34、ically laid wires with either the direction of lay reversed in successive layers or unilay or unidirectional lay. The direction of lay of the outer layer shall be left-hand in all cases. The strands of one or more layers shall be slightly compressed by rolling, drawing, or other means to change the

35、originally round strands to various shapes that achieve lling of some of the spaces originally present between the strands. 4.1.3.2.3 Assembly of strands 4.1.3.2.3.1 A 19-wire combination round-wire unilay stranded conductor shall be round and shall consist of a straight central wire, an inner layer

36、 of six wires of the same diameter as the central wire, and an outer layer consisting of six wires with the same diameter as the central wire alternated with six wires with a diameter of 0.732 times the diameter of the central wire. No particular assembly of the individual wires of any other strande

37、d conductor shall be required. However, simple bunching (untwisted strands) shall not be used. The length of lay of the strands in a bunch-stranded conductor twisted as a single bunch shall not be greater than as indicated in Table 3.

Rope-lay conductors with bunch-stranded or concentric-stranded members shall be either unidirectional or reversed. All unidirectional lays and the outer layer of revers

40、ed lays shall be in the left-hand direction. b) For a bunch-stranded member of a rope-lay-stranded conductor in which the members are formed into rope-stranded components that are then cabled into the nal conductor, the length of lay of the individual members within each component shall not be more

41、than 30 times the outside diameter of one of those members. c) For a concentric-stranded member of a rope-lay-stranded conductor, the length of lay of the individual strands in a member shall be81 6times the outside diameter of the member. The direction of lay of the strands in each member shall be

42、reversed in successive layers of the member.
