Subsea pipeline direct electric heating cable with a protection system
摘要:
The present invention relates to a piggyback cable (10) comprising a copper conductor (2) with a standard triple extruded insulation system including a conductor screen (13), an insulation layer (14), and an insulation screen (15), an inner sheath (16) surrounding this insulation system, and an outer sheath (18), the space between the inner (16) and outer (18) sheaths being filled with protective elements. The main technical feature of a piggyback cable according to the invention is that the protective elements comprise thermoplastic (21) elements arranged together to form at least one layer helically wound around the said cable (10).
