ABSTRACT:
A rigid frame supported resistor for dynamic braking of electric and diesel-electric locomotives has certain of the frame elements cushioned or insulated from each other and the resistance ribbon insulated and cushioned from the frame. Organic insulating material in molded or sheet form, preferably a copolymer, such as a polyester resin, protected by a metal heat shield, may be used for structural frame members, or for cushioning and insulating metal structural frame members. The organic insulating resistant is supplemented by ceramic insulating material in locations subject to high heat.
