Spiroid Braids
High-quality spiral braids
The braids are made of fine strands of annealed electrolytic copper, which offer great flexibility and a small bending radius. They are manufactured with unit wires of 0.10 mm and 0.25 mm in diameter. The spiroid structure provides greater firmness to the final cable and improves its geometry.

Specifications
The electrolytic copper we use in our products is purity 99.9%, (Cu-ETP according to EN 13602 standard).
The annealing process subjects the material to heat treatment, making it more malleable and flexible, improving its mechanical properties without altering its electrical ones.
| Copper Composition (Cu-ETP) | |
| CU-ETP: 99,9 % min. | |
| Se-Te-Bi: 3 ppm (Max) | Cr-Mn-Sb-Cd-As-P-S: 15 ppm (Max) |
| Sn-Ni-Fe-Si-Zn-Co: 20 ppm (Max) | Ag: 25 ppm (Max) |
We use two types of copper:
- Polished Copper (Cu)
It has a smooth and shiny surface. It is mainly used in the manufacture of electrical equipment, indoor installations, and other applications where excellent conductivity and surface finish are required. - Tinned Copper (CuSn)
It has a tin coating that protects the copper from corrosion and oxidation. The coating thickness complies with EN 13602 (Classes A, B, or C). It is commonly used in marine wiring, outdoor installations, and industrial applications where corrosion resistance is essential.
