Hello brn,
OK, I believe this to be a horizontal thermoplastic or moisture cure (Sioplas) extrusion line. (Please try to always provide full information with your questions in future. Thank you.)
1) - I have seen the following procedure successfully done many, many times:
1A) - The outside end of the new cable is prepared by the sheathing operator in advance as follows:
The outer layers of the cable core are cut away and the inner layers are made to form a loop. The overlapped insulated wires at the end of the loop are then very tightly bound with bare copper wire.
1B) - The inside end of the cable presently being sheathed is similarly prepared once available to the operator however:
The prepared end is first looped through the already prepared loop on the outside end of the new cable.
Then the complete splice is wrapped with sticky tape so that it is waterproof. The overall diameter of the splice is smaller in diameter than the core so that the splice can be easily found once it passes through the extrusion line.
2) - Another method is to use two reusable Hubbell Kellems grips and as before some of the outer layers of the cable core are cut away.
See
www.hubbell-wiring.com/htm/catalogindex.htm then go to page 638 in the catalog. The data starts on page 639 and you can review this all yourself. You tighten the grips on the remaining core with punch-loc bands (page 650)
As before the complete splice is wrapped with sticky tape so that it is waterproof. The overall diameter of the splice is smaller in diameter than the core so that the splice can be easily found once it passes through the extrusion line.
You will need an inventory of Hubbell Kellems grips and disposable punch-loc bands for this purpose.
