Yeyiphi iNqanaba loKuqhushumba-Ubungqina obuphezulu, CT2 okanye CT4

Kucacile ukuba i-CT4 inomlinganiselo ophezulu wokumelana nokudubula. Ngokucacileyo, iimotor-proof-proof motors zibonisa igama le-IICT4 kodwa azinaphawu lwe-IICT2.

Iqondo lobushushu IEC/EN/GB 3836	Obona bushushu bomphezulu buphezulu besixhobo se-T [℃]	Ubushushu be-Lgnition yezinto ezitshayo [℃]
T1	450	T＞450
T2	300	450≥T＞300
T3	200	300≥T＞200
T4	135	200≥T＞135
T5	100	135≥T＞100
T6	85	100≥T＞8

Lo mahluko uvela kuhlelo lobushushu bezixhobo zombane ezingenoqhushumba: Izixhobo ze-T4 ziyilelwe ukugcina ubuninzi bobushushu bomhlaba obungaphantsi kwe-135 ° C, ngelixa izixhobo ze-T2 zivumela ubushushu obuphezulu bomphezulu ukuya kuma-300°C, kuthathwa njengomngcipheko ogqithisileyo.

Ngenxa yoko, I-CT4 lolona khetho lukhethwayo; I-CT2 iyaphetshwa ngokubanzi.
