Cressall Resistors

Cressall Resistors offers a wider range of technologies than any other power resistor manufacturer in the world and over 100 years’ experience in the design and manufacture of electrical resistors for use in power generation, high voltage and medium voltage power distribution, marine and offshore electrical systems, drives and controls for cranes, hoists and industrial machinery, rail traction and standby power systems. We make neutral earthing and neutral grounding resistors for medium voltage electrical distribution networks; dynamic braking resistors for inverter drives; portable load banks for testing diesel generators, uninterruptible power supplies and batteries; dummy loads for the routine testing and operation of diesel power plant and high voltage filter resistors which form part of HVDC converter stations and Capacitor Damping Networks. Cressall has developed a new lightweight and very compact liquid cooled resistors for the braking systems of hybrid and all-electric vehicles. Our range of edge-wound, grid, wire-wound, strip, expanded mesh and sheathed element resistor technologies enables us to offer appropriate and cost-effect designs for all these applications, using natural convection, fan cooling or water cooling either directly or indirectly by heat-exchanger.
