1 Scope
This standard specifies the characteristics of copper and copper alloy wires of cross
sections of 80, 100, 107, 120 and 150 mm² for use on overhead contact lines.
It establishes the product characteristics, the test methods, checking procedures to be
used with the wires, together with the ordering and delivery condition.

3 Definitions
3.1
drawing stock or intermediate rod stock
wire generally of circular shape, whose cross section is larger than the wire cross
section, from which the contact wire is then drawn
3.2
wire
electric conductor of an overhead contact line with which the current collector makes
contact and is characterised by two clamping grooves. The wire herein after will be
referred to as wire or wires
4 Characteristics of wires
4.1 Material designation
The drawing stock or intermediate rod stock shall be a copper or copper silver as
defined in standard EN 1977 or a copper cadmium, copper magnesium or copper tin
alloy. Table 1 gives the designations of the drawing stocks or intermediate rod stocks
for the possible composition of the grooved contact wire. At the time of tender the user
shall specify explicitly the material(s) he wants or he is allowed to apply.

4.2 Appearance and condition
The wires shall not present any imperfections (roughness, sliver, seam, inclusion)
liable to affect the mechanical and/or electrical properties specified in this standard or
to cause difficulties during installation/operation.
The surface shall be clean and free of oxide inclusions or sulphide generated during
the manufacturing process or foreign substances such as pickling residue.
The colour of the metallic bright surface immediately after manufacturing may change
due to atmospheric influence and is acceptable.
4.3 Identification grooves
To identify the different copper (alloys) used as contact wire, identification grooves are
used;
4.3.1 Normal and high strength copper (CuETP, CuFRHC, CuHCP, CuOF)
1)
Wires of copper have no identification grooves .
4.3.2 Copper-silver alloy (CuAg 0,1)
Wires of copper alloy with silver shall incorporate two identification grooves on the
upper lobe of the wire in accordance with Figure 1.
4.3.3 Copper-cadmium alloy (CuCd 0,7, CuCd 1,0)
Wires of copper alloy with cadmium shall incorporate one identification groove on the
1)
upper lobe of the wire in accordance with Figure 2 .
4.3.4 Copper-magnesium alloy (CuMg 0,2, CuMg 0,5)
Wires of copper alloy with magnesium shall incorporate three identification grooves on
the upper lobe of the wire in accordance with Figure 3.
4.3.5 Copper-tin alloy (CuSn 0,2)
Wires of copper alloy with tin shall incorporate one identification groove set at an angle
of 24° on the upper lobe of the wire in accordance with Figure 4.
1) See annex D, special national condition for United Kingdom.
IDENTIFICATION GROOVES
4.4 Configuration and cross sections
4.4.1 Clamping grooves
Whatever cross section of the wire is used, the dimensions of the clamping grooves
shall be in accordance with either type A or type B as given in Figure 5.
Type A clamping groove Type B clamping groove

4.4.2 Cross-section areas
This standard details the following nominal cross sections: 80, 100, 107, 120 and
150 mm².
4.4.3 Profiles
Profiles are of two main types, the circular profile and the flattened profile.
