Custom electrical solutions for every project
At Casa Masfarné, we design and manufacture custom electrical connections, specifically developed to adapt to the technical requirements of each installation, equipment, or machinery. Thanks to our extensive experience in the sector and our production capacity, we are able to offer completely tailored solutions for industrial, energy, railway, automotive, and other applications.
At Casa Masfarné, we manufacture flat connections from our own high-conductivity copper braids, assembled with electrolytic copper tube terminals, cut and pressed to measure with precision and high pressure. These connections are designed to offer excellent conductivity, mechanical flexibility, and vibration resistance.
Mass connections are made of a laminated flat braid, with tinned and crimped ends to facilitate installation. Available in various sections, these connections adapt to the specific needs of each project, ensuring mechanical resistance and excellent conductivity.
Copper foil connections are composed of thin sheets of polished copper with thicknesses of 0.10 mm or 0.30 mm. At the ends, two copper plates are placed to make the connection holes or are press-welded together for greater robustness. We can manufacture connections of up to 5,000 mm², adapting to the specific needs of each […]
At Casa Masfarné, we can manufacture any type of electrical connection adapted to the specific specifications of each client. This includes connections formed by multiple braids or round cables, water-cooled connections, connections with different types or numbers of terminals at each end, among other special solutions. Do not hesitate to contact us to develop any […]
Our Litz wire connections are designed and manufactured for high-frequency environments, with adequate insulation according to the specific use.
The round connections are made with our own round cables. For this type of connection, commercial crimped terminals are normally used, guaranteeing a safe and efficient connection.
At Casa Masfarné, we offer customized insulation solutions for all our electrical connections, adapting to the specific needs of each project.
We manufacture connections using flat, round, or foil conductors to ensure optimal adaptation to each type of installation or available physical space.
We offer multiple options, from standard terminals and tube terminals to press-welded terminals, selecting the best solution based on the application and required connection capacity.
We can adapt the number, diameter, and arrangement of the holes in the terminals to ensure precise integration with the client’s components.
The electrolytic copper we use in our products is of high purity (99.9%), obtained through electrolysis (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:

| Grade | Min. Coating Thickness (µm) | Max. Coating Continuity (g/m²) | Coating Adhesion |
| A | 0,30 | 1,0 | No black cracks |
| B | 0,60 | ||
| C | Not Specified* | ||
| (*) The coating thickness when not specified is subject to agreement between the customer and the supplier. | |||
We offer a range of diameters from 0.05 mm to 1 mm, allowing for different degrees of flexibility, mechanical resistance, and current capacity.
Our connections range from 0.75 mm² to 3,000 mm², making them suitable for both low-power applications and high electrical demand installations.
To ensure electrical safety and environmental resistance, we offer different insulation systems:
At Casa Masfarné, we combine more than 130 years of experience with cutting-edge technology to offer completely tailored Litz wire solutions, meeting the most demanding electrical, thermal and mechanical requirements of the current market.
