known). Thus, they revert to theory, which is what they really are.

I’m trying to make it abundantly clear that only theories exist, and there are no facts and laws. And that -- is the underlying force behind reason and exploration in science. It is absolutely critical that exploration go forward under such a mindset, a mindset that is not kneecapped by facts and laws before it even takes a step. All of science in it’s exploration agrees with this, even if you rarely hear them say it.

Teo, why pick me to become unhinged on? I don’t get it. If you want to get into some weird pseudo philosophical argument with me you’re barking up the wrong tree. Fortunately the world is not as complex, unfathomable, opaque, impenetrable, mysterious, theoretical or uncertain as you portray it to be.

only an idiot would claim there are no facts
