34、f Specification B230/B230M.4.2 Before stranding, the 6201-T81 wire used shall meet therequirements of Specification B398/B398M.5. Joints5.1 In conductors composed of seven wires, only cold-pressure welds and electric butt, cold-upset welds may be madein the six outer finished wires. No welds are per

35、mitted in thecenter core wire. In other conductors, cold-pressure welds,electric-butt, cold-upset welds, or electric-butt welds may bemade in the finished wires. Such joints in the same wire or anyother wire in the conductor shall be not closer than prescribedin Table 3. Following welding, electric-

36、butt welds in 6201wires shall be annealed for a distance of at least 6 in. (150 mm)on each side of the weld (Explanatory Note 2).6. Lay6.1 The preferred lay of a layer of wires is 13.5 times theoutside diameter of that layer, but the lay shall be not less than10 nor more than 16 times this diameter.

37、6.2 The direction of lay of the outer layer shall be right-handunless specified otherwise by the purchaser. The direction oflay shall be reversed in successive layers.6.3 In a conductor having multiple layers of aluminumwires, the lay ratio of any aluminum layer shall not be greaterthan the lay rati

38、o of the aluminum layer immediately beneathit.7. Construction7.1 The number and diameter of wires and the areas of crosssection of conductors shall conform to the requirementsprescribed in Table 1 or Table 2.7.2 Recommended standard strandings are as shown inTable 4.8. Strength of Conductor8.1 The r

39、ated strength of completed conductors shall betaken as the aggregate strength of the aluminum 1350 and thealuminum-alloy 6201 components, calculated as follows. Thestrength contribution of the aluminum 1350 wires shall betaken as the percentage indicated in Table 6, of the sum of thestrengths of the

40、 aluminum 1350 wires, calculated from theirspecified nominal wire diameter and the appropriate specifiedminimum average tensile strength given in Specification B230/B230M. The strength contribution of the aluminum-alloy 6201wires shall be taken as that percentage, according to thenumber of layers of

41、 aluminum-alloy 6201 wires, indicated inTable 6, of the sum of the strengths of the aluminum-alloy6201 wires, calculated from their specified nominal wirediameter and the minimum stress at 1 % extension. This shallbe considered to be 95 % of the minimum average tensilestrength specified for the wire

42、 diameter in Specification B398/B398M.8.2 Tests for determining the rated strength of the completedconductor are not required by this specification but may bemade if agreed upon by the manufacturer and the purchaser atthe time of placing an order. If tested, the breaking strength ofthe completed con

43、ductor shall be not less than the ratedstrength if failure occurs in the free length at least 1 in. (25mm) beyond the end of either gripping device, or shall be notless than 95 % of the rated strength if failure occurs inside, orwithin 1 in. (25 mm) of the end of, either gripping device(Explanatory
