The cable (1) structure, without a covering, has shaped wire strands (2) at intervals round a plastics core (3). The strands (2) have a trapezoid cross section, with an air space (4) between them The cable uses six to eight strands (2), and pref. six, with a trapezoid cross section. The inner core (3) has a round cross section, with parts of its material forced outwards between the strands (2) through the cable twisting action, forming the air gaps (4) between the strands (2). Spacers can be inserted radially inwards into the air gaps (4) between the strands (2), as tensioners or support strands of a compact plastics or processed plastics fibers. The trapezoid wire strands (2) are compacted, with core inserts of compacted plastics or processed plastics fibers. The strands (2) can contain metal cores. The cable core (3) can have a softer outer plastics material than its center section. |
