S11 20kv Oil Type High Voltage Transformer
Our transformer is equipped characters as low loss, low noise, strong protection for thunder and lighting, well anti-shortcut capacity and fine appearance etc. It combines advanced equipment and manufacturing process, and it has four remote functions: remote communication, remote test, remote adjustment and remote control. By remote control from a computer, the power station could be work without any works on watch on the night. All our transformer has passed the test by National Mechanical & Industrial Bureau and National Power Company. The transformer is mainly used in power network, and the projects of power distribution. 20KV transformer
Core equipped with advanced three steps: vertical and horizontal and horizontal cut, lap and multi-stage. It disperses the air distribution, improve the magnetic path. Decrease the no load loss, no load current and noise. 20KV transformer
Core adopts series measures dragged panel, pressed the coil, particular glue for silicon steel to increase the strength of mechanism. 20KV transformer
New structure of high and low voltage winding, reasonable arrangement for oil tube and connection which increasing the capacity of mechanical strength and anti-shortcut.
The tank is bell type or core suspension type, the wall of tank is as wave form.
