– We provide solutions e.g. for trains, hybrid vehicles, wind turbines, ships, power grids and elevators
At the Backer Group, we can offer a wide range of technologies for the production of resistors.
An advantage with resistors from Backer is that they can withstand high loads, since we use large diameter resistance wires that provide low resistance. The option of using water/liquid as cooling media enables high power resistance. We also have large element diameters, for higher voltages.
All resistors are custom made, but our standard concept speeds the development process.
The elements are fully tested for insulation and dielectric rigidity. Moreover, the elements are often built into protective cages to prevent contact with heated parts. Computerized load simulation is also performed to optimize each resistor application.
Terminal boxes with different IP classes can be used.

Numerous elements are often connected together, in series and/or parallel, to achieve the intended properties.
