Belden ICONOCLAST Interconnects and Speaker Cabling

Here is the ICONOCLAST Jacket operation. They are all the same except that the TEXTILE color under the FEP is our “jacket” color. I use clear FEP as it is still UV proof, and the COLOR stays 100% the same as it is easier to die TEXTILE consistently than to dye FEP extrudeate in thin walls.

First picture is raw let-off bulk cable with the textile braid.


Next we see the clear FEP @ 750F bring extruded over the textile. LOOK at all that insulation saving HEAT from escaping.

Next we see a capstan / caterpillar take-up that PULLS the wire at a constant speed through the process so the extrusion wall is consistent.

Finally we see a take-up spool with many $$$ of cable being wound up.

Here is the TEXTILE being applied over the OFE speaker cable polarity halves, securing them tightly together for optimally consistent electrical.


Here we see the capstan pulling the process along.

This is a high speed BINDER head applying the spacer FEP thread around the “conductor” for an IC cable. It can be a 1x1 or a 1x4, the same “spacer conductor” goes into the RCA and XLR, no changes except the “core”


Here we can see the finished process, a 1x1 destine for an XLR or RCA series I IC cable.

This is the product being spooled during the operation.

The spacer conductor is run through the extruder and the proper dielectric tube wall is applied, all FEP in this case.

This is what we will have after the RCA extrusion process, and this goes into the double braiding pass.

Here is the finished RCA core being taken-up.

Great stuff! Still no decision on a Series II OFE, I take it?

Galen, what a treat to see the production process. Thanks for sharing!

Exactly what I was looking for. I dont think many realize how specialized this equipment is and how fussy it is to keep dialed in and still run at high speed.
Thanks for the photos.

Before we can start, we need to WIND evenly and with some hand control over the traverse all the bobbins!


This is the polarity weave for the series I speaker cable. 12 bonded pairs are woven.

We have RED FEP TPC insulate polarity or…

We have either the BLUE series I or II in SPTPC or OFE copper color code. The color is the price class and material. The SPTPC has a different patina than the OFE so it is easy to differentiate and we can consolidate colors and costs this way. The reel below holds OFE extrudate polarity

The SPTPC luster is shown below and is distinct to the silver under the tinted FEP.

We can manufacture one of TWO polarity designs, series I or II.

Our oldest customer makes spun paper products. You would recognize paper bag handles but they make hundreds of similar products all by an ancient process brought up to modern production standards by modern electronics but the core of the machinery is still over 100 years old. One of their more interesting products is the filler for lace trim on high end wood coffins.

Those weaving machines go all the way back to the textile industry probably before electricity was nationwide. We did some work on weaving machines like that for a sock manufacturer. To see them run is mesmerizing and they make music of their own when running in full song.

Having been to a US Steel wire mill as a kid I get it. No margin for error.

This is the series I XLR being cabled @ the Foamed FEP spacer core.

A FEP inner jacket is applied over the core after it is cabled.

We can make the series I or II, here is the series II XLR with the sixteen 30 AWG wires, four per chamber.

A copper braid is applied over the FEP belted cabled core prior to jacket.

The finished series I TPC XLR cable

Awesome stuff!

Weaving machines as in Barber-Colman?

This stuff is fascinating! Thanks, Galen, for sharing these.

I dont remember the manufacturer. It seems like there were 24 needles, 24 spools of thread, and a mechanical skip mechanism that was changed out or adjusted to change the pattern in the weave. The machines were completely mechanical with only an electric motor to run them. They had a flywheel that you would run by hand to get them moving and then engage the clutch to make them run continuously. The owner of the business was 77 years old and it was the only job he ever had. Those machines were his children. It was fun making parts for the machines that were no longer available.

Yup, B-C.

Thanks!

That is so cool. As I said most peeps dont have any idea how something like that is made. A good friend used to say that everything is simple once you get done. It’s the getting done that is hard. Also high speed processes make high speed wrecks when things go haywire.
Thanks again for posting!

It was the outer sock for these:

Termination as all hand done and VERY involved to do right. The easy step is removing the jacket…that’s it.


After that we build small air tubes out of heat shrink. We are just before silver solder here. All that work wants to FALL APART if you aren’t real careful! This is a male header.

Now we have a silver soldered male assembly, ready for the connector body.
Tubes 2
We add the inner crimp and front header to the male or female terminal body. This is a FEMALE pin header.

This is after we insert the above assembly into the metal housing and apply the rear strain relief.

The 4x4 requires SIXTEEN 30 AWG wires be managed. Here is the look at that situation!
