GENERAL

HVR Linear Disc Resistors are manufactured from a carefully blended mixture of clays, alumina and carbon. After blending, the material is pressed to the required shape, with diameters ranging from 0.3 to 15.1cm. The resistors are then fired at high temperature in a tunnel kiln with controlled atmosphere.

This produces a Ceramic Carbon Resistor which is 100% active material and therefore of minimum size.

Aluminium is then flame-sprayed onto the flat surfaces of the resistor to provide electrical contact, and an anti-track coating is applied to the periphery to improve dielectric withstand.

With the capability of sustaining energies ranging from Joules to Mega-Joules, at frequencies up to Mega-Hz, HVR Linear Disc Resistors can be used in even the most demanding applications such as electrical transmission, traction, AC/DC drives, pulse power, dummy loads, induction heating and pulse forming networks.
