Shielding braids consist of bobbin wires, located parallel, which have been braided into a tube. Manufactured from Cu-ETP1, Cu-OF1, LEONI-Histral®-alloys (upon request), aluminium and stainless steel, with coating in bare, tin-plated, nickel-plated or silver-plated, hard or soft annealed. Sinlge-wire diameter ranging from Ø 0.10 mm to Ø 0.40 mm. Cross-section ranging from 0.25 mm² bis 400 mm². Tubular shielding braid is smoothly expandable and has a very good shielding effect. The couverage can be determined precisely by changing the braiding angle. Suitable for electrical and mechanical shielding of wires, cables, cable bundles and cable harnesses.

Round copper wires made from Cu-ETP1 and Cu-OF1 in bare, tin-plated, nickel-plated, silver-plated or gold-plated, soft annealed. Single-wire diameter ranging from Ø 0.05 mm to Ø 0.51 mm. Number of wires used for strands: between 3 and 24 wires (subject to single-wire diameter).

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.

High-flexible round strands and ropes made from Cu-ETP1, Cu-OF1, aluminium and LEONI Histral® alloys (upon request) in bare, tin-plated, nickel-plated and silver-plated, hard or 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 630 mm² (bigger cross-sections upon request). High-flexible round strands and ropes are mainly suitable for earthing straps, connectors, conductors for low-voltage lighting and for welding technology.

Round copper wire made from Cu-ETP1 and Cu-OF1 in bare, tin-plated, nickel-plated, silver-plated or gold-plated, hard or soft annealed. Single wire diameter ranging from Ø 0.04 mm to Ø 1.8 mm. Single wire for high-frequency (HF) technology: High-precision silver-plated single wire used as core for coaxial cables, size range from 0.10 mm to 1.8 mm. This single wire is manufactured on a specially designed machine and is characterised by a highly constant diameter, outstanding centricity and an extremely pure surface.

Contured fabric tapes, braided into a tube and then flat-rolled. Made from Cu-ETP1 and Cu-OF1, LEONI Histral® alloys upon request, in bare, tin-plated, nickel-plated or silver-plated, hard or soft annealed. Single-wire diameter ranging from Ø 0.05 mm to Ø 0.40 mm. Cross-section ranging from 25 mm² to 120 mm². Our flat-rolled fabric tapes are characterised by straight rectangular edges with a very high degree of dimensional accuracy and very close tolerances. There is an adjustable degree of compaction, with cross-section remaining unchanged, as well as an easy combination of different cross-sections laid on top of each other (modular system). Contured, braided copper tapes have an improved weldability in automated production processes for manufacturing of earthing straps, connectors or electrotechnical components.

Compact braided round copper flexibles made from Cu-ETP1 and Cu-OF1, LEONI Histral® alloys upon request, in bare, tin-plated, nickel-plated or silver-plated, in hard or soft annealed. Single-wire diameter ranging from Ø 0.05 mm to Ø 0.10 mm. Cross-section ranging from 0.047 mm² to 25 mm² (bigger cross-sections upon request). Round copper braids are characterised by a very high degree of dimensional accuracy and a very high Flex life. They are absolute free from twist and support an automatic further processing. Compact braided round copper flexibles are particularly suitable for carbon brushes industry, connection technology, switches or aviation industry.

High-flexible copper-based ropes, enclosed by an additional braid, made from Cu-ETP1, Cu-OF1 and LEONI Histral® alloys (upon request) in bare, tin-plated, nickel-plated and silver-plated, hard or soft annealed. Single-wire diameter ranging from Ø 0.05 mm to Ø 0.10 mm. Cross-section ranging from 0.35 mm² to 120 mm² (bigger cross-sections upon request). Our ropes with overall braids are characterised by their good flexibility and their excellent mechanical strength. The overall braid has a vibration-reducing function and prevents unrevelling of the rope. Ropes with overall braids are mainly suitable for automotive, industrial applications and for connectors.

Strands with a concentric structure made from Cu-ETP1, Cu-OF1 and LEONI Histral® alloys 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 630 mm². The individual wires are subject to an exact positioning around a core wire, which ensures an all-out uniform structure. Concentric strands are particularly appropriate for thin-gauge coating with high-grade isolation materials (extrusions). 7-end strands are especially suited for data cables with high frequencies of transmission. The technical qualities of a concentric strand can be extremely well and accurately customized by combining several different alloy wires.

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.

Strands with a semi-concentric structure made from Cu-ETP1, Cu-OF1 and LEONI Histral® alloys 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 0.03 mm² to 16 mm². The individual wires are subject to an exact positioning, yet without an additional core wire, which ensures an all-out uniform structure. Concentric strands are particularly appropriate for thin-gauge coating with high-grade isolation materials (extrusions). The technical qualities of a semi-concentric strand can be extremely well and accurately customized by combining several different alloy wires.
