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.

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.

Remark: The masses given above have been obtained by calculating the values of
the calculated sectional area given in Table 3 and assuming the density to be 8,89
g/cm3 at the temperature of 20°C.
9. Length of Wire
A standard length of trolley wire and the number of jointing places corresponding
to the standard length shall be as specified in Table 5.

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.
