Protect the environment by increasing energy efficiency
Backer supplies a wide range of resistors used in many diffrent applications, helping to protect the environment by increasing energy efficiency. Wind turbines, industrial drive systems, public transport systems, marine propulsion, and nuclear research institutes – all need resistors to increase the efficiency of their systems. We use thermal simulation software to optimize and customize our solutions to perfectly align customer requirements with customers and specific applications.
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 External link. with different IP classes can be used. Numerous elements are often connected together, in series and/or parallel, to achieve the intended properties.
- Brake resistors
- Power resistors
- Load resistors
- Shunt resistors
- Water-/liquid cooled resistors
NOVI SAJT BACKER:
Backer offers a very wide range of both air- and liquid-cooled resistors, adapted for applications such as braking resistors, charging resistors, discharge resistors and energy dumping resistors.
We provide various technologies for the manufacture of resistors. Our resistors can handle high loads and high power effect when they are manufactured with a resistance wire with a large diameter and with the possibility of cooling down with water / liquid. We also manufacture resistors with large pipe diameters, which withstand high voltage. The elements of our resistors are tested to check their insulation and dielectric strength.
To prevent contact with heated parts, we often build the elements into protective housing. In addition, computerized simulation of pulse load is performed to optimize all resistor applications.
