Dimensions and Permissible Variations7.1 The size shall be expressed as the nominal area of crosssection in circular mils.7.2 The standard sizes of figure

18、all not vary more than 65%from that specified in Fig. 1 and Fig. 2, respectively.7.5 Conformance of the trolley wire to the specified dimen-sions shall be determined by taking the measurements shown inFig. 1 and Fig. 2 under heading, “Dimensions for Inspection,in.” The shape of the groove for figure
19、-9 trolley wire shall bechecked with the“ go” and“ no-go” slip gages described in Fig.3. The gages shall be applied to the ends of the samples takenfrom each reel. Samples shall be clean and ends free fromburrs. The groove shall be considered as conforming to thisspecification if the “go” gage can b
20、e pushed on the straightenedwire by hand and the “no-go” gage cannot be pushed on thewire.8. Resistivity8.1 Electrical resistivity shall be determined on representa-tive samples by resistance measurements (Explanatory Note 2).At a temperature of 20C the resistivity shall not exceed900.77 lb/mile.28.
21、2 The electrical resistivity of the material shall be deter-mined in accordance with Test Method B193.9. Density9.1 For the purpose of calculating weights, cross sections,etc., the density of the copper shall be taken as 8.89 g/cm3(0.32117 lb/in.3) at 20C (Explanatory Note 3).10. Joints10.1 No joint
22、s shall be made in the completed wire. Joints inthe wire and rods made prior to final drawings shall be inaccordance with the best commercial practice, and shall becapable of meeting the tensile strength requirements in 5.3.11. Workmanship, Finish, and Appearance11.1 The wire shall be of uniform siz
23、e, shape, and qualitythroughout, and shall be free from all scale, flaws, splits, andscratches not consistent with the best commercial practice.12. Inspection12.1 All tests governing the acceptance or rejection of thewire, unless otherwise specified, shall be made at the place ofmanufacture with app
24、aratus furnished by the manufacturer andin the presence of the purchaser or his representative, who shallbe furnished a copy of the tests. The manufacturer shall affordthe inspector representing the purchaser all reasonablefacilities, without charge, to satisfy him as to the reliability ofthe result
25、s before the wire is delivered. If the purchaser waivesinspection, and if he so elects at that time, he shall be furnishedwith a certified copy of tests made by the manufacturer.13. Rejection13.1 Any reel of wire that fails to conform to the require-ments prescribed in this specification may be reje
26、cted. Failureof 30 % of the number of reels ready for inspection at one timeshall be deemed sufficient cause for rejection of the whole lot.14. Packaging and Package Marking14.1 All wire shall be shipped on substantial reels, suitablefor the weight of the wire handled, and shall be well protectedfro
27、m injury. The diameter of the reel drums shall be sufficientlylarge, not less than 30 in. (762 mm), to eliminate difficulty withwaves or kinks when the wire is strung. If reels are to belagged, it shall be so specified by the purchaser. The wire shallbe reeled with turns tightly together, in uniform
28、 layers, freefrom kinks and crosses. The relation between the vertical axisof grooved wire as finally strung and the axis of the reel shallbe as specified by the purchaser and shall be approximatelyconstant.14.2 The ends of the wire shall be securely fastened to thesides of the reel with no less tha
29、n six staples. The staples shallbe at least 2 in. (50 mm) in length and made from wire not lessthan 0.145 in. (3.7 mm) in diameter. Care shall be exercised instapling so that there is no damage to the surface of the exposedlayer of wire. All reels shall have the arbor holes reinforcedwith steel plat
30、e at least12 in. (12 mm) in thickness. Unlessotherwise specified, round arbor holes shall be for a 212-in.(63.5-mm) shaft.14.3 The length or the weight of wire to be wound uponeach reel shall be agreed upon between the manufacturer andthe purchaser in placing individual orders.14.4 Reels shall be ma
31、rked legibly and indelibly with theserial number, size, kind, length, and weight of wire, and suchother information as is specified by the purchaser.TABLE 1 Tensile Requirements for Figure-8 WireNominal Area,cmilsTensileStrength,min, psiElongationin 10 in.,min, %350 000 42 800 4.50211 600 46 600 3.7

33、slow-speedindustrial haulage applications, usually in connection with groovedcollectors or trolley wheels. The figure-9 deep-section grooved trolleywire supplements the figure-8 design in the largest sizes and is designedfor use with trolley wheels or grooved collectors. The “American StandardGroove
34、d Trolley Wire Sections” (the Standard Design of the AmericanTransit Engineering Association) are prescribed in Specifications B9 andB47. These sections are designed for sliding and roller type collectors aswell as for grooved and wheel type collectors, the section being wider inproportion to the de
35、pth.NOTE 2It is known that the rapidity with which load is applied to asample during tension testing affects the performance of the sample to agreater or lesser extent, depending upon many factors. In general, testedvalues of tensile strength are increased and elongation values are reducedwith incre
36、ase in speed of the moving head of the testing machine.However, there are speeds below which no practical change is observable.It is suggested that tests be made at speeds of moving head that, underno-load conditions, are not greater than 3 in. min, but in no case at a speedgreater than that at whic
37、h correct readings can be made. No minimumrestriction on speed of testing seems necessary.NOTE 3“Resistivity” is used in place of “percentage conductivity.”The value of 0.15328 g/m2at 20C is the international standard for theresistivity of annealed copper equal to 100 % conductivity. This termmeans
38、that a wire1minlength and weighing 1 g would have a resistanceof 0.15328. This is equivalent to a resistivity value of 875.20lb/mile2which signifies the resistance of a wire 1 mile in length weighing 1 lb. Itis also equivalent, for example, to 1.7241 /cm of length of a bar 1 cm2in cross section. A c
