The series of resistors is installed by ZB1 constantan coiled elements or ZB2 constantan coiled elements and Fe-Cr-Al elements.resistors are put together by mica insulating pipe's two whoris,fixed on the right and left walls made of thin iron plate;its outlet leads to wiring board made of insulating plate for users to wiring.(structure and principe of Fe-Cr-Al elements are same as that of ZX15 resistors).except for using in total piece,resistor resistance value can also be adjusted by taping in the center.
Specifications
RT series resistors are mainly used for cranes with JZR2 series motors for starting adjustment resistors. RT series series resistors are used with cam control KT12 series, KT10 series, KT14 series, KT16 series and KTJ15 series.
