Resistors

Speedage Engineers offers Resistors. These are stainless steel wire grid type resistors. These consist of corrosion resistant stainless steel wire or strips in the form of grids. The current rating generally ranges from 7 A to 80 A continuous. Higher ratings are possible by using multiple parallel paths. The main advantages are reliability, compactness, light weight and relatively low cost. The grid materials are generally of high resistance strip or wire. The drawn resistor materials are uniform in section and free from any flaw or unevenness likely to cause local heating. Suitable sizes of strip are employed to give a wide range of current ratings. They are particularly efficient on continuous duty. The resistors element consists of a continuous length of resistance strip or wire of uniform section formed into the required number of loops and bents so as to for a typical grid or element. These are then mounted on mica insulated steel rods, with mica washers between steel spacers acting as grid separators. The whole assembly thus forms a grid and open tier or stack. Each tier is mounted between two-pressed steel and frames with flanged for bolting to other boxes. Up to six standard boxes can be assembled in this way end the complete resistor enclosed by louvered covered and drip proof top cover. The terminals are easily accessible and are made of heavily plated metal, and each one is securely clamped between the grids.
