Copper strands - Import export

Several bunched single wires or bundles made from Cu-ETP1 and Cu-OF1 in bare, tin-plated, nickel-plated or silver-plated, soft annealed. Single-wire diameter ranging from Ø 0.05 mm to Ø 0.51 mm, left-hand lay or right-hand lay. Cross-section ranging from 0.005 mm² to 630 mm². 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. 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. Owing to their good efficiency our bunched single wires are versatile in a multitude of applications in cables and conductors.

Semi-concentric or concentric strands with very short lay lengths and an extraordinarily smooth surface made from Cu-ETP1 and Cu-OF1 in bare, tin-plated, nickel-plated or silver-plated, soft annealed. Single-wire diameter ranging from Ø 0.05 mm to Ø 0.51 mm, left-hand lay or right-hand lay. Cross-section ranging from 0.02 mm² to 16 mm². LEONI has had its manufacturing process specifically dedicated to this type of product patented. LEONI smooth bunches boast an exceptionally compact and precise round structure and have a very good Flex life. They are particularly suitable for moving applications and for thin-gauge coating with high-grade isolation materials benefitting from a long flex life as well as weight and space efficiency.

Compacted material terminals made from Cu-ETP1 and Cu-OF1, in bare and tin-plated, nickel-plated and silver-plated upon request, in hard or soft annealed. Cross-section ranging from 1 mm² to 95 mm² depending on welding area. Compact welded terminals of different copper strands can be automated processed. A production of individual parts is possible as well as large-scale production. Resistance welded strands by LEONI are particularly suitable for high-voltage battery connectors, for high power connectors, for switch contacts and for special applications.

These cables are made of multi-stranded copper wire conductors which makes them very flexible. Galvanised steel wire provides protection against corrosion and oxidation and ensures additional mechanical protection. They are commonly used in industrial machines, heating and air conditioning systems, fuel pumps. They can be used in dry or moist places with medium mechanical stress and where flexible application is required.
