(1) Cov khau tiv thaiv ntiv taw. Feem ntau yog tiv thaiv cov khoom los ntawm kev mob ntawm ko taw thiab ntiv taw. Xws li dov nruas thaum nqa cov khoom hnyav lossis thauj khoom thiab thauj khoom, cov kav dej hnyav hnyav los tsoo cov taw lossis tsis pom kev ncaws pob hlau hlau. Lub taub hau pem hauv ntej ntawm cov khau yog lined nrog cov khoom siv hlau uas muaj kev cuam tshuam zoo, siab zog thiab lub teeb yuag. Nws lub zog thiab kev cuam tshuam tsis zoo yuav tsum raug kuaj thiab tus qauv siv tau. Ua tib zoo xaiv cov khau kev nyab xeeb ntawm cov khoom sib txawv raws li qhov hnyav ntawm kev ua haujlwm.
(2) Insulated khau. Lub luag haujlwm ntawm cov khau insulated yog kom txo qhov kev pheej hmoo ntawm hluav taws xob poob siab. Vim tias tam sim no ntws mus rau hauv av los ntawm tib neeg lub cev los ntawm qhov chaw sib cuag thaum siv hluav taws xob, tsis yog cov hnab looj tes insulated nkaus xwb tab sis kuj tseem muaj cov khau insulated rau kev ua haujlwm hluav taws xob. Raws li lub siab ntau yam, muaj ntau yam insulated khau ntawm 20kV, 6kV thiab 5kV, uas yuav tsum tau xaiv raws li kev ua hauj lwm ntau yam. Insulated nkawm khau yuav tsum tau kuaj xyuas thiab khaws cia tsis tu ncua. Yog lawv ntub los yog hnav, lawv yuav tsis tiv thaiv.
(3) Anti-static thiab conductive khau. Cov khau tiv thaiv zoo li qub yog tsim los tiv thaiv cov xwm txheej tshwm sim los ntawm hluav taws xob zoo li qub hauv tib neeg lub cev, thiab tsis txhob cuam tshuam hluav taws xob cuam tshuam rau tib neeg lub cev los ntawm 220V fais fab zaus cov khoom siv capacitor. Cov khau khiab yog siv rau hauv qhov chaw uas hluav taws kub lossis tawg tuaj yeem tshwm sim uas muaj kev nkag siab zoo dua rau tib neeg hluav taws xob zoo li qub. Qee yam ntawm cov khau no yog khau kev nyab xeeb thiab cov khau roj hmab nrog cov khoom tiv thaiv zoo li qub lossis cov khoom siv hluav taws xob. Tag nrho cov khau tsis siv hlau los txo qhov muaj peev xwm ntawm kev sib txhuam thiab hluav taws. Cov khau yog sim rau kev tiv thaiv los ntawm qhov pib. Tom qab ntawd nws raug kuaj xyuas ib ntus kom ntseeg tau tias qhov siab tshaj plaws ntawm cov khau tsis pub tshaj tus nqi tso cai.
(4) Steelmaking khau thiab khau npog. Cov khau no tseem hu ua khau caster, feem ntau los tiv thaiv kev kub hnyiab ntawm ko taw. Cov khau no tiv taus siab thiab tsis yooj yim rau hlawv. Sab saum toj yog ua los ntawm roj-impregnated cowhide thiab canvas-inlaid tawv. Lub khauj khaum yog ua los ntawm lub log-lined nyuj tawv. Txhawm rau tiv thaiv cov scalding ntawm molten hlau splashing kua, lub duav siab yog yooj yim tshem tawm. Cov khau npog thiab cov ris tsho hauv qab kuj tseem tuaj yeem npog nrog cov khau npog, thiab cov khau npog feem ntau yog ua los ntawm canvas, asbestos thiab aluminium film.
(5) Roj hmab khau boots. Raws li kev siv, nws muaj cov khau tiv thaiv acid, khau tiv thaiv dej thiab khau roj-pov thawj. Cov kua qaub-pov thawj thiab alkali-resistant khau boots yog haum rau qhov chaw uas cov av muaj kua qaub thiab alkali thiab lwm yam corrosive kua. Lawv yog ua los ntawm cov kua qaub thiab alkali resistant roj hmab, thiab kuj muaj anti-acid thiab alkali ris khau boots nrog ris thiab khau boots. Cov khau khiab tsis muaj dej yog siv rau hauv av los yog txaws. Cov ntaub ntawv yooj yim yog roj hmab, miner waterproof khau looj plab hlaub, khau tshwj xeeb rau cov khoom hauv dej, thiab cov khau khiab hloov. Cov khau roj hmab yog siv rau kev ua haujlwm oily hauv av, ua los ntawm cov roj hmab lossis polyethylene yas, thiab muaj cov khau thiab khau.
(6) Cov khau txias-pov thawj. Nws yog haum rau hnav nyob rau hauv qhov chaw txias thiab tsis kub. Nws muaj cov khau paj rwb, khau ntaub plaub thiab khau boots, thiab lwm yam. Nws muaj kev ua haujlwm zoo thermal rwb thaiv tsev.
