Power Resistors

OHMIC RESISTORS Resistors have been developed over a period of seventy years and are available in many different configurations of strip, plate and coil types covering a wide field of applications.
All resistor units can be supplied as open unprotected or installed in a housing for either indoor or outdoor use. Housing can be made from galvanized, powder coated steel or stainless steel materials. Whilst a range of standard units are available, designs to suit client specifications are our specialty.

Resistor Banks

Two standard bank lengths 610 and 915mm have evolved over the years, although many different sizes are provided to match application and space limitations. Material used for grid plates is a high resistivity, low temperature co-efficient, stainless steel stocked in a variety of thicknesses; plates vary in width and length providing an extensive range of rating options.

Standard plates are cut from coil and further punched to introduce a series of convolutions, which increases plate resistance. Plates are welded together to form a continuous current path with welded take off terminal points. Maximum number of plate per standard bank varies with material thickness, plates can be mixed within the banks.
