Connection technology made by TRAMAG
– What you can rely on
Insights into the transformer and choke production of a leading specialist
The quality of transformers, chokes and filters depends to a large extent both on their materials and on how these materials are combined and connected. TRAMAG has been an expert in the production of inductors for many years and has enormous expertise, especially in the electro-technical safety-relevant, low-impedance connection technology.

Cu/Cu connections
In this method of connection technology, the copper material of both connecting parts is joined together by brazing, i.e. by heat. The result is a highly stable, electrically and thermally robust connection, the conductivity remains fully intact.
Al/Cu connections
Another method of joining connecting parts is the cold pressure welding process. In this process, the material consisting of the different non-ferrous metals, aluminium and copper, is joined together not by heat but by friction and pressure. This process also ensures the required connection cross-section.

We are champions in joining connections with metals

High flexibility in the implementation of advanced connection technology
- Different types (lug, clamp, stranded wire, bolt) and positions (front, rear, top, bottom) of connections possible
- Several material variants possible
- Tape for high currents
- Round wire (also very thin wires for higher voltage)
- Flat wire for higher currents and better utilisation of winding space
- HF stranded wire for higher frequencies
- Different combinations (e.g. aluminium tape/copper lug) possible
Optimized for every customer application
TRAMAG offers the best quality for safe operation and the most efficient economy in the installation of connections.
Our products are perfectly matched to your systems and thus create maximum system availability and function of the drive or machine.
