WEIGHT AND SPACE RESTRICTIONS

Resistor elements have been designed as light as possible, however stiffened using a particular forming process. Another requirement is that the resistors must fit in available space. This often involves supplying elements which fit perfectly into even the most difficult and narrow housings. Microelettrica Scientifica manufactures compact resistors in a wide range of sizes. The maximum amount of active material can be concentrated within specified volumes while maintaining required clearances. In many cases special compact designs provide the only viable solution in traction vehicles old and new where space is limited or shapes must be irregular.
Resistors designed for traction purposes have to satisfy conflicting requirements. This is the case of braking resistors where the primary need is to employ light weight active elemnts which must have at the same time exceptional mechanical strenght.
