I-fuse yokuyekaukuphumafuthi ukusika i-fuse yokushintsha imithwalo kungokwedivayisi evikela amandla kagesi aphezulu esetshenziswa ngaphandle, i-Tobe connecte ene-incomin-g feeder ye-transformer yokusabalalisa noma imigqa yokusabalalisa, ivikela ikakhulukazi imigqa ye-transformeror kusuka kumjikelezo omfushane nokulayisha ngokweqile, kanye nokulayisha / ukuvala ukulayisha, okwamanje, i-Drop-out fuse cutout yakhiwe ngezisekelo ze-insulat insulator kanye neshubhu ye-fuse, izisekelo ezimbili eziseceleni ezithintekayo ezixhunywe ku-fix zifakwe eziphethweni ezimbili ezithintekayo. Fuse tube, Fuse tube yakhiwa ngaphakathi arcexting tube. Ishubhu yephepha ehlanganisiwe ye-phenolic yangaphandle noma i-epoxy glasstube, ukunqamula ukushintshwa kwe-fuse kokulayisha kunikeza oxhumana nabo abanwebekayo abasizayo kanye nokuvezwa kwe-arc-ecimayo ukuze kucishwe amandla okulayisha.
