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

TRAMAG Branch Chokes – The perfect fit for Multilevel Converter Systems
Industrial drives systems require powerful converters with maximum flexibility and high availability. In addition, they must be suitable for controlling almost any type of motor and the voltage-signal must be mains-friendly as well as motor-friendly on the output side.

Sinusoidal Filters for drive systems with special requirements
TRAMAG chokes and filters are used in drives systems whose core component is a frequency converter that controls one or more motors of a machine or system. Between frequency converters and motors, caused by long cable lengths, undesirable voltage surges can occur at the motor terminals and damaging, parasitic losses can occur in the motor.
