Cov theem hluav taws xob hauv Suav teb yog 220V, 380V, 10kV, 24kV, 35kV, 110kV, 220kV, 500kV, 800kV, thiab 1000kV.
Voltage theem feem ntau muab faib: 1: kev nyab xeeb voltage (feem ntau qis dua 36V); 2: Tsawg voltage (tseem muab faib ua 220V thiab 380V); 3: siab voltage (10KV-220KV); 4: ultra-siab voltage 330KV-750KV; 5: ultra-siab voltage 1000KV AC, Tshaj ± 800KV DC.
Nws feem ntau muab faib li no nyob rau txawv teb chaws:
Tsawg voltage: tsawg dua 400V
Nruab nrab voltage: 10-35kV
High voltage: siab dua 110kV thiab qis dua 500kV
Ultra-siab voltage siab tshaj 500kV
