32、 3 Terms and definitions For the purposes of this document, the following terms and definitions apply. 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

33、conductor of an overhead contact line with which the current collector makes contact and is characterised by two clamping grooves Note 1 to entry The wire herein after will be referred to as wire or wires. 4 Characteristics of wires 4.1 Wire designation system The wire designation shall consist of -

34、 denomination (Wire); - number of this European Standard (EN 50149); BS EN 50149:2012EN 50149:2012 (E) 7 - configuration designation (see 4.5.4); - material designation, either symbol or number (see Table B.1, or material as agreed between purchaser and manufacturer). EXAMPLE: Wire EN 50149 AC-120 C

35、uMg0,5 or Wire EN 50149 AC-120 CW128C or Wire EN 50149 AC-120 CuMg0,5 (high conductivity) 4.2 Material designation The drawing stock or intermediate rod stock shall be a copper or copper silver alloy as defined in EN 1977:1998 or another copper alloy. Annex B gives the designations of the drawing st

36、ocks or intermediate rod stocks for some possible composition of the wire. At the time of tender the user shall specify explicitly the material(s) he wants or he is allowed to apply. NOTE Copper cadmium alloys are not recommended for use for environmental reasons. 4.3 Appearance and condition The wi

37、res shall not present any imperfections (roughness, sliver, seam, inclusion or cracks) liable to affect the mechanical and/or electrical properties specified in this European Standard or to cause difficulties during installation/operation. The surface shall be clean and free of oxide inclusions or s

38、ulphide 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. This is acceptable. 4.4 Identification 4.4.1 General requirements All wires manufactur

39、ed from alloys shall be clearly identified. For normal and high strength copper and copper-silver, copper-cadmium, copper-magnesium and copper-tin alloys the method of identification shall be by identification grooves as shown below. For other alloys the identification method (whether grooves or oth

40、er method) shall be agreed between purchaser and manufacturer. Identification grooves shall be set out as shown in Figure 1. The centre of the middle circle shall be on the projected circle of the contact wire. The connection between two successive arcs shall be without a straight line. BS EN 50149:
