Copper electrical wire

flexiblemulti-strandfor railway applications

Several single wires or bundles are bunched together. Those single wires do not hold a fixed position inside the strand. Their position relative to one another undergoes a permanent change along the entire length of the bunch. Applications • A multitude of applications in cables and conductors • Crucial advantage: good efficiency Particular benefits for our customers • Uniform elongation of single wires • Low tolerances, even in single wires (even outperforming ASTM) Manufacturing range • Materials: Cu-ETP1 and Cu-OF1 • Bare, tin-plated, nickel-plated or silver-plated • Left-hand lay or right-hand lay • Variation: soft annealed • Single-wire diameter: ranging from Ø 0.05 mm to Ø 0.51 mm • Cross-section: ranging from 0.005 mm2 to 630 mm2 Construction The construction of a bunch is derived from the cross-section required, which leads to the electrical conductor featuring a certain resistance level. Different cross-sections with the same resistance value can be generated by applying single wires of varying sizes.
