The best isolation material ever made. Originally invented for space applications. Self cleaning and antistatic. It will not attract dust and acid particles from the air. Teflon has all you need, like: extremely voltage resistant, flame resistant, non-aging, mechanically strong and still easy to work with. Ideal for making cables and isolators. |
|
|
This material has higher
isolation properties than Teflon, but it is too soft. You can make
a 2500 Volt cable with it, but it feels like soft rubber, and
it is difficult to mount nice. When there is pressure one point,
or when bending over a sharp edge, the cable will damage easily.
Just silicone isolated cable is definitely not recommended for DIY.
To make it possible to use it, we have made a special cable with
very tight cotton cloth around it, which makes the cable stiff and strong,
and easy to mount nicely. Now it becomes the perfect cable
for all High Voltage lines in your amplifier. It is only available
in red.

One of the lowest resistance
conductors, with ideal contact properties. Used in transformers and
cables for the superior sound. Silver is a relatively stiff material,
and for cables that need to flex, a Litz wire must be used.
Silver is stiffer than copper, and a silver Litz cables feels a bit like a solid cable. So when you bend it, it stays in that form. When you bend it back, the cable is not untidy, and looks like it was never bend before. This is nice about silver, and it is very nice when wiring the inside of amplifiers. Note, that for this reason the High Flex signal cable can not be made of solid silver Litz, but must be made from silver plated Litz The normal silver Litz cables have an ultra thin copper core, for the same reason, but the silver content is still 75%. If you take out one single wire of the silver Litz, and hold it in a flame, you will see the silver melt, and it forms drops, hanging on the thin copper core. You need a lens to see this, and it is proves the purity of the silver. I will try to make a picture of this, and place it here. |

ISOLATION |
Just look into really
old equipment, and you'll see all wires have aged. It can age a lot, and
in the end make the equipment useless, because of leakage or short circuit
risk. For most applications the aging won't be
a problem, but for High Voltage applications it is. High voltages
will slowly degrade the quality of the wire, and attract a layer of dirt
on the wire. This layer can be hardly visible, but consists of aggressive
materials, holding acids in a dust-powdered form. So, before
just putting any wire in your tube amplifier, check the rated working voltage.
You will see a 600V DC wire is either very thick, or hard to get.
If the wire is under mechanical pressure, has a sharp bend, or contact
to hot components, the cotton will give strong mechanical protection
to the inside, and prevent isolation damage. This is because we have
it woven very stiff. Besides... it looks really nice.
Today's DIY prefer these cables for the fine looks. We
have it in several ancient colors. Like: dark green, dark blue,
ivory white, navy blue. Etc. It looks just like vintage cable.

For using Litz cables
are a few reasons: 1) A multi stranded cable (Litz) has better high
frequency properties, due to the skin effect, where electrons travel along
the skin of the wire. A Litz cable has a higher surface, and for that reason
will give better conductance at high frequencies. It is a "must"
in high frequency technology, but many Audio experts prefer Litz
wire also. 2) It will not break easy, when flexed very often.
For very thick cables, only an ultra fine copper Litz will make that the cable is highly flexible still. So Litz number of 400...800 should be used. |

All our electronic components
are stored in a climatized rooms. We use electric equipment to filter
and dry the air. This keeps all materials clean and oxide free.
So what you receive is bright and shiny, new condition. (Read

High
Flex cable, silver plated
Very high Quality, SILVER plated Litz wire, with TEFLON isolation. Total diameter 1.3 mm This wire is ideal for making your own silver wired phono cables, or can be used inside amplifiers as the perfect signal cable. The silver surface is untreated. It is shiny white when you take off the Teflon. It solders excellent, and the Teflon will withstand any soldering heat, no matter how long you solder. The Teflon is flexible, but very strong material, and will not be cut nice with a normal isolator tool. It's best if you use a very fine knife, or a razor blade, for isolating it. Attention: to get the high flex properties, only a thick silver plating is possible, solid silver Litz will be too hard. So this Litz is silver plated. Rated Power: Only for small signal.

0.8mm / AWG 20. Solid Silver + DOUBLE Cotton cloth outside 99,99% pure solid silver core, soft outglowed.
Make your own silver speaker cable with this! Solid Silver Wire, with a solid 0,8mm /AWG20 silver core, soft outglowed. All colors we use, are from the color chart, and are choosen like the colors you see in old radios. This cable is double isolated, and the resulting cotton isolation is very strong, and will not damage when you walk over the cable. Application: For speaker wires. You can use it single wired, or twist a double wire. When you twist it, order 5% more length because you loose this from twisting. How to twist? Before you start, straighten the cable mostly. No need for perfection when straigtening it, but of course it should be no mess before you start. Take an electric drill, and while pulling the drill back with reasonable force, start twisting the cable. Go on until you notice suddenly the cable starts to get shorter much quicker than in the beginning. You can't oversee this moment, it happens suddenly, and you can see it and feel it. When you stop now, you have lost about 7%. Don't take it out of the dril, but pull the cable firmly, so it straightens, and while doing so, rotate the drill in the other direction. From this the cable gets longer again. Stop at a length loss of 5% or at any point where you think it looks nice. When you stop now, the cable will be tension free, have a very profesional "feel" and is as nice as any ready bought silver cable! If you have no drill, you can also use just a small stick, and rotate the cable with that by hand. Just takes you longer. With the 0.4mm cable you can also make nice speaker cables, but you need more wires then. For this, drill groups of 3...5 wires together, and then drill those groups these together in the opposite direction. That gives a nice, tension free, flexible cable. Good luck with it! As said before.... You can also use a single 0.8mm silver wire. Up to 2 meters that is fine also. Ordering code:

99,99% pure solid silver core, soft outglowed.
This is Solid Silver Wire, without isolation. It is specified as 4N, which means "four times nine", or 99,99% pure. It can be used for wiring loudspeaker cabinets, or for free wiring in amplifiers. This wire is made on special requirement for us. It is a wire of very high purity, which was reached by using a very pure silver bar to begin with, and a sapphire tool for wire pulling. This is resulting in a very clean and shiny surface. The wire is medium-soft, by means of a re-heating cycle after wire pulling. Storage: All our electronic components are stored in a climatized rooms. We use electric equipment to filter and dry the air. This keeps all materials clean and oxide free. So what you receive is bright and shiny, as new made. (Read more...) Possible Applications:

Note: Same way as AUDION UK does in their beautiful made amplifiers. With this wire a ground path is made (20cm length). All grounded components are now connected to this path. The silver wire is grounded at one end only, at the Audio Input connector. Ideal way to prevent hum, and get a "virtual star" grounding with having to wire a "star". This can only be done with a very thick and low resistance wire, like 2mm silver. The resistance of silver is lower than copper. | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||

Some examples of custom made cables |
Speaker cable, of pure silver Litz Wire / 99,99% pure silver We make this for you, from 0.4mm wire. At a length of maximum 10 meter. You can specify the number Litz wires yourself. The cost is 1.5x the cost of the bare silver wire that is used, or 1.25 when you choose the cotton isolated litz strands. Like this, a silver cable will cost you only a fraction of what others charges you for it! As isolation, a woven PVC sleeve can be used, or you can use your own isolation yourself. Also it is possible to twist the wires. Here is an example for a High Quality Speaker cable of 21x Red Cotton Litz and 21x White cotton Litz. So this cable has one red and one white wire. Each single strand is cotton isolated, for lowest Skin effect. Note, skin effect for Audio purpose is lowest at 0.4mm. This is why we choose this diameter.
Just FYI, here are some links to very good companies, offering very nice silver cable products too. http://www.audionote.co.uk
As isolation, a woven sleeve can be supplied, or you can use other isolation material of your own choice. Some calculated examples of custom made cables

How this cable is terminated |
Speaker Cable, 2x 800 Litz, 2x isolated + flat cable cover layer This is superb quality! Inside this cable is one red and one white wire, each 800x Litz Each wire is twice isolated, and the outside layer is of 100% cotton. Then, both cables together are in a third layer, making a flat cable out of it. So it is not just put into a sleeve, but the outside layer is actually woven around the cable, so you have an elegant, and still thick flat cable. So, inside isolation is always of cotton, the outside layer is available in cotton or antistatic PVC. The cotton is very thick and is perfect for normal use. The PVC is heavy duty, and is ideal for applications where people walk with their shoes over the cable, or similar (Like in HiFi shops). The PVC is still looking very High-End also, and can be used for home applications just as well. (Note, this is the same PVC cover as used with the shielded Mains cable) All cotton colors we use are "vintage" so we use ivory-white and dark red, and brown-black. The cable has an effective diameter of 10mm2 per wire, or ~AWG7. Each wire consists of 800(!) Litz wires. So you can imagine how fine it is. For Termination, the FURUTECH connectors are ideal. They are top-quality from Japan. These can easily take the diameter of this cable. Rated Power: Max 1600W continuos @ 8 Ohm. Resistance: 0,0032 Ohms per meter for both leads together. So one lead is 0,0016 ohms per meter. Weight: 275 gram per meter Ordering code:

