Yog, nws yog ib qho tseem ceeb heev rau lub laj kab hluav taws xob yuav tsum ceev kom lub laj kab ua haujlwm kom zoo thiab nyab xeeb. Muaj ob peb lub laj thawj tseem ceeb vim li cas kev nruj yog qhov tseem ceeb:
1. conductivity:
Loose, sagging xov hlau ua rau kev sib txuas hluav taws xob tsis zoo thiab ua kom tus nqi qis dua ntawm txoj kab laj kab. Qhov no txo qhov voltage mus dhau, tsis muaj zog poob siab.
2. Kev pheej hmoo hauv av:
Cov xov hlau xoob ntau dhau uas sag thiab kov cov khoom hauv av xws li cov nroj tsuag, av lossis lwm yam khoom siv laj kab tuaj yeem ua rau hauv hluav taws xob.
3. Shorting Risk:
Cov xov hlau xoob uas hla dhau los yog kov ib leeg tuaj yeem ua rau arcing thiab luv luv ntawm hluav taws xob mem tes.
4. Tsiaj kev sib tw:
Sagging, xoob xaim saib tsis tshua muaj kev ntshai thiab tuaj yeem ntxias cov tsiaj txhu kom sim thawb los ntawm lossis hauv qab laj kab.
5. Kev nyab xeeb kev nyab xeeb:
Cov kab hluav taws xob xoob xoob xoob qis tuaj yeem ua rau tib neeg poob siab yog tias tsis pom zoo thiab pom.
Feem ntau cov lus pom zoo yog kom tensions high-tensile xov hlau rau200-300 lbsntawm nro siv ratchet-style laj kab nruj los yog hauv-kab tensioners. Cov xov hlau yuav tsum tau nruj txaus kom lawv tsis tuaj yeem txav tau yooj yim lossis distorted los ntawm tes siab.
Ua kom lub laj kab hluav taws xob nruj yog qhov tseem ceeb rau kev ua kom pom kev zoo, kev tiv thaiv tsiaj, lub laj kab ntev, thiab kev ua haujlwm zoo tag nrho. Kev kuaj xyuas thiab rov ua kom nruj raws li qhov xav tau yog ib feem ntawm kev saib xyuas tsis tu ncua.
