three phase dry type transformer isolation transformer

Working principle

Input side winding and output side winding is isolated and no connection ,which  change voltage by induction

Connection symbol

Y/YO(make as the customer requested)

Rated voltage

Input: 3L380V  output :3L220V(make as the customer requested)

Insulation grade

Dry type F Grade 155°C(H grade 180°Ccan make according to customer requirement)

Equipment efficiency

>93%

Voltage regulation

<3%

Voltage range

<1%

Frequency

50/60HZ+-5%

Isolation Voltage

Primary and primary,primary and core,secondary and core is all 3500V/10ma/60s no breakdown

Noise

<50db when no load , <60db when full load

Ambient temperature

-20—45  degree

Humidity

<95%(no Condensing)

Cooling way

Natural ventilation for bare metal transformer,forced cooling for Packing transformer
