1. Cov khoom tseem ceeb ntawm cov plooj (porcelain insulator) muaj xws li: zoo tib yam disc suspension porcelain insulator, cov pa phem resistant disc suspension porcelain insulator, straw hat disc suspension porcelain insulator, ground wire disc suspension porcelain insulator, post porcelain insulator, pin porcelain arm insulator, porcelain cross arms insulator , post porcelain insulator, npauj npaim porcelain insulator, nro porcelain insulator thiab tram porcelain insulator;
2. Cov khoom tseem ceeb ntawm cov iav insulator muaj xws li: txheem disc ncua kev kawm ntawv iav insulator, muaj kuab paug resistant disc ncua kev kawm ntawv iav insulator, aerodynamic disc ncua kev kawm ntawv iav insulator thiab av hlau iav insulator;
3. Cov khoom tseem ceeb ntawm cov khoom siv hluav taws xob muaj xws li: cov khoom siv hluav taws xob sib txuas, cov khoom siv hluav taws xob sib txuas, cov khoom siv hluav taws xob sib txuas, cov khoom siv hluav taws xob sib txuas, cov hluav taws xob hluav taws xob sib txuas, cov hluav taws xob tiv thaiv hluav taws xob thiab cov hluav taws xob hluav taws xob hluav taws xob sib txuas;
Kev tsim technology thiab kev loj hlob theem ntawm ± 800kV DC disk ncua kev kawm ntawv, post thiab composite hollow insulator nyob rau hauv Tuam Tshoj yog soj ntsuam. Nws raug suav hais tias kev siv thev naus laus zis ntawm ± 800kV DC insulator hauv Suav teb tau mus txog qib thoob ntiaj teb. Cov kev ntseeg tau thiab kev lag luam raug soj ntsuam. Nws raug suav hais tias yog disc ncua kev kawm ntawv porcelain insulator thiab iav insulator yog piv rau kev lag luam, tab sis disc ncua kev kawm ntawv cov insulator muaj ntau qhov zoo; Porcelain thiab porcelain composite insulators yog sib piv hauv kev lag luam, tab sis porcelain composite insulators muaj qhov zoo dua. Txhawm rau kom ntseeg tau tias kev ua haujlwm ntawm cov insulators, nws tau hais tias 160 ~ 420kN ob lub kaus porcelain insulators yog nyiam rau lub teeb heev thiab lub teeb muaj kuab paug qib insulator ncua kev kawm ntawv "I" cov hlua, thiab cov insulators sib xyaw yog nyiam rau nruab nrab thiab hnyav cov pa phem qib insulator ncua kev kawm ntawv. "Kuv" hlua; Nws kuj tseem pom zoo kom siv cov tshuaj tiv thaiv kev ua qias tuaj tsis tu ncua flashover txheej (PRTV) rau saum npoo ntawm pillar porcelain insulator nrog cov qauv qhov siab txog li 12m.