Mains cable This cable can be used to make very high quality mains cables yourself. This cable has a cotton sleeve already factory made around the cable. To keep the cable flexible it needs to have a round shape, and the outside cotton may not be applied too stiff. To make this possible, the cables has several cotton fillings. When using this cable, you will be surprised about how pleasant this cable is to work with. Many times better than the stiff cable that is used as a standard product with 99% of expensive equipment. It is intended as mains cable, but can also be used for making the mains wiring inside ten chassis. Ordering code:

Mains cable with RFI shielding. This cable can be used together with the FURUTECH mains connectors. It has following features:
Amazingly good results for shielded
mains cable have been reported by many people!
Best use: The ground wire must be connected
the normal way, as with any three wire mains cable. The RFI
shield must only be connected at the chassis side. So, no current
will flow through the shield. Like this the shield has only
a static function, and it will be a Faraday cage all around the mains cable.
No radiation can go in or out a Faraday cage... as long as no current is
flowing through it. That is why the shield must be connected
to the equipment chassis only, and to nothing else. Any 50Hz (or
60Hz) radiation from the mains cable is now most effectively suppressed,
and can not interfere any more with sensitive equipment. The more
unshielded cables, and the longer they are, the stronger the overall signal
pollution is going to be. So you must try to avoid spaghetti of unshielded
cables behind your equipment. Better use shielded cable.
For best results, it is recommended
to replace all mains equipment cables of the complete stereo installation
by shielded mains cable. You will have only good results with
professional material. 220Volt and also 110Volt is a
very high voltage, and not possible to shield with little efforts.
You need a good quality, thick and good conducting shield. Some cables
are sold, with just some industrial safety shield around it. This
is NOT what you need, and besides these are very stiff.
You need good RFI shielding, which is more expensive material.
Because of the high diameter of shielded cable, and for getting normal
use comfort, a high flexibility cable must be used.

Solid
Silver Solder. Large 100 gram roll.
This is not pure silver, but an alloy, and you can solder this just with a normal solder iron. You do need the special flux that we sell also. This is a liquid flux, also excellent for Litz wires. Good silver soldering takes practice, but it is easy to learn. For best results take a lot of flux, and add more flux when you re-solder. Remember that with silver solder, the flux will start to function when it gets burned by the heat of the soldering iron. So take a higher temperature,and it will flow good. The burned flux can be removed later with alcohol, or other solvents like acetone or nitro. It will solve in almost anything, just not in water. Use a small, hard brush to remove the flux. Silver soldered joints will be bright and shiny, and look much better than normal solder. They are mechanically stronger, and is harder than normal solder. Highly recommended for soldering silver wires, which are just mounted "loose" in Speaker cabinets. Silver conductor wires are harder material than copper, and this means the mechanical load on the solder joint is much higher than you expect. After some years, bad contacts may come when thick (>1mm) silver conductors are soldered with too soft solder. This is not recommended. So, use silver solder for silver wires thicker than 1mm. Also, this silver solder will not give "cold" soldering joints so easily. Hint: For clean desoldering we sell an excellent, and low cost desoldering iron. (Check under "tools" in the menu) |

AWG means American Wire Gauge, and is a method to categorize
wire size by a "number" instead of diameter.
As the word AWG says it is for America only. In America the AWG system was designed logarithmic, because that makes things easier. For normal electricians (like me) there is still the option to look at the wire diameter of course. Here is how AWG works: By lowering the AWG number with a factory THREE, you lower the wire resistance with a factory TWO. You can just hold on to this. Also it means that the step from AWG2 to AWG1 is the same size as the step from AWG33 to AGW32. One Step is roughly 26% change in resistance, regardless at what AWG number you are, and regardless if you go up or down. This a nice system, when you want to know how to quickly change the resistance of the used wire by 26%, by just changing the AWG one number. When you want to know anything else, no matter what, calculating that from AWG can drive you crazy. So here is a conversion table. |
