Rau cov cables siv rau hauv kev khawb av ntawm cov xwm txheej nyuaj thiab ib puag ncig tsis zoo, muaj roj thiab smut, yooj yim ua rau muaj kev nthuav tawm, cov yas insulated hluav taws xob cables tsis yog tsuas yog muaj cov yam ntxwv hais hauv tshooj thawj zaug ntawm phau ntawv qhia no, tab sis kuj muaj cov yam ntxwv ntawm hluav taws kub retardant. Ntawm lawv, qhov uas muaj thaj tsam hla-seem siab tshaj plaws yog 50mm thiab siab dua yuav tsum dhau los ntawm kev sim combustion ntawm A hom Sau Hluav Taws Xob Hlau & cable. Yog tias tsawg dua 50mm², nws yuav tsum dhau los ntawm kev sim combustion ntawm B hom sau hluav taws xob hlau & cable.
1. Kub ua haujlwm siab
2. Kev ruaj khov thiab hluav taws kub, ua kom lub neej ua haujlwm ntawm lub cable zoo.
3. Pov thawj tawg
4. Me me sab nraud txoj kab uas hla
5. Lub zog kho tshuab siab
6. Muaj peev xwm nqa tau tam sim no loj
7. Kev tiv thaiv corrosion siab
Cov cable no yog tsim rau kev siv rau hauv kev teeb tsa ruaj khov hauv cov kab kis / faib rau cov hluav taws xob ntsuas dua 10kV xws li qhov chaw ntawm chav faib khoom nruab nrab mus rau chav electromechanical, chaw hloov pauv hluav taws xob, chaw ua haujlwm khawb av thiab switchgear. Cov cable muaj tus yam ntxwv ntawm kev tiv thaiv hluav taws kub.
