33、sed 4.1.3.2.2.1 A compressed-stranded conductor shall be a round conductor consisting of a central core surrounded by one or more layers of helically 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 sha

34、ll 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 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

35、.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 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

36、 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 stranded 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

37、 twisted as a single bunch shall not be greater than as indicated in Table 3. The direction of lay of the strands in a bunch-stranded conductor shall be left-hand. 4.1.3.2.4 Length and direction of lay 4.1.3.2.4.1 Every stranded conductor other than a bunch-stranded conductor twisted as a single bun

Rope-lay conductors with

39、bunch-stranded or concentric-stranded members shall be either unidirectional or reversed. All unidirectional lays and the outer layer of reversed 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-strand

40、ed components that are then cabled into the nal conductor, the length of lay of the individual members within each component shall not be more 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 in

41、dividual 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 reversed in successive layers of the member.

42、DUCTION OR DISTRIBUTION WITHOUT PERMISSION FROM UL d) The length of lay of the strands in both layers of a 19-wire combination round-wire unilay- stranded copper conductor shall be81 6times the outside diameter of the completed conductor. Otherwise, the length of lay of the strands in every layer of

43、 a concentric-lay-stranded conductor consisting of fewer than 37 strands shall be81 6times the outside diameter of the conductor. e) The length of lay of the strands in the outer two layers of a concentric-lay-stranded conductor consisting of 37 or more strands shall be81 6times the outside diameter

44、 of the conductor. f) The length of lay of the members or ropes in the outer layer of a rope-lay-stranded conductor shall be81 6times the outside diameter of that layer. 4.1.4 Diameter and cross-sectional area 4.1.4.1 The nominal diameters of solid and stranded conductors are shown in Tables47.Themi
