Lithini iqondo lobushushu leNqanaba lokuNgqabhuka-bubungqina be-AT1

Kwindawo yokuqinisekisa ukuqhuma kombane, i “T” udidi luchaza amaqela obushushu, where T1 signifies that the device’s maximum surface temperature remains below 450°C.

Ukakhulu, izixhobo zombane ezingaqhushumbayo zihlelwa ngokwamaqela obushushu iT4, T5, kunye ne T6. Ukuhlelwa kwe-T3 kukho kodwa kunqabile.
