OPTICAL FIBER COATING TO REDUCE FRICTION AND STATIC CHARGE

摘要

A system for making an armoured cable, comprising:
a tube-forming device (114) configured to seam weld an armour tubing of the armoured cable;
at least one guide tube (108) disposed in a welding zone (110) in which a seam of the armour tubing is welded, the at least one guide tube positioned to protect at least one optical fibre (102) during welding of the seam, but is not part of the armoured cable after the making; and
a coating device (116) configured to coat the at least one optical fibre with a coating, wherein the coating is configured to reduce friction between the at least one optical fibre and the at least one guide tube during an insertion operation.
The present disclosure also includes a method for making an armoured cable.
