Whenever it is necessary to dissipate power peaks within an electromechanical process in a hot environment, braking resistors come into their own. In certain cases, braking resistors absorb the energy of a motor drive, thereby braking the motor. Each and every resistor designed by JOVYATLAS is suitable for use as a braking resistor.
In general, resistors from our Alpha series or our PT 1000 are used for smaller drives, while our HWS steel-grid resistors or our EN series are suitable for larger drives. JOVYATLAS has a long history of manufacturing braking resistors.

JOVYATLAS has developed in recent years into a leading manufacturer of neutral grounding resistors. As a result of continuous dialogue with our customers and a large number of completed projects we have defined complete ranges of resistors within this sector. Our grounding resistors are manufactured using state of the art production techniques. The high quality is guaranteed by our quality management department to DIN EN ISO 9001:2000. JOVYATLAS supplies grounding resistors in voltage ranges from 1 kV to 72 kV. Also available on request with the corresponding load/isolator devices

Hubbell Type SSR Power resistors from 1.3 amps through 101 amps are available, from unassembled to completely assembled in frames with covers. Standard assemblies are pre-engineered for primary or secondary resistance, and are used in typical applications such as motor starting or dynamic braking. Construction elements are stainless steel around a porcelain insulator, manufactured for endurance and reliability.
Heavy duty Types K1 and HHC resistors also utilize continuous stainless steel elements, with no weld joints where hot spots could develop. These resistors are available in ranges from 38 amps to 695 amps.
Hubbell Neutral Grounding Resistors limit the maximum fault current to a value which will not damage equipment, yet allow sufficient fault current for protective relays to clear the fault, conforming to IEEE Standard 32-1972

JOVYATLAS resistors for railway application are developed for the high load sector and designed to suit the individual requirements of the stretch of line concerned. All resistors for railway application are assembled using selected stainless steels and ceramic spacers. For stability, resistor bands are spot welded with aerodynamics in mind in a meander form and physically positioned in sequence so that they maintain their shape. A special design ensures that the bands are held securely and able to be grouped together in modules.

The heating element is printed on a thin and flexible support and can therefore be placed in very narrow spaces, also adapting to curved surfaces.
Very easy fitting.
Numerous shapes are possible, including holes and slots for applications where required.
The desired temperature is reached quickly and with low energy consumption.
Differentiated heat generation can be obtained.
The back of the resistor may be adhesive.
Various types of electrical insulation are possible according to the place where the resistor has to operate.
They can be produced at any voltage, including low.
