Kev xaiv ntawm nro clamps feem ntau yog txiav txim siab raws li qhov sib txawv ntawm cov khoom siv hluav taws xob. Nyob rau hauv kev tsim kho ntawm 10kV thiab hauv qab cov kab hluav taws xob, nro clamps feem ntau siv nyob rau hauv lub davhlau ya nyob twg ncej hom, ceg ncej hom, nro ncej hom, thiab kaum ncej hom fais fab kab. Feem ntau siv nro clamps suav nrog bolt hom aluminium alloy nro clamps (NLL) thiab malleable cam khwb cia hlau nro clamps (NLD).
Thaum txhim kho nro clamps, peb yuav tsum tau ceev cov screws tusyees. Nws yuav tsum tsis txhob muaj kev ntxhov siab ntxiv ntawm cov xaim ntawm qhov chaw sib txuas ntawm cov xaim thiab cov hlau, txhawm rau tiv thaiv cov hlau puas los ntawm lub teeb cua vibration lossis lwm yam hlau oscillations, thiab xyuas kom meej tias lub zog tuav ntawm qhov nro clamp rau. cov hlau tsis tsawg dua 95% ntawm cov hlau tensile lub zog.
