The main objective of this high-tech product range, based on extremely thin insulating material and on a specific bonding process, is to optimize the electrical parameters and constraints (inductance, skin effect, creepage distances, etc.).

Amphenol AUXEL has the expertise to guarantee this optimization over a wide range of the functional parameters (current, voltage, frequency, etc.) and the applicable constraints (reliability/partial discharge, thermal and space issues, etc.). Moreover, we will work with you to optimize materials and processes in order to lower the unit price.

OLST technology (Optimized Local Surface Treatment) is a plating of copper on aluminium. The two metals are inseparably welded together in a special process based on dynamic gaz cold spray associated to a fast moving robot.

This process combines the advantages of light metals (low weight, easy workability, etc.) with the advantages of copper, such as corrosion resistance, the property of being soldered, special features for electrical purposes.

We design and propose complete solutions in order to limit the cost of a function and time for assembly.

We provide our expertise and help you to improve your system performances, extend its lifetime, limit its weight, and reduce service and peripheral costs.

AMPHENOL AUXEL offers an optimized approach for high voltage low inductive interconnections: use of specific material, low inductive design with respect of creepage distances and efficient control of partial discharge…

Typical applications: traction converters, wind energy converters, MV power conversion systems, SiC (Silicon Carbide power switching components).

Energy management is at the heart of the concerns of many industries. Development engineers always look for solutions to improve the technical characteristics of their systems: higher nominal voltage and current, higher power density level, efficiency close to 100%…

All these developments invariably lead to system operating temperature strong increases.

Datacom equipment often requires compact and reliable solutions for power distribution. AMPHENOL AUXEL designs and produces specific distribution busbars for this application.

What is OLST?

Replace copper electric conductors by aluminium with copper on the contact surfaces. OLST is a coating operation based on the high-speed projection of micro-particles on a surface.

The two metals are inseparably linked together in a special process based on dynamic gas cold spray associated to a fast moving robot.

Varnished  Insulated (Laminated) Busbar

It is a matter of replacing the insulation film or powder coating  with insulation used in motor industry, particular enamelled wire.

VILB Project is a technological transfer between the electric motor industry (enamelled wire) and static power inverters.

Innovative characteristics developed for the project :

  1. Based on varnish solvent free
  2. Possible assembly with UV thermo-adherent glue
  3. Micro-spraying technology  (thin multi-layers)
  4. UV LED curring
  5. Filler (micro& nanopowder) to increase performance
