Si- Metal Resistors

Si- Metal Resistors

The HVR Silico resistors have high power dissipation and high energy absorption. They are manufactured mainly as rods and tubes with varying sizes. The Silico Resistors may be connected in series or parallel for various fields of application. Over 90 years of Silico developement in our company. Our Silico Rod and Tube ceramic can bear the following temperatures:
Continuous 350°C
Short time 390°C
In case of failure up to 600°C

Silicon Cabide Varistor

Silicon Cabide Varistor

The HVR SiC varistors have good voltage dependences and high energy absorption. They are manufactured mainly as discs with varying sizes, as the required electric values are most easily obtained with these geometric dimensions.One of the most advantages of a SiC Varistor is the behaviour in the case of a fault. It has a self-healing characteristic and doesn´t shorten the circuit.

Anti-Condensation Heaters

Anti-Condensation Heaters

HVR Pentagon Anti-Condensation heaters have been designed for use in switch and control gear cubicles, where a low wattage heater is required to prevent condensation. They comprise a vitreous enamelled resistor mounted in a sheet steel case and having a removable perforated sheet steel cover. There is a cable entry grommet at each end and M4 terminal screws are provided on the resistor. Dimensions and power ratings for assembled resistors are shown in the Technical Specification.

News & Innovations

HIGH PERFORMANCE PRODUCTS  The SiC Varistors manufactured by HVR in Germany are tested to extrem high temperatures. The continous operating temp. can be above 200°C (short time up to 300°C) which increase the energy capability up to 140kJ per disc.
The Si-Metal Resistor range have a cont. operating temp. of up to 350°C
For Generator de-excitation we have designed a new range named „HP-System“ to allow a better current flow performance over the stack.
