Flexible Conductor Jointing

For the flexible conductor Class-5 or Class-6, what is the best method of jointing. Joint is not for electrical conductivity rather for continuous processing during extrusion. Is it welding or crimp or tying ?? please suggest the best method. :)

Hello,

From my perspective, I think welding, with a ceramic guide tube, is by far the best method for making a temporary splice at insulating. The splice of course has to be cut out after insulating regardless of which temporary splicing method is used.

The reason for my selection is the small clearance in the bore of the extruder tip (nipple).

If you tie or crimp, you have to remove some of the strands to make sure the splice can get through the the tip. This means that one needs to solder the overall strand at some short distance away from the end. Then one must carefully cut away some of the strands so those cut ends do not jam in the tip. It also takes time that you may not have.

Thank you very much.. :) the method you recommended should be good for smaller cross-section conductors (upto 16sqmm?). I doubt whether it will work for bigger conductors aswell? May be a welding machine supplier can suggest.

Hello again,

This procedure works for large conductors as well and is used by many wire and cable companies with large CV lines.

A place to start would be AUGUST STRECKER GmbH & Co. KG www.strecker-limburg.de/de/ I suggest you contact them by fax or phone because they don't seem to respond quickly to E-mails.
