Cov Clevis Hlau Uas Muaj Kev Ruaj Ntseg
Cov Clevis uas muaj cov rwb thaiv tsev yog ib hom clevis tshwj xeeb uas tsim los siv rau hauv cov tshuab faib hluav taws xob. Nws yog tsim los ntawm cov khoom siv rwb thaiv tsev xws li polymer lossis fiberglass, uas qhwv cov khoom hlau ntawm cov clevis kom tiv thaiv kev ua hluav taws xob. Lawv siv los txuas cov hlau conductors, xws li cov kab hluav taws xob lossis cov cables, rau cov insulators lossis lwm yam khoom siv ntawm cov ncej hluav taws xob lossis cov qauv. Los ntawm kev cais cov hlau conductor ntawm cov hlau clevis, cov khoom no pab txo qhov kev pheej hmoo ntawm kev ua txhaum hluav taws xob lossis luv luv circuits los ntawm kev sib cuag tsis raug nrog cov clevis. Spool Insulator Bracke yog qhov tseem ceeb rau kev tswj hwm kev nyab xeeb thiab kev ntseeg siab ntawm cov tes hauj lwm faib hluav taws xob.
