Iinkcukacha:

    Njengoko iintambo zombane ezisebenzisa umqhubi wesithathu okanye wesine zinomlinganiselo we-600 volts, i-90 deg. C. kwiindawo ezomileyo okanye ezimanzi.

Isicelo:

Njengoko iintambo zombane ezisebenzisa umqhubi wesithathu okanye wesine zinomlinganiselo we-600 volts, i-90 deg. C. kwiindawo ezomileyo okanye ezimanzi.
Ivunyiwe ngokukodwa ukuba ifakwe kwiitreyi zekhebula ngokweCandelo 340 le-NEC. Iintambo ze-TC zohlobo zivumelekile ukusetyenziswa kwiindawo ezinobungozi kwimizi-mveliso zeCandelo loku-1 iCandelo lesi-2 ngokwe-NEC. Iintambo zinokufakwa emoyeni okhululekileyo, kwiindlela zomdyarho okanye kwindawo yokungcwaba ngqo, kwiindawo ezimanzi okanye ezomileyo. Zonke iintambo xa zisetyenziswa ngokuhambelana ne-NEC, ziyahlangabezana neemfuno ze-OSHA.
Umqhubi wentambo unokuba yithusi okanye i-aluminium okanyei-aluminium alloyInani lee-cores lingaba yi-1, 2, 3, kunye ne-4 kunye ne-5 (4 kunye ne-5 zihlala ziintambo ze-voltage ephantsi).
Izixhobo zokukhusela intambo zingahlulwa zibe ziizixhobo zokukhusela intambo yentsimbi kunye nezixhobo zokukhusela iteyipu yentsimbi, kunye nezixhobo zokukhusela ezingezizo zemagnethi ezisetyenziswa kwintambo ye-AC engundoqo enye.

Ulwakhiwo:

Ii-conductors ze-copper eziqinileyo, i-XLP (i-Cross-Linked Polyethylene) egqunywe ngombala, Indlela 1 - Itheyibhile E1 okanye E2 enemibala, okanye Indlela 4 echongiweyo. Ii-conductors ezigqunywe ngombane ezifakwe intambo nge-stranded copper grounding conductor kwi-interstice enye, i-cable tape, ijakethi ye-PVC (i-Polyvinyl Chloride), eprintiweyo kumphezulu.

Imigangatho:

Ii-conductors zihambelana ne-ASTM B-3 kunye ne-B-8.
Ii-conductors ngazinye zihambelana ne-UL Standard 44, kwaye zivunyiwe njengohlobo lwe-XHHW-2.
Intambo yeTreyi yohlobo lwe-TC ngokweNqaku 340 le-NEC.
Iintambo ezifanelekileyo zokusetyenziswa kwi-Sunlight Resistant.
Iintambo ezenzelwe ukuphumelela uvavanyo lwelangatye lwe-IEEE-383 kunye ne-IEEE-1202.
Iintambo ziyahlangabezana neemfuno ze-ICEA S-95-658/NEMA WC70.
