Thumela i-imeyileNjengeentambo zamandla ezintathu okanye ezine ze-conductor zilinganiswe ngama-volts angama-600, i-90 deg.C. kwiindawo ezomileyo okanye ezimanzi.
Ivunyiwe ngokukodwa ukufakela kwiitreyi zentambo ngokweSiqendu 340 se-NEC.Uhlobo lweentambo ze-TC zivumelekile ukuba zisetyenziswe kwiCandelo loku-I kwiCandelo lesi-2 kwiindawo ezinobungozi zoshishino nge-NEC nganye.Iikheyibhile zinokufakwa kumoya osimahla, kwiindlela zomdyarho okanye kwindawo yokungcwaba ngokuthe ngqo, kwiindawo ezimanzi okanye ezomileyo.Zonke iintambo xa zisetyenziswe ngokuhambelana ne-NEC, zihlangabezana neemfuno ze-OSHA.
Umqhubi wentambo unokuba lubhedu okanye i-aluminium okanyeingxubevange aluminiyam.Inani lee-cores linokuba yi-1, 2, 3, kunye ne-4 kunye ne-5 (i-4 kunye ne-5 idla ngokuba yi-low-voltage cables).
Ukuxhotyiswa kwentambo kunokwahlulwa ibe yintsimbi yentsimbi kunye nentsimbi ye-tape yokuxhobisa, kunye nesixhobo sokuxhobisa esingenamagnetic esisetyenziswe kwintambo ye-AC eyodwa.
Ulwakhiwo:
Abaqhubi be-copper e-Stranded, i-XLP (i-Cross-Linked Polyethylene) i-insulated, i-Method 1 - i-Table E1 okanye i-E2 enemibala enemibala, okanye iNdlela yesi-4 echongiweyo.Iikhonduki ezigqunyiweyo ezifakwe kwintambo yomqhubi wesiseko sobhedu kwi-interstice enye, iteyiphu yentambo, ijacket yePVC (i-Polyvinyl Chloride), eprintiweyo ngaphezulu.
Imigangatho:
Abaqhubi bahambelana ne-ASTM B-3 & B-8.
Abaqhubi abazimeleyo bahambelana ne-UL Standard 44, kwaye bamkelwe njengoHlobo lwe-XHHW-2.
I-TC Uhlobo lweCable yeTreyi ngeNqaku le-340 le-NEC.
Iintambo ezifanelekileyo kwi-Sunlight Resistant applications.
Iintambo ezenzelwe ukuphumelela iimvavanyo zedangatye ze-IEEE-383 kunye ne-IEEE-1202.
Iintambo ziyahlangabezana neemfuno ze-ICEA S-95-658/NEMA WC70.
