Resistors
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.

Product examples
Product examples:
- Brake resistors
- Power resistors
- Load resistors
- Shunt resistors
- Water- / liquid cooled resistors
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.
