If this is a heating cable it implies a high current application.
That could make conductive epoxies problematical.
A crimped connector that can then be soldered might be a better alternative.
You could consider a high Bismuth alloy which will shrink on cooling,
possibly in a tube arrangement. That will give a good mechanical clamp/grip
and a gas tight bond. This type of arrangement is used for optical fibre
bonding/sealing and in some magnetic applications. (Where the magnetic
material is not solderable).
Depends on how "long term reliable" you need to be.

Subject: [TN] electrical connection question
I'm trying to make a long-term reliable connection between some Copper wires
and some Silicone jacketed Carbon stranded heating cable. An example of the
cable is at
http://www.alibaba.com/product-detail/Silicone-insulated-carbon-fiber-heatin
g-cable_863719692.html?s=p
Our customer is currently wrapping the Copper wire around the Carbon fibers,
and then applying solder to the Copper strands to enclose the "joint". This
does not seem to promise a long-term reliable connection. I am considering
some experiments with conductive epoxy and/or making some crimped tubes,
clamping the overlapping Copper and Carbon strands.
Is there any place I can find some "fatherly guidance" as I begin to explore
this territory?
Thanks,
Carl
