txhawm rau txo qhov cuam tshuam ntawm hluav taws xob tam sim no, piv txwv li, thaum muaj hluav taws xob tawm tsam, siv cov hlau tshwj xeeb: galvanized lossis stainless hlau. Nws kuj yog siv los ua ib qho tshwj xeeb yoog rau cov khoom siv hluav taws xob thiab txo qhov kev pheej hmoo ntawm hluav taws xob poob siab rau cov neeg uas yuav nyob ze cov khoom siv hauv cov khoom siv hluav taws xob hauv cov khoom siv hluav taws xob. Cov khoom siv zoo li no yog qhov tsim nyog raws li kev tiv thaiv rau ntau cov xov hlau thiab cov cables uas nyob hauv thaj chaw nyob. Tsis tas li ntawd, xws li ib lub sawb tuaj yeem siv los tso zis hluav taws xob hauv cov kav dej. Qhov no pab ua kom cov kav dej kav ntev dua thaum txo qhov cuam tshuam ntawm corrosion.
Nws yog ib qho tsim nyog sau cia tias cov hlua hlau tuaj yeem siv los txo qhov kev pheej hmoo ntawm hluav taws xob poob rau tib neeg thiab txo kev ntxhov siab ntawm lub hauv paus chiv keeb. Ua li no, lub voj voog loj loj yog tsim los ntawm nws, uas tau teeb tsa hauv av ntawm qhov tob ntawm 0.5 meters ib ncig ntawm tag nrho ib puag ncig. Vim yog txheej txheej ntawm cov hlau sawb nrog zinc lossis stainless hlau, nws lub neej kev pabcuam tau nce 30-50 xyoo.
Thaum siv hluav taws xob, ib txwm muaj qhov tshwm sim siabxwm txheej txaus ntshai rau tib neeg. Yog li ntawd, txhawm rau kom tsis txhob muaj teeb meem, siv ib lub sawb hlau - qhov no yog cov cuab yeej txhim khu kev qha uas yuav tsum tau siv thaum ua hluav taws xob hauv tsev thiab hauv kev lag luam. Rau cov khoom siv hauv av hauv tsev, ntxiv rau cov sawb zoo li no, nws yog ib qho tsim nyog yuav tau yuav lub vaj huam sib luag fais fab, tus neeg xyuas pib hauv av, cov xov hlau thiab cov khoom siv hluav taws xob.
Tsis tas li ntawd, cov hlau nplaum yuav tsis siv rau hauv av yog tias cov khoom siv hluav taws xob hauv av tau teeb tsa hauv tsev kom muaj kev nyab xeeb: cov kav dej, lub tsev thav duab (ua los ntawm hlau), tab sis yog tias lawv nyob hauv av, zoo li cov kav dej. Thaum siv tej yam ntuj tso grounding conductors, nws yog ib qhov tsim nyog los nqa tawm ib tug tshwj xeeb qhov hluav taws xob, uas yog, mus nteg ib tug grounding tshwj xeeb xaim los ntawm cov qauv mus rau lub busbar ntawm lub hluav taws xob vaj huam sib luag. Cov ceg txuas nrog bolts lossis vuam.
Rau cov khoom siv hauv av, koj yuav tsum xub khawb ib lub trench uas yuav khiav ntawm cov khoom mus rau qhov chaw ntawm qhov tshwj xeeb Circuit Court. Nyob rau hauv qhov chaw ntawm no contour, lub trench yuav siv daim duab peb sab, nyob rau hauv txhua txhua vertex uas nws yog tsim nyog los laum qhov dej mus rau ib tug tob ntawm peb meters. Tom qab ntawd ib lub strip ntawm stainless hlau los yog zinc coated yog pw, thiab steel rods kuj hammered. Tom qab ntawd tag nrho cov qauv yog them nrog ib txheej ntawm excavated av, nyob rau hauv uas yuav tsum tsis muaj khib nyiab thiab rubble. Txhawm rau txo qhov tsis kam ntawm lub voj voog, nws tseem txuas nrog lub laj kab hlau lossis kev txhawb nqa. Vuam chaw yog them nrog bituminous kua roj vanish los tiv thaiv corrosion.
Thiab thaum kawg, yog tias peb-theem hluav taws xob nqa los ntawm cov kab hluav taws xob overhead mus rau hauv tsev, tsis yog tsuas yog siv cov hlua hauv av xwb, tab sis kuj tseem muaj kev tiv thaiv ntxiv - tus neeg xyuas pib nruab nrab ntawm kev nkag mus rau lub zog. daim ntaub thaiv. Cov cuab yeej no yuav tsum tau txuas nrog lub voj hauv av. Nws yog qhov yooj yim heev thiab kev lag luam ntawm cov nyiaj los ua ib qho contour ntawm theem ntawm kev tso lub hauv paus lossis cov dej ntws tawm.
