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.

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?
