Known for its whisper-quiet operation, Qinghao transformer is ideal for urban installations where noise reduction is paramount.
Qinghao dry type distribution transformer includes cast resin, amorphous alloy and on-load tap changer type, which provides general security for environment with its non-flammable, self-extinguished, toxic gas-free structure and low noise level. It is humidity proof and suitable for operating in humid and extremely polluted environments. They are ideal transformers to work at -40°C and more than 95% humidity level. Our dry type distribution transformer primary voltage range includes 6,6.3,10.5,11,20,22,24,33, 35,38.5kV and max rating can up to be 3150kVA, which can be manufactured according to customer requirements.
