– We supply solutions e.g. for trains, hybrid vehicles, wind turbines, ships, power grids and elevators
Within the Backer Group we can offer a wide range of technologies for production of resistors.
An advantage with resistors from Backer is that they can withstand high loads, since we use large diameter resistance wires which gives low resistance. The posibility to use water/liquid as cooling media enables high power resistance and we also offer large element diameters, which withstands high voltage.
All resistors are custom made, but our standard concept speeds up the development process.

Examples of applications:
The elements are 100% tested for insulation and dielectric rigidity. Also, the elements are often built into protection cages to prevent contact with heated parts. Also, computerized load simulation is done to optimize each resistor application.
Terminal boxes with different IP class can be used.

Numerous elements are often connected together, series and/or parallel, to achieve intended properties.
The Backer Group, is an expert on electric resistors and brake resistors. They are known world-wide for the qualified design and hi-quality production of resistors for e.g. electro mechanic-, wind power mill- and the tele-com industry.
