JAPANESE INDUSTRIAL STANDARD Hard-Drawn Grooved Trolley Wires



JIS E 2101-1990



1. Scope This Japanese Industrial Standard specifies the hard-drawn copper grooved trolley wires (hereafter referred to as trolley wires). Remark:



The units and numerical values given in { } in this Standard are based on the International System of Units (SI) and are appended for informative reference. Further, the traditional units and numerical values shall be replaced by the accompanying SI units and the relevant converted values given in { } on January 1, 1991.



2. Classification The trolley wires shall be classified into five classes listed below according to nominal sectional area. 70 mm2, 85 mm2, 110 mm2, 150 mm2, and 170 mm2 3. Quality The trolley wires shall be homogeneous in quality, smooth in surface and free from defects such as flaws, rust, cracks, twist and others. 4. Electric Conductivity The trolley wires shall show an electric conductivity of 97,5% or over when subjected to the test specified in JIS C 3001. 5. Tensile Properties The trolley wires shall be subjected to the tests prescribed below and the determined tensile load and elongation shall satisfy the requirements specified in Table 1. (1)



The gauge length of the test piece shall be 250 mm.



(2)



When the test piece breaks down either within 25 mm from a bench mark inside the gauge length or outside the gauge length and at the same time the test result fails to meet the requirements specified in Table 1, the test shall be invalidated.



(3)



When a test result fails to meet the requirements specified in Table 1, two additional test pieces shall be taken from the same test specimen for each test piece and the average of the results obtained from the three test pieces shall be adopted as the test result.

6. Bending Bend a trolley wire approximately 90° in a plane including the center line of its arc face, along an arc having the radius given in Table 2 according to its radius, with its small arc face facing inward (call this action the first bending), next return its original form (call this the second bending), further bend it approximately 90° in the opposite direction (call this the third bending) , and then return to its original form, thus making up one cycle of bending. Even after 8 cycles, the trolley wire shall not be broken and severed. This bending operation shall be performed gently. Class (nominal sectional area) mm2

7. Shapes and Dimensions The shape and dimensions of the trolley wires shall be as specified in Table 3 and Figure. The diameter A (noted in Table 3 and Figure, and so forth) and the dimensions B, D and E shall be measured at three or more points including both ends and middle points for each length. The tolerances on diameter A and on dimensions B, D and E shall be ±1% and ±2% respectively.

Unless otherwise specified by the purchaser, within 5% of addition or reduction is permitted to the standard length specified above. 10. Jointing Jointing shall be conducted prior to wire drawing either by silver soldering or by a method not inferior to it. The finished length measured along the wire axis shall be at least six times the diameter for silver soldered wires. The tensile load for the jointed portion shall be at least 95% of the value given in Table 1 of Clause 5. The jointing place shall be exempted from the application of the rule governing the elongation stipulated in 5 and the rule governing the bending stipulated in 6. 11. Packaging Each length of the trolley wires shall be wound around a robust drum with its small arc face outside so as not to twist, and then enclosed with tough sidepieces. The above-mentioned drum shall have the barrel diameter of at least 45 times the diameter of the trolley wire, the outside width of 75 cm or under, and the flange diameter of 120 cm or under. The drum shall have a strong axis bore 6,5 cm or over in diameter. The drum shall bear a clear statement of the following details on the outside. Class, Length, Masses (both gross and net), Turning direction during transportation of drum,

6 E 2101-1990 Annex The values of tensile strength based on the traditional units given in 5. (3) of the main text of this Standard shall be converted, on January 1, 1991, to the numerical values in the SI units listed below. Tensile Properties (3)



When a test result fails to meet the requirements specified in Annex Table 1, two additional test pieces shall be taken from the same test specimen for each test piece and the average of the results obtained from the three test pieces shall be adopted as the test result.
